The recorded minimum and maximum PV were 3.9 and 15.4 meq KOH/kg oil, while FA was 0.12 and 0.82% as oleic acid, respectively. The PV and FA increased during storage for 5 weeks. The iodine value of the sesame seeds oil decreases as it was roasted over a period of storage. This suggests the loss of unsaturation in the fatty acids of the triacylglycerols. The antioxidant factors responsible for the stability of roasted sesame seeds is highly affected by the conditions of the roasting process. Spectrophotometric methods for determination of polyphenolic contents; Total reduction activity by Fe-Fe transformation; Hydrogen peroxide scavenging activity for total antioxidant activity were used before 3+ 2+ and after different roasting processes.

L-4076, L-4594, L-4147, DPL 15, DPL 62, and IPL 406. Three solvents, 70% ethanol, 100% methanol and 80% acetone, were used for preparation of seed extract. The seed extract was tested for total phenolic content, total flavonoid content and antioxidant activity by FRAP assay. The results showed that values for TPC, TFC and FRAP assay were greatly influenced by the type of organic solvent used and the genotype. The total phenolic content ranged from 272 -14.7 mg GAE/g, total flavonoid content 7.57-0.72 mg QE/g and FRAP 9.32-0.79 mMol Fe/g. Amongst all the cultivars tested, DPL-62 and IPL 406 exhibited high phenolic content as well as antioxidant activity which were higher than previously reported for lentils. The most efficient solvent for total phenolic extraction and antioxidant activity evaluation was 80% acetone, whereas 100% methanol and 80% acetone both showed similar results for flavon...

The members of Brassicaceae are devoured by natives throughout the world. They comprise important food crops in Europe, Japan, China and India and thus symbolize a vital portion of human regimen worldwide. Brassica vegetables frequently exploited for food include broccoli, cauliflower, Brussels sprouts, cabbage and certain seeds. They are important source of bioactive compounds and nutrients like Vitamin E and C, soluble fiber, enzymes owing antioxidant activity for example peroxidase, superoxide dismutase (SOD) and catalase and carotenoids which have persuasive antiviral, antibacterial and anticancer activity. Brassica vegetables have positive impacts on human vigour which are somewhat accredited to their composite blend of phytochemicals possessing antioxidant activity that fights against free radicals by acting on complementary and transformed levels. They basically lead to the...
