The levels of lipid peroxides, determined as thiobarbituric acid reactive substances (TBARS), and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), were examined in the blood from stroke-prone spontaneously hypertensive rats (SHRSP), with and without cerebral lesions, and normotensive Wistar Kyoto (WK) rats. The levels of TBARS in the blood from healthy SHRSP wer...

BACKGROUND: Autoxidation is an irreversible reaction which occurs with the effect of oxygen in the air, and results in unpleasant taste and smell that are known as the signs of rancidity in oil. OBJECTIVES: In this study, the antioxidant potential of clove, summer savory and tarragon essential oils (EOs) in grape seed oil was evaluated. METHODS: Effects of EOs at different concentrations (0.3, ...

background: iron deficiency anemia is one of the major causes of morbidity and mortality worldwide. evidences from epidemiological and clinical studies suggest a possible correlation between antioxidant levels and the anemic disease risk. the present work is to investigate antioxidant levels and lipid peroxidation in anemic patients. methods: a number of 30 patients (15 males and 15 females) we...

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

The utilisation of Moringa oleifera leaves powder (MOLP) to improve the nutritional properties and inhibit lipid oxidation proliferation microorganisms in ground beef during cold storage was examined. effects 0.2, 0.4, 0.6, 0.8% MOLP on (proximate composition, total phenolic flavonoid content), thiobarbituric acid reactive substances (TBARS), microbial physicochemical characteristics (pH value,...

Moringa oleifera is a crop that has spread throughout the tropics worldwide and its seeds are non-conventional source of edible oil. The objective this study was to evaluate oxidative stability fatty acid profile M. oil under frying conditions for an extended time. Typical parameters used characterize assess quality oils were evaluated following standard methods such as saponification value. In...

Araştırmada, Trachystemon orientalis L.'nin (Kaldirik, Somar) sığır kıymasının raf ömrüne etkisi araştırılmıştır. Kurutulmuş L. yaprakları farklı solventler (petrol eter, metanol ve su) ile muamele edildikten sonra liyofilize edilmiştir. Liyofilize ekstraktlar kıymaya seviyelerde (250 ppm 500 ppm) ilave edilmiş kıyma örnekleri 2±1 °C'de aerobik olarak depolanmıştır. Depolamanın 1., 24., 48. 72....

The present research was conducted to measure the impact of poppy seed extract (PSE) and gamma irradiation on storage stability antioxidant profile beef patties during at different packaging. Different doses (2.5 kGy 5 kGy) were applied alone with combination 2% PSE. PSE enriched packed (aerobically vacuum) kept refrigeration temperature. results show that higher value TBARS POV found in aerobi...
