PURPOSE Plant sterols and stanols interfere with intestinal cholesterol absorption, and it has been questioned whether absorption and plasma concentrations of fat-soluble vitamins and carotenoids are also affected. We conducted a meta-analysis to assess the effects of plant sterol and stanol consumption on plasma fat-soluble vitamin and carotenoid concentrations. METHODS Forty-one randomized ...

This work evaluated the enzymatic and non-enzymatic antioxidant defense systems of avocados cv. Hass stored at 7 ± 0.5 °C for 10, 20, 30 d, stage edible ripeness. The enzyme system included superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), was composed total phenolic compounds (TPC), carotenoids (TC), α-, β-, γ-tocopherols, as well hydrophilic (H-AOX) lipophilic (L-AOX) activities. ...

The present investigation has been carried out to determine the proximate composition, amino acids, metal contents, oil composition as well as the antioxidant capacity of the seeds of Ipomoea hederacea Jacq. and Lepidium sativum L. Proximate composition indicated a great difference in oil (14.09 ± 0.66, 28.03 ± 1.05) and fibre (16.55 ± 0.31, 6.75 ± 1.20) contents for I. hederacea and L. sativum...

The present work was intended to analyse the chemical composition and oxidative stability of the muscle biceps femoris and adipose tissues from Iberian pigs fed different finishing diets: free-range feeding on grass and acorns in a 'Montanera' traditional system (MON), fed in confinement with a mixed diet containing high-oleic sunflower oil (115 g/kg of diet) and supplemented with 250 mg/kg α-t...

Apples are one of the most popular crops in world, grown for fresh consumption, processing, and ornamental purposes. In present study, seeds thirty crab apple (Malus spp.) genotypes were analyzed to evaluate tocopherol composition find a crop-specific profile. The mean proportion (%) (T) homologues (α, β, γ, δ) was as follows: α-T (45.8%), β-T (21.8%), γ-T (24.3%), δ-T (8.1%) with content 22.41...
