Aflatoxin, a mycotoxin found commonly in maize and peanuts worldwide, is associated with liver cancer, acute toxicosis, and growth impairment in humans and animals. In Tanzania, sunflower seeds are a source of snacks, cooking oil, and animal feed. These seeds are a potential source of aflatoxin contamination. However, reports on aflatoxin contamination in sunflower seeds and cakes are scarce. T...

Modifications of the fatty acid composition of plant vegetative tissues produce deficient plant growth. To determine the expression of the seed high-saturated sunflower (Helianthus annuus L.) mutant character during the vegetative cycle, five sunflower mutant lines (three high-stearic and two high-palmitic) have been studied during their germination and vegetative cycle. No significant variatio...

tea and sesame seed oils extracted by different methods (including supercritical fluid extraction (sfe), at a pressure of 350 atm, a temperature of 60oc, a static extraction time of 20 minutes, a dynamic extraction time of 30 minutes and 150 g kg-1 of ethanol as a modifier). solvent (se) and ultrasound-assisted solvent extraction (ue)), as natural anti-oxidants, were evaluated during 15 days st...

abstract: degumming and neutralization processes are two essential stages carried out on crude edible oils in order to remove some unwanted impurities namely gums and free fatty acids. in this research study two popular less expensive commercial oils that are consumed to a great extent namely soyabean and sunflower seed oils are selected and subjected to both degumming and neutralization proces...

Field control failures with pirimiphos-methyl against the rice moth, Corcyra cephalonica (Stainton), in Weslaco, Texas, USA, led us to investigate the susceptibility of this particular strain to pirimiphos-methyl, spinosad, pyrethrins synergized with piperonyl butoxide, and pirimiphos-methyl combined with synergized pyrethrins. In laboratory bioassays, 50 eggs of C cephalonica were exposed to u...

in this study nine new varieties of sunflower seeds were obtained and subjected to oil extraction using soxhlet apparatus. the extracted oil was analyzed for fatty acid composition and phosphorus content to measure the phospholipid concentration. the results indicated that armavirski variety had the highest oil content. the fatty acid composition of the extracted oils indicated that armavirski ...

bleaching process is an essential stage in the refining of vegetable oils and fats. in this process the colour and the primary and secondary oxidation products are removed by the treatment with the acid activated bleaching earth .the aim of this project is to understand the effect of bleaching on the physical characteristics and chemical constituents of neutralized canola and sunflower seed oil...
