DOSTÁLOVÁ J., HANZLÍK P., RÉBLOVÁ Z., POKORNÝ J. (2005): Oxidative changes of vegetable oils during microwave heating. Czech J. Food Sci., 23: 230–239. The oxidative stabilities of pork lard, sunflower, zero-erucic rapeseed, peanut and high-oleic peanut oils were tested under microwave heating conditions. Vegetable oils and lard were heated in a microwave oven for up to 40 min between 25°C and ...

This study investigated some quality attributes of the functional properties turmeric rhizome flour cultived in Côte d’Ivoire. It consisted comparing powder with film (PWF) and without (PWAF) to identify nutritionally technologically appropriate uses. In terms properties, PWAF had best water absorption rates (1032.156 ± 34.016%), stability (74.3%), solubility index (19.50%) very good wettabilit...

Brassicaceae vegetables, among them broccoli and Chinese cabbage, are well recognized due to the nutritional properties. Four-week-old Chinese cabbage and broccoli seedlings were fumigated with O3 for 3 days before being transplanted into the field. The effect of O3 treatment was determined after reaching marketable quality (ca. 10 weeks). The inflorescences of O3-treated broccoli were enriched...

Fruit seed oils are of new interest due to their significant properties and can be a good opportunity recover fruit waste. Actinidia arguta (baby kiwi) fruits novelty in the market berries consumed with peels. Due limited shelf life, very perishable waste management techniques used post-harvest an important issue. Berry reused, for biological flows focused on food losses reduction. Therefore, b...

Extraction of vitamin E from human milk, by use of hexane, with and without prior saponification, was compared. Analysis of milk extracts was performed by HPLC with a C18 column and UV detection. With both methods a significant relationship (P < 0.01) was obtained between levels of α-tocopherol and γ-tocopherol in human milk, although saponification resulted in higher and more consistent recove...

According to the European Food Safety Authority, currently, there are no reliable data or robust guidelines available in relation to the micronutrient composition of infant foods. This study evaluated the intake of vitamins A and E of infants from 'ready-to-feed' foods and formulas. Normal phase high performance liquid chromatography was employed for simultaneous quantification of retinyl aceta...

Background. The Free Radical Theory of Aging mechanistically links oxidative stress to aging. Okinawa has among the world's longest-lived populations but oxidative stress in this population has not been well characterized. Methods. We compared plasma lipid peroxide (LPO) and vitamin E-plasma and intracellular tocopherol levels (total α, β, and γ), in centenarians with younger controls. Results....
