Characterization and Evaluation of Taihe Black-Boned Silky Fowl Eggs Based on Physical Properties, Nutritive Values, and Flavor Profiles.

Taihe black-boned silky fowl (TS) is a native chicken breed in China with more than 2000 years of history. The present study aimed to characterize and evaluate the physical, nutritional, and flavor properties of TS eggs with a comparison to two other commercial breeds. Eggs from TS (n = 60) crossbred black-boned silky fowl (CB, n = 60) and Hy-line Brown (HL, n = 60) were used for physicochemical analysis. The evaluation system was divided into four parts based on nutrient and flavor profiles: protein and amino acids, lipids and fatty acids, mineral elements, and flavor-related amino acids and volatile compounds. Results showed that TS eggs were typically associated with the lowest egg weight and the highest yolk color, as compared with CB and HL eggs. No differences were found in crude protein, crude fat, triglycerides, and cholesterol content between eggs from the different breeds, but these eggs were distinct in terms of the amino acid, fatty acid, and volatile flavor compound profiles. Moreover, the differences in amino acid and fatty acid profiles might contribute to the specific flavor of TS eggs. Evaluation results indicated that TS egg whites may be suitable as a protein source for premature infants and young children under three years old and TS egg yolks could be considered a beneficial dietary lipid source due to their potential anti-cardiovascular properties. Additionally, TS whole eggs could serve as a valuable source of selenium (Se), molybdenum (Mo), zinc (Zn), and phosphorus (P) for adults aged 18 to 65. However, TS and CB eggs showed inferior Haugh units, eggshell quality, and essential amino acid compositions for older children, adolescents, and adults. These findings provide a better insight into the health benefits of TS eggs and contribute to the breeding and nutrition regulation of TS breeds.

[Enrichment and Nutrition/Health Risks Assessment of Mineral Elements in Apples Growing in Yunnan's High Geological Background Area].

Considering the extremely high content of soil mineral elements in high geological background areas, it is crucial to understand the transportation and health risks of mineral elements in soil-plant systems. In this study, 30 soil and apple-paired samples were collected from the main apple production areas of Yunnan's high geological background region to determine the contents of mineral elements. The aim was to research the enrichment characteristics, nutritional values, and health risks associated with 12 mineral elements in apples. The results revealed that Cd, As, Pb and Cr contents in soil samples exceeded their corresponding risk screening values with percentages of 50%, 17%, 48%, and 30%, respectively. However, only 13.3% of Pb content in apple samples exceeded the safety limit （0.1 mg·kg-1, fresh fruit）. In addition to the toxic elements, apples had higher contents of K, Ca, Mg, Mn, and Zn, with average contents of 1.241 g·kg-1, 0.045 g·kg-1, 0.061 g·kg-1, 0.648 mg·kg-1, and 0.944 mg·kg-1, respectively. The nutritional evaluation results showed that the index （INQ） of K and Cu were higher than 2 through the consumption of apples, suggesting that apple consumption was one of the primary sources of K and Cu intake. The health risk assessment revealed that the target hazard quotient （THQ） of a single heavy metal was： Cu > As > Cr > Pb > Zn > Cd； the hazard index （HI） of all heavy metals was far lower than 1, indicating that apple consumption did not pose significant heavy metal exposure risks. The results of this study will provide a scientific insight into the nutritional aspects and health risks associated with mineral elements in soil-plant systems within high geological background areas.

[Mineral content in freshwater fish in Shaanxi Province in 2021].

OBJECTIVE: To understand the mineral content of freshwater fish produced in Shaanxi Province and evaluate its related nutritional value. METHODS: According to the 2021 Shaanxi Provincial nutrition monitoring plan, the 9 mineral contents of 13 varieties of freshwater fish, produced in Shaanxi province, were determined by inductively coupled plasma atomic emission spectrometry. The nutritional evaluation of mineral elements was carried out by using the index of nutritional quality(INQ) method. Simultaneously, the correlation between 9 minerals and energy was analyzed by SPSS software. RESULTS: Among the 13 fish species, the contents of P and K were highest, with content ranges of 169-255 and 159-373 mg/100 g, respectively, followed by sodium, calcium, magnesium, iron, zinc. The contents of copper and manganese were lowest. The nutritional evaluation showed that the INQ values of P, K and Mg were than 1, the INQ value of P was highest, which was 4.57-8.72. Some fish have INQ values greater than 1 for calcium, iron, copper and zinc. The correlation between the nine minerals was not strong, as a whole. Only some elements have a correlation coefficient greater than 0.6, indicating that there was a synergistic accumulation effect or antagonistic effect in the fish body. CONCLUSION: The dominant mineral elements in different species of fish were different. However, most fish species can be used as high-quality food sources of phosphorus, potassium, magnesium, copper and zinc.

Impact of Controlling Nutritional Status Score on Mortality in Elderly Patients with Idiopathic Pulmonary Fibrosis.

Background: There are only a few reports on the nutritional status and mortality of patients with idiopathic pulmonary fibrosis (IPF). As such, this study aims to investigate the relationship between controlling nutritional status (CONUT) and the mortality of elderly patients with IPF. Methods: A total of 170 IPF patients aged ≥65 years old who visited the rehabilitation department of our hospital between July 2014 and July 2021 (mean age: 75.7 ± 6.3 years, sex (male/female): 138/32, %FVC: 78.3 ± 18.3%) were retrospectively analyzed. The Kaplan-Meier method and log-rank test were applied. Furthermore, using a Cox proportional hazards model with multivariate analysis, we analyzed the relationship between all-cause mortality and baseline characteristics including CONUT. Results: Based on the CONUT score, the normal group included 101 cases, the mild group included 58 cases, the moderate group included 11 cases, and the severe group had 0 cases. There were 49 cases of all-cause mortality events, suggesting that the mortality of the moderate group was significantly poorer than that of the normal and mild groups (p < 0.05). Furthermore, multivariate analysis identified GAP stage (HR: 5.972, 95%CI: 2.901~12.291, p < 0.0001), mMRC scale (HR: 0.615, 95%CI: 0.389~0.971, p = 0.009), and CONUT (HR: 2.012, 95%CI: 1.192~3.395, p = 0.037) as factors significantly influencing mortality. Conclusions: Severe malnutrition was not observed in elderly patients with IPF. Moderate malnutrition was associated with a significantly higher risk of all-cause mortality, suggesting that CONUT is an important indicator for predicting mortality.

Development and Validation of a Food Frequency Questionnaire for Evaluating the Nutritional Status of Patients with Serious Mental Illnesses (DIETQ-SMI) in Bahrain.

General food frequency questionnaires (FFQs) have not been tailored for or validated in individuals with psychiatric disorders. Given the unique eating behaviors of patients with serious mental illnesses (SMIs), custom-made tools are needed. Therefore, we developed and validated an FFQ customized to individuals with SMIs. A total of 150 adults with SMIs (schizophrenia, bipolar disorder, or major depression) were recruited from Bahrain. The participants completed the 50-item Dietary Intake Evaluation Questionnaire for Serious Mental Illness (DIETQ-SMI) FFQ and a 3-day food record (FR). The validity of the FFQ was assessed by comparing nutrient intake to FR intake using correlation and reliability statistics. The DIETQ-SMI demonstrated a good ranking validity compared to the FR based on correlation coefficients (rho 0.33 to 0.92) for energy and macro- and micronutrients. The FFQ had high internal consistency (McDonald's omega = 0.84; Cronbach's alpha = 0.91) and test-retest reliability (ICC > 0.90). The FFQ tended to estimate higher absolute intakes than the FR but adequately ranked the intakes. The FFQ value was correlated with the FR for all the items (p < 0.001). The DIETQ-SMI is a valid and reliable FFQ for ranking dietary intake in individuals with an SMI. It can help assess nutritional status and, subsequently, guide interventions in high-risk psychiatric populations.

Nutritional, Shelf-Life, and Sensory Evaluation of Cucumis callosus Based Optimized Syrup.

Cucumis callosus or "Choti kachri" is feral species of Cucurbitaceae family grown commonly in the semi-arid zones. The current study aimed to optimize and develop a syrup by utilizing C. callosus. For optimization of various combinations of C. callosus (CC) and Malus domestica (MD), various treatments were prepared namely T1 (100:00), T2 (75:25), T3 (50:50), T4 (00:100). The developed syrups were analyzed for nutritional and sensory analysis for a storage period of three months. The maximum and minimum range of different blends and storage period for various parameters were reported as TSS (oBx) (65.06 ± 0.23 to 67.17 ± 0.25), pH (4.67 ± 0.17 to 5.02 ± 0.65), acidity (%citric acid) (0.61 ± 0.02 to 0.98 ± 0.11), reducing sugars (%) (35.98 ± 0.12 to 44.12 ± 0.03), total sugars (%) (57.12 ± 0.03 to 65.51 ± 0.07), and non-reducing sugars (%) (14.88 ± 0.19 to 26.65 ± 0.11). All the blends varied non- significantly in terms of TSS, pH and acidity while significant (p ≥ 0.05) difference was noted in sugars when blended with 75:25 ratio of CC: MD. The data with respect to storage study reveals that the TSS, PH and acidity varied non-significantly while reducing sugars increased significantly. However, total, and non-reducing sugars decreased significantly with the increase of storage period. The prepared blends were subjected for sensory evaluation using 9-point hedonic scale for assessing color, consistency, taste, aroma, and overall acceptability with noted values as 8.0 ± 0.54 to 7.0 ± 0.44, 7.2 ± 0.54 to 8.0 ± 0.70, 7.0 ± 0.44 to 8.0 ± 0.70, 7.2 ± 0.44 to 8.0 ± 0.70, and 7.2 ± 0.44 to 8.0 ± 0.83. The study indicated that C. callosus is an acceptable source for development of syrup.

A la par de los niveles de estado nutricional determinados, se halló que el 19,5% se encontraba con sobrepeso y obesidad. Conclusiones: los niveles hallados en el estudio fueron riesgo de desnutrición (27,3%), desnutrición (16,9%) y estado nutricional normal (36,3%). Las mujeres y personas mayores de 80 años presentan mayor proporción de desnutrición y riesgo de desnutrición. Esta información demuestra la importancia de incluir un instrumento de valoración nutricional en la consulta geriátrica para el diagnóstico y tratamiento oportunos.

Introduction: The nutritional status of older people can vary depending on environmental, psychosocial, and physiological factors. Objective: To assess the nutritional status of elderly people institutionalized in a public senior residence in Asunción, Paraguay. Methodology: An observational, descriptive, cross-sectional study carried out in men and women over 60 years of age, institutionalized in the Santo Domingo Complex of the city of Asunción in July 2023. The instrument used to assess the levels of malnutrition and risk of malnutrition was the Full MNA® (Full-Mini Nutritional Assessment). To measure overweight and obesity, the table of weight-age percentiles in the older adult population was used. Results: We worked with 77 older people with a mean age of 77 ± 9 years (range 60 and 106 years), with 54.6% (n 42) being female. At the "malnourished" level, 16.9% of the sample was identified, while 27.3% were at the "risk of malnutrition" level and 36.3% had a "normal state of nutrition" Along with the determined nutritional status levels, it was found that 19.5% of this population was overweight and obese. Conclusions: The levels found in the study were risk of malnutrition (27.3%), malnutrition (16.9%), and normal nutritional status (36.3%). Women and people over 80 years of age have a higher proportion of malnutrition and risk of malnutrition. This information demonstrates the importance of including a nutritional assessment instrument in the geriatric consultation for timely diagnosis and treatment.

Incidence, Outcomes, and Predictors of Subphenotypes of Acute Kidney Injury among Acute Respiratory Distress Syndrome Patients: A Prospective Observational Study.

Background: Acute kidney injury (AKI) is a heterogeneous syndrome with subphenotypes. Acute kidney injury is one of the most common complications in acute respiratory distress syndrome (ARDS) patients, which influences mortality. Material and methods: It was a single-center observational study on 266 ARDS patients on invasive mechanical ventilation (IMV) to determine the subphenotypes of AKI associated with ARDS. Subphenotyping was done based on the serum creatinine (SCr) trajectories from day 1 to day 5 of IMV into resolving (subphenotype 1) or non-resolving (subphenotype 2) AKI. Results: Out of 266 ARDS patients, 222 patients were included for data analysis. 141 patients (63.51%) had AKI. The incidence of subphenotype 2 AKI among the ARDS cohort was 78/222 (35.13%). Subphenotype 2 AKI was significantly more among the non-survivors (87.7% vs 36.2 %, p < 0.001). Subphenotype 2 AKI was an independent predictor of mortality among ARDS patients (p < 0.001, adjusted odds ratio 8.978, 95% CI [2.790-28.89]. AKI subphenotype 1 had higher median day 1 SCr than subphenotype 2 but lower levels by day 3 and day 5 of IMV. The median time of survival was 8 days in AKI subphenotype 2 vs 45 days in AKI with subphenotype 1 [Log-Rank (Mantel-Cox) p < 0.001]. The novel DRONE score (Driving pressure, Oxygenation, and Nutritional Evaluation) ≥ 4 predicted subphenotype 2 AKI. Conclusion: The incidence of subphenotype 2 (non-resolving) AKI among ARDS patients on IMV was about 35% (vs 20% subphenotype 1 AKI), and it was an independent predictor of mortality. The DRONE score ≥4 can predict the AKI subphenotype 2. Highlights: The serum creatinine trajectory-based subphenotype of AKI (resolving vs non-resolving) determines survival in ARDS patients. Non-resolving AKI subphenotype 2 is an independent predictor of mortality in ARDS. The novel DRONE score (driving pressure, oxygenation, and nutritional evaluation) ≥ 4 within 48 hours of IMV predicted the AKI subphenotype 2 among ventilated ARDS patients.

[Protein efficiency ratio of genetically modified pork powder with fat-1 gene].

OBJECTIVE: To evaluate the protein efficiency ratio(PER) of genetically modified pork powder with fat-1 gene(GM group), and thus evaluate whether the nutritional evaluation value of fat-1 gene pork powder has changed. METHODS: Sixty weaned SD rats(60-80 g) were randomly divided into casein group, parental control group and GM group according to sex and weight, 20 rats in each group, half of each sex. The rats in the three groups were fed with corresponding formulated feed containing 10% protein for 28 days. The body weight and food intake of each group were recorded weekly. Blood was collected at the end of the experiment to determine hematology and blood biochemical indexes. The food utilization rate, organ/body weigh indexes, PER and corrected PER were calculated. RESULTS: The weight of rats in all groups increased steadily during the experimental period. Statistically significant differences were found in some hematology and blood biochemical indexes and organ/body weigh indexes. No biologically significant changes were found. The food utilization rate of GM group was higher than that of casein group(P<0.05), which was equivalent to that in the parental control group. The PER of both genetically modified pork powder with fat-1 gene and parental white pork powder were higher than that of casein(P<0.05). CONCLUSION: The PER of genetically modified pork powder with fat-1 gene was equal to that of its parental white pork powder.

Detrimental influence of industrial effluents, especially heavy metals, on limnological parameters of water and nutritional profile in addition to enzymatic activities of fish, Sperata seenghala (Sykes, 1839) from diverse Ramsar sites, India (Punjab).

The present research was designed to determine the nutritive value of the liver and intestine of fish, Sperata seenghala, the impact of effluence load on limnological parameters of water and proximate composition of fish organs, especially on fatty acids, liver enzymatic activities, seasonal variations in the nutritional profile of fish, and to check and compare the pollution status of Ramsar sites in Punjab by calculating the water quality index, heavy metal pollution index, and metal index from June 2018 to August 2020. WQI of Harike wetland was found to be 53.95, which depicts that water quality in this region is "poor". At Nangal wetland, water quality index was reported to be "excellent" quality water and fit for the whole ecological unit. Overall heavy metal pollution index for Harike wetland was reported 174.569, whereas for Nangal wetland it was 5.994, depicting massive contaminant loads in a polluted region. MI value was also recorded as being higher (6.9336) in polluted habitat than in control habitat (0.8175). In fish liver, significant (p < 0.05) higher mean total lipids (6.73%), total proteins (3.98%), moisture (77.69%), ash (3.56%), and carbohydrates (3.79%) were observed in the samples from Nangal wetland than Harike wetland. A similar trend was reported in all biochemical contents of the fish intestine. Enzyme activities such as aspartate-aminotransferase and alanine-aminotransferase were significantly elevated (p < 0.05) in the specimens collected from the polluted region. The mean total n-3 (except in spring), n-6 polyunsaturated fatty acids (except in winter), and average monounsaturated and saturated fatty acids diminished significantly (p < 0.05) in the liver of fish from contaminated habitat than control site. In the intestine of fish collected from the polluted region, significant reductions in the mean total n-3 (except in autumn as well as summer), total n-6 PUFAs (in autumn and winter), and total SFAs were reported than control site.

Composition and contents of fatty acids and amino acids in the mycelia of Lentinula edodes.

With the global shortages of animal protein foods, mycoprotein as a low-cost alternative source of protein by its high-protein and low-fat content has become a development trend. Lentinula edodes (L. edodes) is a healthy food with high protein and low fiber. This work evaluated the nutritional value of L. edodes mycelia, and determined the composition and contents of fatty acids and amino acids. Eleven saturated fatty acids (SFAs) and 12 unsaturated fatty acids (UFAs) were detected in the mycelia of L. edodes. The UFA content accounted for 75.7% and 73.1% of the total fatty acid content in the mycelia of strains 18 and 18N44, respectively. Linoleic acid was the major polyunsaturated fatty acid (PUFA) in the mycelia, accounting for 91.0% and 86.3% of the UFAs, respectively. The mycelia of the two strains contained 17 types of amino acids, and the essential amino acids were sufficient (357.92 ± 0.42 and 398.38 ± 4.52 mg/g pro, respectively), both close to the WHO/FAO reference protein pattern value. The most abundant essential amino acid was Lys, and the limiting amino acids were Met + Cys and Ile, respectively. The SRC values in the mycelia of the two strains were 68.07 and 54.86, and the EAAI values were 67.70 and 74.42, respectively, both being close to those of ovalbumin. It is concluded that L. edodes mycelia are rich in easily absorbed high-quality proteins and PUFAs, and can be used as a source for meat analog required by vegetarians. This study provides a scientific basis for the further utilization of mycelial resources.

Is there a difference in the parameters of the bioelectrical impedance obtained from devices from different manufacturers? A cross-sectional study in hospitalized cancer patients.

BACKGROUND: Cancer is a disease with high and increasing incidence rates in the world and its course tends to harm the body composition. Monitoring these body changes is very important. Therefore, it is essential to have reliable, accessible, and practical methods for evaluating body compartments. This study aims to evaluate the correlation and agreement of results for the bioelectrical impedance analysis (BIA) obtained from devices from different manufacturers. METHODS: This is a single-center cross-sectional study including hospitalized patients with cancer. Two devices from different brands used for obtaining the BIA were used; both with a tetrapolar model and a single frequency (50 kHz). The results were evaluated for resistance (R) and reactance (Xc) and used to calculate the phase angle (PhA) and fat-free mass (FFM) indicators. Pearson and Spearman correlation tests and Bland-Altman plots were performed, with results expressed as bias and limits of agreement at 95% confidence intervals (95%CI). RESULTS: We have included 116 patients, with a mean age of 60.8 ± 14.8, 51.7% were women. We have found very strong correlations between the measurements of R (rho = 0.971) and FFM (r = 0.979), and strong correlations for Xc (rho = 0.784) and PhA (rho = 0.768). However, the measurements did not agree between the methods. CONCLUSIONS: Commercial brands of devices used for the BIA influence the results generated, a factor that must be considered when choosing the most appropriate method for this analysis.

The evaluation of the nutritional quality of common wild edible fungi in Yunnan Province.

There are huge resource reserves of wild edible fungi richer in their varieties in Yunnan Province which is located on plateau of low latitude and possesses unique various climate environments and bigger vegetative cover ratios. Moreover, nutrients and flavor substances in the same or various species of wild edible fungi differ greatly with the influence on different components from habitats and geographic areas. So, 5 common wild edible fungi were collected from different areas in Yunnan Province, and several findings were made from this research. Above all, through the evaluation of amino acids, these 5 fungi met the criteria for ideal protein by WHO/FAO, and the nutritional value of protein was ranked as matsutake > truffle > collybia albuminosa > bolete > chanterelle. Next, after the analysis of taste activity values, the ranking of taste was bolete > collybia albuminosa > truffle > matsutake > chanterelle. Subsequently, the ranking of characters was truffle > collybia albuminosa >bolete > matsutake > chanterelle through principal component analysis. Finally, truffle could be completely divided by Fisher discrimination analysis with a bigger difference from others, main in ash, protein, sugar, and polysaccharide, meanwhile, truffle and bolete could be completely divided by orthogonal projections to latent structures discrimination analysis, main in protein, crude fiber, fat, and amino acid. So, there was a more conspicuous difference in nutrients among fungi, through which nutrients combined with multivariate statistics analysis made possible the correct differentiation of small range categories in wild edible fungi, and the correct classification of small range of them could effectively be realized.

Assessment of the nutritional status of patients before, one, and three months after liver transplantation: A multi-center longitudinal study.

BACKGROUND: Nutrition management is an important pre-operative and post-operative challenge in liver transplantation. Preoperative malnutrition is associated with increased length of intensive care unit (ICU) stay, mortality, and length of hospital stay in liver transplant patients. This study aimed to evaluate the nutritional status of patients before and after liver transplantation and post-transplant complications. METHOD: This longitudinal study was conducted on liver transplant patients in Montaserieh Hospital, Mashhad and Firoozgar Hospital, Tehran from May 2021 to January 2022. Demographic characteristics, Subjective Global Assessment (SGA) standard questionnaire, anthropometric indices, laboratory analyses, and 3-day food records were collected before, one, and three months after transplantation. RESULTS: Thirty-nine patients with a mean age of 48.4 ± 14.2 were evaluated. Prevalence of severe malnutrition was 43.6% (56.3% women and 34.8% men) before transplantation. Body mass index (BMI), body weight, lean mass, total body water, and total serum protein significantly decreased after transplantation compared to before transplantation (P < 0.001). One month after transplantation, 54% of the patients lost more than 10% of their weight. Energy intake increased significantly after transplantation (P < 0.001). A significant relationship was observed between BMI (P = 0.005) and metabolic complications and between Arm Muscle Circumference and renal complications (P = 0.003) after transplantation. A cut-off point of 4.6 was determined for the phase angle in terms of SGA three months after transplantation. CONCLUSION: Malnutrition, weight loss, and nutritional problems were common in liver transplantation patients. Screening for nutritional status is necessary in these patients to treat or prevent malnutrition-related complications.

Structure analysis and quality evaluation of plant-based meat analogs.

The growing world's population increases the demand of proteins. Meat products as the major source of high protein food are facing environmental impacts and animal welfare issues. Therefore, plant-based meat analogs are developed and gain a foothold in global markets. The structure design, sensory attributes and nutrient characteristics of meat analogs are crucial points to match the real meat. This review aimed to systematically introduce the structural analysis methods and evaluate meat analog products from quality-related attributes. First, various strategies of analyzing the fibrous structure of meat analogs were illustrated, including microscopic imaging and several optical techniques. Then, representative techniques such as NMR and AFM-IR for analyzing the distribution of moisture and lipid in meat analogs are introduced. In terms of quality, we elaborated on the texture and sensory evaluation methods and dialectically analyzed meat analogs' nutrition, which can provide a guidance for the advanced development of meat analogs.

Amino Acid Profiles and Nutritional Evaluation of Fresh Sweet-Waxy Corn from Three Different Regions of China.

This study conducted a comparative analysis of the amino acid compositions of Chinese Huangnuo 9 fresh sweet-waxy corn from three different provinces in China-Inner Mongolia, Jilin, and Heilongjiang Province. Moreover, we established a nutritive evaluation system based on amino acid profiles to evaluate, compare, and rank the fresh sweet-waxy corn planted in different regions. A total of 17 amino acids were quantified, and the amino acid composition of fresh sweet-waxy corn was analyzed and evaluated. The amino acid quality was determined by the amino acid pattern spectrum, chemical evaluations (including CS, AAS, EAAI, BV, U(a,u), NI, F, predict PER, and PDCAAS), flavor evaluation, amino acid matching degree evaluation, and the results of the factor analysis. The results showed that the protein content of fresh corn 1-1 from Inner Mongolia was the highest (40.26 ± 0.35 mg/g), but the factor analysis results, digestion, and absorption efficiency of fresh corn 1-2 were the best. The amino acid profile of fresh corn 1-1 was closest to each evaluation's model spectrum. The results of the diversity evaluations in fresh corn 3-2 were the best, and fresh corn 3-3 had the most essential amino acid content. A total of 17 amino acids in fresh corn were divided into three principal component factor analyses: functional principal components (Leu, Pro, Glu, His, Ile, Ser, Met, Val, Tyr, Thr), regulatory principal components (Lys, Gly, Ala, Asp, Arg, Trp), and protection principal components (Phe). The scores of the three principal components and the comprehensive score in fresh corn 1-2 were all the highest, followed by 3-3 and 1-1. The amino acid nutritional values of fresh corn 1-2 were the highest in 12 samples.

Physical properties, chemical composition, and nutritional evaluation of common salad dressings.

Salad dressings (SDs), a subcategory of flavored sauces with more than 20% fat content and less than 30% moisture content, is favored by consumers due to its delicacy. The physical properties, chemical composition and nutritional evaluation of common SDs on the Chinese market needs to be systematically investigated. This study compared the quality (physical properties, proximate composition, amino acids, fatty acids, and minerals) of six commercially available sweet SDs (SD1, SD2, SD3, SD4, SD5, and SD6) from the Chinese market. The results indicated that the water activity of six SDs was less than 0.60 (0.35-0.41), the moisture content was less than 65% (24.0-60.0%), and the crude fat content was between 23.25 and 64.15%. The essential amino acid index (EAAI) of SD3, SD1, SD2, and SD4 was greater than the FAO/WHO standard (EAAI = 75). Numerous fatty acids were detected, mainly linoleic and oleic acids; n-3 polyunsaturated fatty acids were ranged from 1,090 mg/100 g to 2,520 mg/100 g. In addition, SDs were rich in minerals such as Mg, Ca, and Fe and the atherogenic index and thrombogenic index were 0.03-0.09 and 0.77-0.91, respectively. In summary, this work helps to provide key nutritional information on the composition of common SDs. The availability of this data may help purchasers with different nutritional needs to make informed choices about the use of SD and encourage more moderate consumption of pre-packaged sauces.

[Nutritional evaluation of fatty acid compositions and the fat of Fujian characteristic snacks].

OBJECTIVE: To analyze the fat and fatty acid composition of Fujian characteristic snacks, and to evaluate their nutritional value. METHODS: The fat and fatty acid composition of Fujian characteristic snacks were analyzed by the national standards, and analyzed by statistics such as correlation analysis, nonparametric test and cluster analysis. The nutritional value of fatty acid was evaluated by unsaturated index(UI), atherogenic index(AI), thrombosis index(TI). RESULTS: The contents of crude fat and total fatty acid were 0.11-26.35 g/100 g and 0.08-17.85 g/100 g. The correlation coefficient r=0.915(P<0.01), crude fat and total fatty acid in poultry and livestock meats were higher than those in seafood(P<0.05). The main saturated fatty acids(SFA) were palmitic acid(21.80%-34.00%)and stearic acid(7.72%-21.45%), and the main unsaturated fatty acids(UFA)were oleic acid(5.38%-41.17%) and linoleic acid(2.99%-23.54%). The content of eicosapentaenoic acid(EPA) in fish noodle(0.71%) and docosahexaenoic acid(DHA) in fried fish roll, fish slide, fish noodles(0.41%, 2.12%, 1.59%)were far higher than other snacks. Polyunsaturated fatty acids/saturated fatty acids(PUFA/SFA)ratios were 0.10-0.69, there were 8 kinds of snacks with PUFA/SFA ratio value>0.4. The n-3 PUFA/n-6 PUFA ratios were 0.01-0.75, n-6 PUFA/n-3 PUFA ratios were 1.33-74.31. The n-6 PUFA/n-3 PUFA ratios of fish slide(1.33) and fish noodle(2.13) conform to the ideal ratio stipulated by the British Health Organization, and the ratio of flat food(6.36) conform to the recommended ratio of Food and Agriculture Organization. The SFA∶monounsaturated fatty acids(MUFA)∶PUFA ratios were 0.8∶1.0∶0.5-2.4∶1.0∶0.2, the ratios of pork zongzi, meat yan silk, spicy meat, pressed salted duck and fried oyster(1.2∶1.1∶0.5, 0.8∶1.0∶0.6, 1.0∶1.0∶0.7, 0.8∶1.0∶0.5 and 1.1∶1.1∶0.5) were close to 1∶1∶1. The UI of 15 snacks was 48.37-90.67. The AI was 0.40-1.44, and the TI was 0.97-2.32. When the distance scale was 9, snacks were divided into three categories, namely fish noodle, fish slide and others. Fish noodle was high EPA and DHA type, and fish slide was high DHA type. CONCLUSION: The fat and total fatty acid contents of the 15 snacks were wide, which were closely related to the raw materials and cooking style. Nutrition and health value of fish slide, fish noodles food, meat yan silk and spicy meat were high.

Fatty Acid Profiles and Nutritional Evaluation of Fresh Sweet-Waxy Corn from Three Regions of China.

Fresh corn is a kind of herbaceous plant with rich nutritive value and a reasonable composition of fatty acids; however, there is little research on methods for the systemic nutritional evaluation of fatty acids in fresh corn. The aim of the present study was to conduct a comparative analysis of the fatty acid profiles of Chinese Huangnuo 9 sweet-waxy corn from the provinces of Inner Mongolia, Jilin, and Heilongjiang by gas chromatography; to establish a nutritional evaluation system according to the impacts of nutrients from fatty acids on human health; and finally, to evaluate, compare and rank fresh sweet-waxy corn grown in different regions. Tocopherols were detected by liquid chromatography in order to demonstrate the anti-oxidation activity of fresh corn's fatty acids. The fatty acid contents and compositions of the 12 samples from the three regions are significantly different from each other. The nutrient value of the fatty acids in fresh corn was analyzed by factor analysis and a linear structural relation model, followed by the fitting and appraising of the model. The studied fresh sweet-waxy corn 1-4 from Inner Mongolia had the highest γ-tocopherol content and the closest saturated fatty acid:monounsaturated fatty acid:polyunsaturated fatty acid rate to the recommended value. The fatty acid profiles of sweet-waxy corns 2-1, 2-2, and 2-3 were the most diverse, and the comprehensive evaluation result of fresh corn 2-4 was the best; its total fatty acid content was the highest. Fresh corn 3-1 in Heilongjiang had the highest unsaturated fatty acids and lower values in its atherosclerosis index and thrombosis index, which suggested the strongest anti-atherosclerosis and anti-thrombotic ability. This work will give a reference to guide dietary choices and provide data support for dietary recommendations for residents.
