An herbal supplement made with thyme, mint, cilantro, and rowan and viburnum fruit has been used to fortify wheat bread with antioxidants. The antioxidant activity of raw materials and bread was determined by the spectrophotometric method. To determine substances with antioxidant properties, the HPLC method was used. The chromatogram of the alcoholic extract of the herbal supplement showed that the supplement contains organic acids, flavonoids and anthocyanins. The HPLC method was used to determine the amount of flavonoids in the supplement and bread. Micrographs of the surface of slices of bread with a phytonutrient were obtained by scanning electron microscopy. The presence of chemical elements with antioxidant properties was determined using an X-ray EMF detector in the scanning electron microscope system. The use of phytonutrients in bread technology has been found to lead to an increase in the quality of the product and its antioxidant activity. [ABSTRACT FROM AUTHOR]

This research investigated the combined effects of cooking methods (household griddle (C1), household conventional oven (C2), industrial oven (C3), storage temperature (refrigeration /freezing) and packaging system (aerobic and vacuum), on quality of chicken burgers. The results show that refrigeration storage favours the retention of moisture content and the juiciness of chicken burgers, but the application of vacuum (RV) was the best option to maintain the juiciness and moisture content (p < 0.05) of the samples prepared in an industrial oven with forced-air convection. The highest protein content was observed in the samples that were frozen in vacuum packaging (FV), and the lipid content was highest in the samples chilled in conventional packaging (RC) at 1 atm. Regardless of the cooking method used and the internal pressure of the packages (≤ 1 atm), refrigerated storage contributed to the best scores (p < 0.05) for color and flavor attributes. The treatments that presented the highest sensory acceptance index were the frozen samples in vacuum packaging prepared in the industrial oven, conventional oven, and grill (90%, 82.66%, and 74.33%, respectively).

Oxidative stability and fatty acid composition of the pumpkin seed oil (PSO) were studied, during roasting process from 80 to 150 °C and oil heat treatment (220 °C), by FTIR (Fourier - transform infrared)-- Spectroscopy and GC/MS (Gas chromatography - mass spectrometry). The physicochemical parameters (density and iodine value) showed a significant increase (p < 0.05) during roasting, with a maximum value observed in the oil roasted at temperatures from 90 to 110 °C. The relative contents of polyunsaturated fatty acids (PUFAs) decreased to 87.7%, and saturated fatty acids (SFAs) increased to 112.5% at unroasted sample, after thermal treatment of oil samples. Especially at temperature 90 and 110 °C, oil samples have demonstrated that relative contents of PUFAs decreased to 95 % and SFAs increased to 101.6%. FTIR Spectroscopy provide to understand mechanism of chemical changes of seed during roasting process and, as result, which of obtained compounds are responsible for increasing thermal stability of oil lipids. In this study, it was observed that the best temperature for roasting pumpkin seeds is 110 °C, since at this point, both oxidation and Maillard reactions give rise to compounds with maximum antioxidant effect (lipid stability).

The quality of bread produced from wheat, cashew nut flour and pro-vitamin –A- cassava flour blends were evaluated. Pro-vitamin -A - cassava flour and Cashew nut flour were prepared. Wheat, pro-vitamin A cassava flour and cashew nut flour were made into blends ration of 100%:0%:0% sample A, 90%:5%:5% sample B, 80%:15%:5% sample C, 85%:10%:5% Sample D and sample E, 75% 20%:5% respectively. Result analysis revealed increase in physiochemical properties as blending increased. The moisture content, Protein content, Fat content, Carbohydrate and Pro-vitamin A contents increased constantly with increase in blending. The oil absorption capacity decreased with blending. Other functional properties such as Water absorption capacity, Bulk density, swelling index, loaf height, and loaf volume increased as blends ration increases. Sensory characteristic reflected a down turn progression as blending was increased. Increase in cashew nut flour led to increase in chemical and functional quality values of the bread samples hence cheap bio functional ingredient which could also alleviate hidden hunger in rural populations with supplies of macro and micro nutrients.

Main aim of this study was to evaluate hypocholesterolemic potential of microwave-assisted black cumin (Nigella sativa) extracts (MABCEs) in a rat bioassay. Efficacy trial in this study comprised of 25 male albino rats which were divided into 5 groups having 5 rats each. Out of these 25 rats, 20 were hypercholesterolemic and 5 were normal rats. Hypercholesterolemia was induced by providing high cholesterol diet for 15 days, and after the onset of hypercholesterolemia these rats were administered with different concentrations of the MABCE i.e. 150, 300 & 450 mg/kg B.W. for a period of 28 days. The administration of extract displayed significant lowering in the lipid profile of the experimental rats. The 300mg/kg B.W. dose of black cumin MAE provided the optimum results giving cholesterol, triglyceride and LDL-c content lowered by 14.9%, 11.32% and 12% and value of HDL-c elevated by 12.88% compared to the hypercholesterolemic control. Similarly, there was a percent elevation in levels of SOD and CAT by 19.83% and 13.97%. The current study concluded that MABCEs have hypocholesterolemic effect thus can be used for its therapeutic property. [ABSTRACT FROM AUTHOR]

The study was conducted to investigate the hypolipidemic properties of Microwave assisted extracts (MAE) obtained from different parts (whole fruit, leaves, seeds and roots) of Citrullus colocynthis on hyperlipidemic experimental rats. The trial consisted of 30 male rats that were divided into six groups each having 5 rats whereas, out of these 25 were hyperlipidemic and 5 were normal rats. After the induction of high cholesterol for 15 days, 20 rats were fed with microwave assisted extract of different parts at a concentration of 200mg/kg/B. W for 28 days. The administration of the extracts reported considerable reduction in the lipid profile parameters of the hypercholesterolemic rats.

Soybean an amusing source of protein, oil, carbohydrates and bioactive moieties make it functional to combat hypercholesterolemia, hyperglycemia, age related bone loss, hormone replacement therapy and anti- cancer. Fermentation is considered as a pragmatic approach to augment bioactive moieties and to eliminate anti-nutritional components in soy bean. The current research was done to compare fermented and non-fermented soy milk by estimating their physicochemical analyses (Fat, protein, ash, SNF, TSS) pH, acidity, antioxidant (DPPH, ABTS and FRAP), rheology and isoflavones content (Genistein and Daidzein). The resultant data justify that process of fermentation boost up antioxidant profile, bioactive moieties becomes more viable and rheological analysis stated that soy milk is non-Newtonian fluid and fermentation increases the viscosity of soy milk by making gel network with LAB and protein. The sensory evaluation also justifies the hypothesis of current research by getting bountiful higher score to fermented soy milk for (color, flavor, aroma, texture and overall acceptability).
