g-oryzanol is one of the strongest antioxidants. it inhibits oxidation and is only present in rice bran. this composition decrease cholesterol, which decreases the risk of atherosclerosis. ther prestn study extracted antioxidant from two varieties of rice bran (zayandeh rood and sazandegi) using methanol solvent and percolation. the extracts were added to edible oil without antioxidants in 100 ...

the oxidative stability of margarine supplemented with different concentrations of fennel (foeniculum vulgare) seed extract (fse) was compared to the synthetic antioxidants; butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) at legal concentrations. the experiment was carried out under accelerated storage conditions for 4 weeks employing peroxide value (pv), p-anisidine value (av...

Smen is a milk fat isolated by ‘boiling-off’ water. Milk fat was first converted into butter and then into smen. Smen product is utilized for culinary cooking and frying of different food. Smen has better shelf-life than other indigenous dairy products due to its lower moisture content. However, it undergoes deterioration (lipolysis and oxidation of milk fat) causes flavor impairment, lowers nu...

nowadays, the use of natural antioxidants as alternative antioxidants is more acceptable than synthetic antioxidants mainly for negative effects such as carcinogenicity and toxicity. this has led to an increasing interest in the search for natural antioxidants. the objectives of this study were to measure total crude phenolic compounds and in sorghum grain as natural antioxidant sources, to det...

In a study with male broiler chickens the impact of dietary oregano essential oil on performance data and on the susceptibility of abdominal fat, fresh and stored breast muscle tissue to lipid oxidation was examined. Four diets supplemented either with oregano essential oil in two levels (22.5 mg (OL) and 90 (OH) mg kg feed ), 40 mg α-tocopheryl acetate (VE) or without these additives (NC) were...

A two-year survey in 18 representative groves of a north Italian olive district sampled cvs. ‘Casaliva’ and ‘Leccino’ for single-site oils. Polyphenols had a major role in determining oil autoxidation stability with respect to tocopherols, even if the higher autoxidation stability of ‘Leccino’ over ‘Casaliva’ was probably due to the more than double content in tocopherols, which was significant...
