Sacha inchi (Plukenetia volubilis) oil (SI) is appreciated for its nutritional and sensorial characteristics. The aim of this study was to evaluate SI changes during French fries deep-frying at 170 °C or 180 up 119 50 min, respectively; commercial soybean (SO) tested as control. had high ?-linolenic acid (53.8%), linoleic (33.4%) total tocopherols (2540.1 mg/kg). During frying tocopherol conten...

In this study, we asked the question “does -tocopherol supplementation prevent an increase in total plasma cholesterol (TPC) concentration and reduce the deposition of cholesterol in arterial plaques of rabbits fed atherogenic diets?” Isocaloric diets containing 0.1% cholesterol to induce atherosclerosis were enriched in one of three fats: saturated fats (SAT), monounsaturated fats (MONO), or n...

BACKGROUND Evidence that vitamin E may preserve cognitive function in elderly subjects is conflicting. The most abundant and most investigated form of vitamin E in humans is alpha-tocopherol, but other antioxidant tocopherols (beta, gamma, and delta) exist in nature. OBJECTIVE We aimed to investigate plasma concentrations of the natural tocopherols and the tocopherol oxidation markers alpha-t...

one of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. this study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

Abstract A three-year (2016–2018) open field experiment was conducted to study the effect of irrigation, fertilisation, and seasonal variation on main bioactive components, such as carotenoids (lycopene β-carotene), total polyphenols, antioxidant capacity, tocopherols processed Uno Rosso F1 tomato. The statistical evaluation measurements proved that multi-year data set cannot be evaluated combi...

Objectives: Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. Materials and Methods: Pheno...

noise induced hearing loss (nihl) is one of the most important occupational disease worldwide. nihl has been found potentiate by simultaneous carbon monoxide (co) exposure. free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the co hypoxia. this study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

The aim of the study was to reveal relationship between parameters actual nutrition and lipid peroxidation antioxidant defense system in adolescents aged 14–17 a rural area. Material methods. 76 Irkutsk region were examined by cross-sectional method. Actual studied 24-hour reproduction content substrates with unsaturated double bonds (DB), diene conjugates (DC), ketodienes conjugated trienes (K...

Individual plasma carotenoids have been associated with various chronic diseases but little is known about the relationship between total plasma carotenoids and risk factors for chronic diseases. In the Physicians' Health Study, we examined 492 men free of CVD and cancer for the relationship between total plasma carotenoids (the sum of alpha-carotene, beta-carotene, lycopene, zeaxanthin, lutein...

gamma-Tocopherol, the major form of dietary vitamin E, is absorbed in the intestine and is secreted in chylomicrons, which are then transferred to liver lysosomes. Most gamma-tocopherol is transferred to liver microsomes and is catabolized by cytochrome p450. Due to the hydrophobicity of gamma-tocopherol, a binding and transfer protein is plausible, but none have yet been isolated and character...
