RESUMO
Non-centrifugal raw cane sugar (NRCS) is a minimally processed product from sugarcane (Saccharum officinarum L). This product contains phytochemical and nutritional compounds that benefit human health. Despite these advantages, NRCS commercialization is hindered by a lack of knowledge about its composition and, consequently, the absence of quality standards. Studies associating the nutritional composition of sugarcane varieties and their genuine products have not yet been found in the literature, and understanding this relationship can help establish quality standards for this product. Therefore, this study evaluated the mineral nutritional composition of genuine derivative NRCS produced from two sugarcane varieties obtained under different agronomic conditions at two stages of maturation to verify the relationships between raw material and the product. The obtained sugarcanes, juices, and bagasse, as well as the produced sugars, were analyzed for mineral content, such as calcium, magnesium, potassium, phosphorus, sulfur, iron, manganese, copper, and zinc, using inductively coupled plasma optical emission spectrometry. Most mineral constituents of sugarcane are in the juice in direct proportions to those in raw sugarcane. Thus, minimally processed food derivatives have nutritional characteristics equivalent to the raw materials. Consumption of NRCS contributes to meeting daily requirements for essential nutrients such as magnesium, copper, potassium, and manganese. For manganese, 25 g of NRCS, like the one produced in this study, can fulfill 22 to 76 % of an adult male's daily mineral requirements. The variation observed in the four NRCS samples, obtained from the same sugarcane variety under different maturation and agronomic conditions, was 250 %. This variation makes establishing quality parameters for mineral or ash content difficult. Therefore, setting mineral content levels for NRCS is inappropriate, as this parameter naturally depends on the raw material.

Brown sugar is a natural sweetener obtained by thermal processing, with interesting nutritional characteristics. However, it has significant sensory variability, which directly affects product quality and consumer choice. Therefore, developing rapid methods for its quality control is desirable. This work proposes a fast, environmentally friendly, and accurate method for the simultaneous analysis of sucrose, reducing sugars, minerals and ICUMSA colour in brown sugar, using an innovative strategy that combines digital image processing acquired by smartphone cell with machine learning. Data extracted from the digital images, as well as experimentally determined contents of the physicochemical characteristics and elemental profile were the variables adopted for building predictive regression models by applying the kNN algorithm. The models achieved the highest predictive capacity for the Ca, ICUMSA colour, Fe and Zn, with coefficients of determination (R2) ≥ 92.33 %. Lower R2 values were observed for sucrose (81.16 %), reducing sugars (85.67 %), Mn (83.36 %) and Mg (86.97 %). Low data dispersion was found for all the predictive models generated (RMSE < 0.235). The AGREE Metric assessed the green profile and determined that the proposed approach is superior in relation to conventional methods because it avoids the use of solvents and toxic reagents, consumes minimal energy, produces no toxic waste, and is safer for analysts. The combination of digital image processing (DIP) and the kNN algorithm provides a fast, non-invasive and sustainable analytical approach. It streamlines and improves quality control of brown sugar, enabling the production of sweeteners that meet consumer demands and industry standards.

To enhance the efficiency of composting agricultural organic waste (AOW), this study aimed to examine the impact of inoculating tomato straw compost with two distinct microbial agents: ZymoZone (ZZ), a composite microbial agent derived from the straw compost and Effective Microorganisms (EM), a commercial microbial agent. Furthermore, in order to reactivate the microorganisms within the compost during the initial high temperature phase, 10% brown sugar was introduced as a carbon source. The objective of this addition was to assess its influence on the composting process. The findings revealed that compared to the control (CK) group, the ZZ and EM treatments extended the first high-temperature phase by 2 and 1 day, respectively. Furthermore, with the addition of 10% brown sugar, the ZZ and EM treatments remained in the second high-temperature phase for 8 and 7 days, respectively, while the CK treatment had already entered the cooling stage by then. Notably, the inoculation of microbial agents and the addition of brown sugar substantially augmented the activity of lignocellulose-related hydrolases, thereby promoting the degradation of lignocellulose in the ZZ and EM treatment groups. This was confirmed by FTIR analysis, which demonstrated that the addition of microbial agents facilitated the degradation of specific substances, leading to reduced absorbance in the corresponding spectra. XRD analysis further indicated a notable reduction in cellulose crystallinity for both the ZZ (8.00%) and EM (7.73%) treatments. Hence, the incorporation of microbial agents and brown sugar in tomato straw compost effectively enhances the composting process and improves the quality of compost products.

BACKGROUND AND OBJECTIVES: Although excess white sugar intake imposes various health burdens, brown sugar is high in minerals, polyphenols, and polycosanol. However, few epidemiological studies have assessed brown sugar intake for health benefit. People in the Amami islands region, with a relatively high proportion of individuals with longevity, consume brown sugar as a type of refreshment. This cohort study was conducted in Amami to clarify the association of brown sugar intake with mortality risk and cancer incidence. METHODS AND STUDY DESIGN: Participants were recruited from the general population of Amami as part of the Japan Multi-Institutional Collaborative Cohort Study. The number of eligible participants was 5004 (2057 men and 2947 women). During the median follow-up period of 13.4 years, 274 deaths and 338 cases of cancer were observed. HRs and 95% CIs were estimated using the Cox proportional hazard model, after adjusting for sugar-related and other variables. RESULTS: After adjusting for their related confounding factors, brown sugar intake was associated with decreased HRs and a decreasing trend for all-site and stomach cancer incidence (p = 0.001 and 0.017, respectively) in women and men, and for breast cancer incidence (p = 0.034) in women. Additionally, a decreasing trend in the HRs for lung cancer incidence was observed among never and ex-smokers (p = 0.039). Decreased HRs for overall death, cancer, and cardiovascular disease were not apparent. CONCLUSIONS: Brown sugar intake was associated with decreased risk of all-site, stomach, and breast cancer incidences in the Amami population.

The different types of sugar employed in the food industry exhibit chemical similarity and are mostly dominated by sucrose. Owing to the sugar origin of and differences in production, the presence of certain minor organic compounds differs. To differentiate between sugars based on their botanical source, geographical origin, or storage conditions, commercial brown sugars and sugar beet extracts were analyzed by 1H NMR spectroscopy applying a segmented analysis by means of multivariate curve resolution-alternating least squares (MCR-ALS). Principal component analysis and partial least squares-discriminant analysis yielded excellent differentiation between sugars from different sources after the application of this preprocessing strategy; without loss of chemical information and with direct interpretation of the results. By applying a segmented analysis via MCR-ALS to 1H NMR sugar data, similar spectroscopic profiles could be differentiated. This improved the selectivity of 1H NMR spectroscopy for sugar source differentiation which can be useful for industrial sugar authentication purposes.

Background: It is well established that unrefined sugarcane products have antioxidant activity due to phytochemicals, polyphenols, and total antioxidant capacity, which may decrease inflammation and oxidative stress. Therefore, we conducted a systematic review to evaluate the association of unrefined sugar consumption with inflammatory biomarkers. Methods: Google Scholar, ScienceDirect, Scopus, Cochrane Library, and ProQuest databases were searched up to December 2021 for studies that report the effect of unrefined sugar on inflammation according to inflammatory cytokines, chemokine, and adhesion molecules as outcome measures. Results: Thirty-six studies were evaluated. Across all research, five studies (two in vitro and three animal studies) reported the effect of unrefined sugar on levels of cytokines, including IL-6, TNF-α, IL-10, IL-1ß, and IFN-γ. Additionally, the quality of the studies was assessed for risk of bias. Conclusions: it is possible to affirm that unrefined sugarcane products, including jaggery, may have a protective effect on inflammation via regulating some of the inflammatory pathways and a favorable impact on cytokines secretion according to the results of in vitro and animal model studies. However, since the findings are still insufficient, more scientific research, especially well-designed human trials, is highly recommended to conclude the outcomes confidently. Human data may encourage industries and the public to replace purified sugar with unrefined sugarcane in sugar-based food and for further health-care policy decisions.
RESUMO
OBJECTIVES: We investigated a low-glycemic index (GI), minimally refined brown sugar (MRBS) that retains a consistent amount of antioxidant polyphenols. This study aimed to determine whether MRBS has a lower postprandial glycemic response and GI value compared with other types of refined sugar (RS). Low glycemic response foods are also reported to increase satiety. Accordingly, we also evaluated satiety profiles, glycemic profiles (glucose, insulin, and glucagon), and total antioxidant capacity (TAC). METHODS: This work shows the results of two single-blind, cross-over studies (studies 1 and 2). For each study 14 healthy Malay individuals with a normal body mass index were recruited. In study 1, capillary blood samples were used to determine the GI of the tested sugars. Venous blood samples were used in study 2 to measure the concentrations of satiety hormones (peptide tyrosine, C-peptide, glucagon-like peptide-1, and leptin), TAC, plasma glucose, insulin, and glucagon concentrations at baseline (0 min) and at 60 and 120 min after consumption of the MRBS and RS formulated jellies. RESULTS: The incremental area under the curve of glucose positive control (312 ± 62.54 mmol.min/L) was significantly higher than that of other types of sucrose (P < 0.05). MRBS (GI: 54 ± 4.5 mmol.min/L) and brown sugar (GI: 50 ± 5.0 mmol.min/L) were categorized as low GI, and RS (GI: 64 ± 5.73 mmol.min/L) was in the medium category, which was significantly lower than the GI of glucose (GI: 100 mmol.min/L; P < 0.05). Likewise, there was a significant difference in satiety profiles (peptide tyrosine and C-peptide), glycemic profile (glucagon), and TAC (P < 0.05) between RS and MRBS jellies. CONCLUSIONS: The results of our work show that MRBS had a lower GI (study 1), and better satiety, glycemic profiles, and TAC (study 2) compared with RS.

A novel method was developed to determine six triazine herbicides from brown sugar samples using matrix solid-phase dispersion (MSPD) based on silica gel impregnated with deep eutectic solvent (DES) followed by high-performance liquid chromatography with photodiode array detector (HPLC/PDA). Several factors involved in the MSPD procedure such as DES type, DES content in impregnated silica gel, adsorbent-to-sample mass ratio, type and volume of washing solvent, type and volume of eluent, and grinding time were screened using single-factor experiments and then optimized using Box-Behnken design to accomplish the highest recoveries. The above method demonstrated a good linear range (20-1000 µg kg-1) with a determination coefficient exceeding 0.9962, low limits of determination (1.59-3.77 µg kg-1), acceptable limits of quantifications, and acceptable spiking recoveries (95.0-101.7%) for six triazines under optimized conditions. The proposed MSPD-HPLC/PDA method is a convenient, effective, and sensitive method for rapidly isolating and quantifying six triazines from brown sugar.

Brown sugar (non-centrifugal cane sugar) is popular for its pleasant caramel-like aroma and sweetness. Vacuum simultaneous steam distillation and extraction (V-SDE) and gas chromatography-mass spectrometry (GC-MS) was used to study the volatile fraction of brown sugar. To further determine the aroma-active compounds in brown sugar, gas chromatography-mass spectrometry-olfactometry (GC-MS-O) were used in conjunction with aroma extraction dilution analysis (AEDA), odor activity values (OAVs), and sensory evaluation to analyze the effects of the key aroma-active compounds on sweetness. A total of 37 aroma-active compounds were obtained, mainly including ketones, pyrazines, alkanes, phenols and alcohols, which contributed caramel, sweet and fruity notes to brown sugar. Among them, furfural, benzeneacetaldehyde, 2,3-butanedione, ß-damascenone, 2-methoxyphenol, dihydro-2-methyl-3(2H)-furanone, 2-furanmethanol and butyrolactone could significantly enhance the sweetness of sugar solution because of the congruency of the aroma attributes and sweetness.

Products of dark brown sugar (DBS) from different production processes and raw materials may bring different risks and benefits to human health. Therefore, this study was aimed to evaluate the quality of natural and commercial DBS products. Results showed that physicochemical properties, including pH value, turbidity, and browning degree have no significant difference between natural and commercial DBS products. Total flavonoid content of natural DBS was found to be significantly higher than that of commercial DBS (p < 0.05). Notably, the levels of harmful Maillard reaction products in natural DBS were significantly lower than that in commercial DBS as evidenced by analyses of methylglyoxal and fluorescent advanced glycation end products (p < 0.05). However, the amount of acrylamide in natural DBS was significantly higher than that in commercial DBS. In conclusion, this study provides useful information for risk-benefit assessment of DBS products, which is helpful for food safety management.

BACKGROUND: In recent decades, consumption of simple sugars has increased dramatically, which contributes to health problems including insulin resistance and obesity. In this study, we investigated the effects of high concentrations of white sugar (WS) and brown sugar (BS) on serum concentration of brain-derived neurotrophic factor (BDNF), insulin resistance, and body weight in albino rats. METHODS: Twenty-four male Wistar rats were randomly divided into three groups: control, a group treated with 15% WS, and a group treated with 15% BS. Rats were given WS and BS by gavage (daily) for 42 days. At the end of the intervention period, serum level of BDNF, insulin resistance, and body weight were measured. RESULTS: Body weight and insulin resistance were significantly increased and serum BDNF level was decreased in both WS and BS groups compared to the control group (P<0.05). In the WS-treated rats, the amount of changes in the insulin resistance, body weight, and serum BDNF level was greater compared to that in BS-treated (P< 0.05). CONCLUSION: Due to the adverse effects of consuming high levels of WS and BS on serum level of BDNF, insulin resistance, and body weight, high intakes of these sweeteners are not recommended.
RESUMO
Calcium citrate, chitosan, and chitooligosaccharide were added to sugarcane juice to investigate their effect on color, pH, antioxidant activity, reducing sugar, acrylamide and HMF mitigation in dark brown sugar production. Results showed that the content of 52-67% acrylamide in the dark brown sugar was mitigated with 0.1-1.0% chitosan addition and the reducing power of dark brown sugar increased with 0.5-1.0% chitosan addition. Furthermore, the addition of 0.5-1.0% chitosan or chitooligosaccharide increased HMF formation. Only the pH of dark brown sugar with chitosan addition was lower than that of other dark brown sugars. This is due to the low pH condition in dark brown sugar mitigating Maillard reaction and acrylamide formation. When the pH of sugarcane juice with chitosan adjusted back to pH 7 again, the acrylamide content of dark brown sugars significant increased (p < 0.05). Acrylamide and HMF are both produced through the Maillard reaction, the lower pH will cause the hydrolysis of sucrose to produce more HMF and reducing sugar. The L values and white index of dark brown sugar with 0.5-1.0% added chitosan were lower than those of control dark brown sugar (p < 0.05). High negative correlation was observed between HMF and acrylamide in the present study.
RESUMO
Providing safe fecal sludge (FS) sanitation has remained an important goal of global communities because of the high risks imposed on human health of the exposure to un-sanitized FS. This study used lactic acid fermentation as a pre-treatment technology to evaluate the sanitization effect of lactic acid bacteria (LAB) on FS. A combination of fermented rice flour and brown sugar was used as the medium to prepare LAB, and fecal coliforms were used as the indicator organisms. The addition of a LAB suspension grown in fermented rice flour and brown sugar to FS was studied to evaluate the survival of fecal coliforms. The pH decreased during ongoing lactic acid fermentation after the addition of the LAB suspension. The results revealed that fecal coliforms in reactors containing 1:1 and 2:1 w/w of FS and LAB suspension decreased to half of the initial concentration within seven days of the treatment process in comparison with that of the control reactor. Viable plate counts of 0.6â¯×â¯108, 0.9â¯×â¯108, and 2.4â¯×â¯108â¯CFU/100â¯mL were recorded from reactors 1:1, 2:1, and the control, respectively. The total elimination of the fecal coliforms below the detection limit (<3 log 10â¯CFU/100â¯mL) was observed in both reactors after 15-17 days, whereas the number of fecal coliforms remained at 2.3â¯×â¯108â¯CFU/100â¯mL in the control reactor. The fecal coliforms were eliminated because of the acidification caused by the LAB during the incubation time. The final pH in the treatment reactors 1:1 and 2:1 was 3.7 and 3.9. While the final pH in the control reactor was 7.91. The results revealed that the bacterial pathogens in FS can be completely eliminated through a low-cost technique and a simple lactic acid fermentation process.
RESUMO
A simple and fast analytical method for the determination of Cr, Pb and Cd in brown sugar by GF AAS using slurry sampling was developed and in house validated for the first time. Analytical curves were prepared by external standardization for Cr, and by matrix simulation for Pb and Cd and they were linear. Low limits of quantification for Cr (32.8â¯ngâ¯g-1), Pb (49.3â¯ngâ¯g-1) and Cd (4.5â¯ngâ¯g-1) were found. Repeatability and intermediate precision estimates (<10% and <15%, respectively) and recovery rates (95-103%) demonstrated a good precision and accuracy. The levels in brown sugar samples ranged from <32.8 to 160â¯ngâ¯g-1 for Cr, from <49.3 to 211.0â¯ngâ¯g-1 for Pb and from <4.5 to 7.0â¯ngâ¯g-1 for Cd and they may be assigned to anthropogenic activities and the adoption of inadequate practices of production and processing.

ABSTRACT Objective To compare the effects of fermented kefir on the nutritional, physiological, and biochemical parameters of rats. Methods Grains of milk kefir (whole and skimmed) and water kefir (brown sugar) were used. The chemical composition analysis was performed on substrates and fermented beverages. The rats were evaluated for weight gain, body mass index, as well as their food, water, kefir, and calorie intake. We also evaluated their energy efficiency coefficient, weight of organs, in addition to their serum, and hepatic biochemistry. Results Fermentation increased the acid content index owing to degradation of lactose and brown sugar. The animals consumed more kefir, reducing the intake of chow and water. Kefir did not alter body and organ weight, while improving the lipid profile. Conclusion Water kefir with brown sugar was more effective in improving the lipid profile.

Grapholita molesta (Busck) is one of the main pests in apple crops in Brazil, where it is controlled by mating disruption (MD) with the use of the synthetic sex pheromone. However, sex-pheromone-based monitoring is not effective in MD-treated areas and may result in losses in production. This work has defined a trap model and a bait for luring G. molesta adults in MD apple orchards. The experiments were conducted in commercial apple orchards located in São Joaquim, SC, Brazil. Three trap models-McPhail, Pot, and Ajar-and three baits-grape juice (25%) (GJ), sugarcane molasses (25%) (SM), and a solution containing brown sugar (8.69%) and terpinyl acetate (0.05%) (TAS)-were assessed for luring G. molesta adults in areas subjected to the mating disruption. The assessments were performed weekly by collecting the insects caught in the traps. In addition, time needed to replace traps was also assessed, as well as the selectivity of the trap/bait set. In the laboratory, G. molesta adults were sexed, and the females were dissected to confirm reproductive status. We discuss our results and sugarcane molasses (25%) captured the least number of G. molesta adults regardless of the tested traps. The Ajar/TAS, Pot/TAS, and McPhail/GJ captured the largest number of G. molesta adults. The Ajar/TAS was the most selective and easier to handle. TAS was efficient in catching G. molesta until 14 days after preparation of the solution. Ajar/TAS has potential to be used in the monitoring of G. molesta in apple orchards.

In this study, 2 types of solidified noncentrifugal brown sugars (W-NCS and P-NCS) were prepared from the whole stalk and separated pith, respectively, of raw sugarcane (Saccharum officinarum L.). These products were discriminated in terms of their quality attributes, including color, sugars and minerals composition, taste, aroma, and antioxidant activity. The brown color of P-NCS was clearly different compared with that of W-NCS with a color difference value (ΔE* ) of 9.36. There was no difference in the sugars and minerals composition between the 2 types of sugar, which led to very similar taste profiles. However, P-NCS had a weaker aroma intensity than W-NCS did. Moreover, P-NCS retained more than 60% of the antioxidant activity of W-NCS. The information gleaned from this study might be used to select appropriate end-uses for these 2 types of sugars.
RESUMO
Recently the use of brown sugar has increased due to its nutritional characteristics, thus requiring a more rigid quality control. The development of a method for water content analysis in soft brown sugar is carried out for the first time by TG/DTA with application of different statistical tests. The results of the optimization study suggest that heating rates of 5°C min(-1) and an alumina sample holder improve the efficiency of the drying process. The validation study showed that thermo gravimetry presents good accuracy and precision for water content analysis in soft brown sugar samples. This technique offers advantages over other analytical methods as it does not use toxic and costly reagents or solvents, it does not need any sample preparation, and it allows the identification of the temperature at which water is completely eliminated in relation to other volatile degradation products. This is an important advantage over the official method (loss on drying).

The aim of the study was to determine the effect of different types of sugar on the formation of heterocyclic amines (HCA) in marinated grilled chicken. Chicken breast samples were marinated with table sugar, brown sugar, and honey for 24h at 4 °C. The internal temperature, weight loss, free amino acids, sugars, and HCA were determined. The concentrations of all types of HCA (except IQx) in samples that were marinated with table sugar were significantly higher (p<0.006) than brown sugar; whereas those were marinated with honey had the lowest HCA concentrations. A substantial reduction in the concentration of MeIQ, PhIP, DiMeIQx, IQ, IQx, and norharman was achieved in chicken marinated with honey. A correlation study indicated that adding honey into the recipe retarded the formation of most HCA (MeIQ, DiMeIQx, IQ, IQx, norharman, and harman), whereas table sugars enhanced the formation of all HCA except norharman, harman, and AαC.

Changes in the quality attributes of non-centrifugal cane brown sugar represented by physicochemical characteristics as well as flavour components and Maillard reaction products (MRPs) were monitored every 3 months over 1 year of storage. Stored cane brown sugar became darker, and its moisture content and water activity (a(w)) increased during storage. Fructose and glucose levels decreased as non-enzymatic browning via the Maillard reaction occurred in the stored sample, and a similar trend was also discovered in aconitic and acetic acids. Stored cane brown sugar lost its acidic and sulfuric odours (58.70-39.35% and 1.85-0.08%, respectively); subsequently, the nutty and roasted aroma increased from 26.52% to 38.59% due to the volatile MRPs. The browning rate of stored cane brown sugar was positively associated with the development of volatile MRPs (Pearson's coefficient = 0.860), whereas the amount of 3-deoxyglucosone, an intermediate product of the Maillard reaction, had a lower association with the brown colour due to its relatively slow degradation rate.
