The antioxidant’s ability of mushroom extract (prepared from edible mushroom -Pleurotus) to stabilize color of uncooked andcooked burger was evaluated in comparison to certain types of antioxidants (α-TOC / BHA ). The result showed that the lipid oxidation and color shelf life of uncooked and cooked burger upon addition of 2, 5 and 8 ml of mushroom extract (ME) per 100 g of meat, caused a prolo...

Antioxidants can inhibit atherosclerosis, but it is unclear how inhibition of intimal lipid oxidation relates to atherogenesis. Here we tested the effect of probucol and its metabolite bisphenol on aortic lipid (per)oxidation and atherogenesis in Watanabe heritable hyperlipidemic (WHHL) rabbits. LDL and aortas from rabbits fed probucol contained bisphenol at concentrations comparable to those i...

This study explored the effects of the antioxidant astaxanthin on paraoxonase and thioredoxin reductase activities as well as on other oxidative stress parameters and on the lipid profile in hypercholesterolemic rabbits. Rabbits were fed a standard or a hypercholesterolemic diet alone or supplemented with 50, 100 and 500 mg/100 g of astaxanthin for 60 days. Antioxidant enzymes activities, lipid...

This study was performed to investigate the effectiveness of grape seed extract (GSE) compared to butylated hydroxytoluene (BHT) on retarding lipid oxidation of sunflower oil subjected to convection and microwave heating up to 240 min under simulated frying conditions. The progress of lipid oxidation was assessed in terms of peroxide value (PV), p-anisidine value (p-AV), conjugated dienes and t...

The reaction of oxygen with unsaturated lipids produces a wide range of compounds that have attracted considerable interest and research. In foods, lipid oxidation products are responsible for the development of rancidity by the production of low molecular weight fission compounds that impart undesirable flavors. Potentially toxic and harmful cyclic and higher molecular weight materials are for...

High-density lipoprotein (HDL) has been proposed as the principal carrier of hydroperoxides in plasma, based upon data gathered with an HPLC-chemiluminescence technique. To test this hypothesis we have measured total lipid hydroperoxides in native plasma using the ferrous oxidation in Xylenol Orange (FOX) assay and then fractionated plasma into very-low-density lipoprotein (LDL) and HDL fractio...

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...

Fatty acids are known to decrease insulin-mediated glucose utilization in humans, both at rest and during exercise. To evaluate the effect of endurance training in this process, we infused lipids or saline in groups of sedentary and highly trained subjects. Whole body glucose utilization and substrate oxidation were monitored during a 2.5-h hyperinsulinemic clamp. During the last 30 min, a cycl...

This study was designed to evaluate the effects of dietary treatment, packaging, and irradiation singly or in combination on the oxidative stability of broiler chicken thigh meat. A total of 120 four-week-old chickens were divided into 12 pens (10 birds/pen), and 4 pens of broilers were randomly assigned to a control oxidized diet (5% oxidized oil) or an antioxidant-added diet [500 IU of vitami...

the aim of this study was evaluation of phytochemical components, antioxidant activity, and antibacterial effects of basil (ocimum basilicum l.) essential oil (beo) in vitro. the lipid oxidation of the meat and antibacterial effects of beo were also evaluated in beef burger product. in this empirical study, essential oil of the basil was isolated by hydrodistillation. then, beo was analyzed by ...
