Chia seeds (Salvia hispanica L.): A therapeutic weapon in metabolic disorders.

The growth of functional components containing agricultural foods is enhancing because these components aid the human body against different chronic diseases. Currently, chia seeds basically belong to the mint family and are edible seeds of Salvia hispanica. These seeds are composed of different functional components including fiber, polyphenols, antioxidants, omega-3 fatty acid vitamins, minerals, and peptides. Besides, these seeds are also a good source of vegetable protein, unsaturated fat, carbohydrates, and ash. Chia seed components are helpful in cardiovascular disease (CVD) by reducing blood pressure, platelet aggregation, cholesterol, and oxidation. In GI-tract-related diseases like diabetes and constipation, chia fiber reduces the blood glucose level and provides bulk to stool. However, antioxidants and polyphenols are protected beta cells of the pancreas from inflammation. These components are protected from the cell damage of the different body parts, which can provide help in different types of cancer including breast, colorectal, liver, and pancreatic. Conclusively, some pervious studies approved that chia seed components are played important role in chronic diseases.

Effect of milk-derived bioactive peptides on the lipid stability and functional properties of beef nuggets.

The present study was conducted to ascertain the beneficial effects of bioactive peptides on the oxidative stability and functional properties of beef nuggets. In this study, milk casein protein hydrolysates were extracted and incorporated into beef nuggets which were then subjected to different assessment parameters including oxidative stability, functional capability as well as microbial and physico-chemical quality tests were performed for determining the meat quality at different storage periods. The casein protein hydrolysate powder (CPH) was added at different concentrations in nuggets CPH 2%, 4%, 6% and 8%, with reference to storage period of 0, 5, 10 and 15 days at 4 °C. The results regarding total phenolic contents (TPC) and DPPH free radical scavenging assay showed a significant increased with respect to CPH powder and significantly decreased with respect to storage interval. The TVBN, TBARS and POV of the CPH powder incorporated raw beef nuggets also differed significantly within groups with storage time. Higher POV and TBARS were noticed in the CPH 8% incorporated beef nuggets. However, the raw beef nuggets that were made by the incorporation 8% CPH powder, maintained significantly lower level of TBARS at the end of the storage period in contrast with the levels of the control (CPH 0%). The results of the pH and Hunter color test also showed a significant difference with respect to different groups. The microbiological analysis of beef nuggets showed a significant decrease in the level of both the total aerobic and coliform counts and also indicated a decreasing trend in the level of contamination by these bacteria within the groups. This depicted that the casein protein hydrolysate powder (CPH) or simply, the peptide powder has the strong ability to decrease lipid oxidation and related shelf-life retarding natural processes occurring in the meat. It can also greatly enhance the functional properties of the raw meat (beef) and meat products. Thus, it is seen that the bioactive peptides (BAP's) are a key factor in improving the oxidative stability and functional properties of beef nuggets.

Structural and nutritional portrayal of rye-supplemented bread using fourier transform infrared spectroscopy and scanning electron microscopy.

In the present study, four different variants, namely Gp-1, Gp-2, Gp-3, and Gp-4, were characterized for their nutritional and fatty acid profile. Later on, the nutritionally superior variant was used for bread preparation. Purposely, composite flour was prepared with different ratios of wheat and rye (100:0; 90:10; 80:20). Furthermore, structural characterization of bread was done using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Results showed that the Gp-2 was more nutritional among the four variants. Furthermore, the spectra of composite flour bread were scanned in the range of 4000-600 cm-1. All the bread samples presented almost similar spectra for major peaks corresponding to wavenumbers in the functional group. The SEM micrographs showed the presence of small and large starch particles with compact structures. Conclusively, rye flour supplementation has a significant impact on the nutritional and structural attributes of the bread.

Exploring the prophylactic role of soy isoflavones against polycystic ovarian syndrome.

Soy isoflavones (SI) have strong estrogenic effect in tissues by binding to estrogen receptors and might be beneficial for women with polycystic ovarian syndrome (PCOS) by reduction in testosterone, cholesterol, insulin, weight gain, inflammatory markers, and oxidative stress. The study was planned to examine the effect of various levels of SI on nutrient intake, digestibility, lipid profile, insulin, and reproductive hormones of estradiol valerate (4 mg/rat/IM) PCOS induced rat models. Thirty-six Wistar 45 days old rats weighing 95 ± 5 g were divided into 4 groups, each having 9 rats: C (control: without SF), SF10 (SF 0.10 g/kg BW), SF15 (SF 0.15 g/kg BW), and SF20 (SF 0.20 g/kg BW). SF was given through the oral gavage. Food and water were offered ad libitum, and intake was recorded daily. During last week of trial, collected feces by total collection method and blood samples were used to calculate nutrient digestibility and biochemical analysis, respectively. Estrogen, progesterone, and prolactin were (p < .05) high in rats fed SF diet that was 4% and 30% increase from C, respectively. Insulin, testosterone, FSH, and LH were lowest in rats fed diet SF20. Significant (p < .05) reduction in cholesterol was observed in rats fed SF15 and SF20 as compared to C. Serum HDL was improved (p < .05) in all SIF0.10, SIF0.15, and SIF0.20 in comparison with PC. Serum LDL was significantly reduced to 68.89 ± 4.36 (mg/dl) in SIF0.20 and to 108.20 ± 4.14 (mg/dl) in SIF0.15, whereas insignificant reduction was observed in SIF0.10 as compared to PC. Highly significant reduction was noted in triglycerides level in SIF0.20; however, significant reduction was observed in both SIF0.10 and SIF0.15 as compared to PC after 3 months of treatment with soy isoflavones.

Nutritional and end-use perspectives of sprouted grains: A comprehensive review.

Scientific literature is evident that the germinated seeds possess a promising potential for essential nutrients, flavors, and textural attributes over nongerminated grain. In recent decades, sprouting has also been investigated as a potential green food engineering technique to boost the nutritive profile of grains. Sprouting grains have multifold applications in different fields such as baking, pharmaceutical, and cosmetic industries. During sprouting, shifting of molecular structures to macroscopic takes place. Sprouting reactivates the grain metabolism which leads to the catabolism and degradation of antinutrient and macronutrient compounds. These modifications have an effect on human health and on the nutritional content of the foodstuffs. Sprouting grains have high bioactivity against diabetes and cancer. Germination is also an outstanding green food development technique to increase the seed nutritive profile in terms of quality. The present review focuses on the sprouting of grains, changes in nutritional profile, and the technological exploration of sprouted grains.

Comparative study of innovative blends prepared by fortification of date powder to alleviate child malnutrition.

Child malnutrition is one of the biggest problems in developing countries with higher level of food insecurity. Pakistan is 5th largest producer of date fruit; therefore, its processing and products should be explored in various dimensions. Being rich source of minerals and sugars, it can contribute in weaning foods in a good manner. In current study, three blends were prepared with specific proportions of spray-dried date powder and rich in specific proportions. They were compared with each other and control (free of date powder). The nutritional profile of the formulations revealed that 100 g of each formulation included all macronutrients in compliance with the requirements of Food and Agriculture Organization for weaning formulations; moreover, they are enriched with minerals due to presence of date powder. The iron contents reached up to 12.74 ± 0.16 mg/100 g. The phosphorus, zinc, and potassium contents also increased with the increase in date powder subsequently. Physicochemical properties exhibited in compliance with the requirement of the weaning foods. The protein quality was assessed both in vivo and in vitro. Amino acid profiling indicated that the limiting amino acid in F1 and control were lysine but in F2 and F3 were threonine. This is suggested that date powder might contain good quality protein that was further explained in biological studies, the formulations that contained higher amount of date powder reveled better PDCAAS score 86.76 ± 4.5, true digestibility 84 ± 4.36, biological value 69.45 ± 0.69, net protein utilization 73.82 ± 1.46, and protein efficiency score 1.18 ± 0.07. The sensory evaluation revealed that F2 showed better result in overall acceptability. Thus, date powder is suggested to be used as good constituent that can fortify mineral contents and sugar contents of the weaning foods.

Comparative study of chemical treatments in combination with extrusion for the partial conversion of wheat and sorghum insoluble fiber into soluble.

Dietary fiber has gained greater attention owing to their positive and potential health perspectives. Cereals are the most important and enriched source of dietary fiber with more insoluble dietary fiber than soluble. For dietary fiber modification, chemical treatment with various techniques is considered as significant approach owing to its safety point of view and involves less damage to the molecular structure of the dietary fiber through chemical reagents and content of soluble dietary fiber is increased more efficiently. The current study was aimed to nutritionally characterize the cereal grains and to partially convert insoluble dietary fiber into soluble dietary fiber through chemical treatments in combination with extrusion. For the purpose, two varieties of each cereal were characterized for their chemical composition, mineral profile, and dietary fiber content according to the respective methods. Then, dietary fiber ratio in cereals was modified through chemical treatments, that is, acid, alkaline, and consecutive acid-alkaline followed by extrusion. Results regarding dietary fiber content of cereal grains exhibited that wheat (12.03-12.20 g/100 g) contained higher total dietary fiber followed by sorghum (6.70-6.90 g/100 g). Additionally, modification of SDF (1.97%) and IDF (11.48%) ratio in wheat and SDF (1.19%) and IDF (24.25%) ratio in sorghum through extrusion processing was nonsignificant while acid-alkaline treatment showed highly significant results, that is, 768.2% increase in SDF and 56.5% decrease in IDF in wheat and 952.38% increase in SDF and 71.17% decrease in IDF in sorghum. Among chemical treatments, higher result was given by acid-alkaline method and the lower outputs were observed in case of extrusion in both cereals. Conclusively, soluble dietary fiber was significantly increased through chemical treatments alone or in combination with twin-screw extrusion.
