This study evaluates the effect of two contrasting years, in terms climatic parameters, on kernel morphology and content composition oil, tocopherols 11 macro- micro-elements almonds. Low precipitation high temperatures increased tocopherols, Cu Zn but decreased ratio, oil content, levels macro-elements Cr, Fe, Mn Mo. The obtained data indicate some statistically significant correlations among ...

Andean lupin (L. mutabilis) seeds, appreciated for their high protein and unsaturated lipid content, must undergo water debittering to eliminate alkaloids. The aim of this research was investigate the effects further technological treatments such as extrusion spray-drying (with two different coating agents, gum Arabic maltodextrin, at 6% w/w) on antioxidants three ecotypes. Tocopherols (mainly ...

Pumpkin ( cucurbita maxima ) belongs to cucurbitaceae which include pumpkin, gourds, melons and squashes. They are characterized by their seed oil. Pumpkin plant has been grown since the earliest history of mankind 1 . ( Brucher – 1989 ). Pumpkin are grown around the world for variety of agricultural purposes, the seeds show anti helmintic, taenicide diuretic, cardio tonic, anti-inflammatory, a...

The effect on induction period and tocopherol content after γ-irradiation on samples of olive oil and seed oils (sunflower and soybean) was determined. In seed oil samples 0, 100, 200 and 300 ppm of δ-tocopherol were added before irradiation with 1, 2 and 3kGy. The results of induction period showed that, after irradiation, all samples presented a significant decreased in resistance to oxidatio...

Methods were developed for the separation, detection, and quantification of tocopherols and phytosterols by high-performance liquid chromatography with an evaporative light-scattering detector. Four tocopherolsa, fJ, y and o-and four phytosterols-campesterol, fJ-sitosterol, brassicasterol, and stigmasterol-were analyzed in soybean, sunflower, low-erucic acid rapeseed (LEAR) and com oils. The us...

Antioxidants such as tocotrienols may protect against atherosclerosis since tissue injury from free radicals is a final common pathway of damage in arterial disease. In this study, the effects of tocotrienols on serum cholesterol, lipid peroxides, and aorta atheroma were assessed in rabbits fed an atherogenic diet for 12 weeks. Tocotrienols were more effective than tocopherols in preventing inc...

The antioxidant activities of natural d-alpha-tocopherol, mixed tocopherols and tocotrienols, and formulations comprising all forms of vitamin E, providing 400 IU, were determined employing an improved oxygen radical absorbance capacity (ORAC) assay using fluorescein (FL) as the fluorescent probe, randomly methylated beta-cyclodextrin (RMCD), 2,2'-azobis(2-amidino-propane)dihydrochloride (AAPH)...
