Rice bran oil, non conventional oil was blended with six traditional oils in the ratio of 70:30 and 80:20 for the enhancement of its market acceptability and awareness in consumers regarding its use in cooking. Effect of deep-fat frying on these blends was studied by assessing the changes in percent fat absorption and physicochemical properties during repeated frying process (three times). The ...

world consumption of butter has declined over the last decades partly due to its physical limitations and partly due to its poor nutritionalproperties. in this study, the effect of hazelnut addition on the properties of butter, was evaluated taking into account that hazelnut is a source of unsaturated fatty acids and antioxidants. powdered hazelnut was added to butter at 3 levels (10, 20 and 30...

in this project, different nettle plants from north regions of iran including tonekabon, amol and gorgan were collected. the oil was extracted using soxhlet extraction apparatus and was subjected to series of physical and chemical tests and determinations consisting of refractive index, melting point, smoke point, nonsaponifiable matter, iodine value, saponification value, peroxide value, totox...

Virgin coconut oil (VCO) has been widely used traditionally in Malaysia as moisturiser and food supplement. Recently, VCO has been growing in popularity because of its better chemical and biological properties compared to coconut oil. VCO contains medium chain fatty acids of which 4550% lauric acid. Lauric acid has been proven to become a strong anti-inflammatory and anti-microbial agent. In th...

Hydrogenation of oils might be considered as the largest reaction in the edible oil industry. The reaction consists of the addition of hydrogen at the double bounds of fatty acids. Although for some reasons this might be considered a desirable reaction but for some others it might create problems in the food and nutrition chain circle due to the formation of saturated and trans fatty acids. Soy...

The objective of the research was to determine the optimum application rates of soybean peroxidase (SBP) plus peroxide (SBPP) for reducing odorous VOC emissions from swine manure. Industrial-grade SBP was applied in combination with liquid hydrogen peroxide (H(2)O(2)) or powdered calcium peroxide (CaO(2)) to standard phenolic solutions and swine manure, and emissions were measured in a wind tun...

A modified cytochrome c peroxidase was prepared by reconstituting apocytochrome c peroxidase with protoheme in which both heme propionic acid groups were converted to the methyl ester derivatives. The modified enzyme reacted with hydrogen peroxide with a rate constant of (1.3 +/- 0.2) x 10(7) M-1 s-1, which is 28% that of the native enzyme. The reaction between the modified enzyme and hydrogen ...

Camellia oil is a kind of natural product with high added value. In the process production, processing, and transportation, acidic substances peroxides that reduce quality are produced. this paper, it was refined by scraping membrane molecular distillation device. The factors affecting results were analyzed studied through single factor experiment orthogonal experiment. On surface experiment, o...

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...
