In order to study the mechanism by which increasing unsaturation of dietary fat lowers HDL-cholesterol levels, we studied various measures of HDL metabolism in hamsters fed with fats with different degrees of saturation. Hamsters were fed on a cholesterol-enriched (1 g/kg) semipurified diet containing 200 g/kg of maize oil, olive oil, or palm oil for 9 weeks. Increasing saturation of dietary fa...

Deep-fat frying produces desirable or undesirable flavor compounds and changes the flavor stability and quality of the oil by hydrolysis, oxidation, and polymerization. Tocopherols, essential amino acids, and fatty acids in foods are degraded during deep-fat frying. The reactions in deep-fat frying depend on factors such as replenishment of fresh oil, frying conditions, original quality of fryi...

Useful medicinal and chemical properties of different parts of Eriobotrya Japonica seeds including flowers, fruits, and leaves have been investigated. In this study, fat content, moisture, unsaponifiable matter, saponification and iodine values, free fatty acid compound, individual sterols, antioxidant activity, total phenol, tannin, and flavonoids content, and detection and quantification of p...

The aim of this research was to assess the effect of fat type and concentration as well as the continuous phase viscosity on the rheological properties of an oil-in-water (O/W) emulsion. Thus, sunflower oil and tallow fat were used as the dispersed phase of the emulsion both at 10 and 50% (w/v) and CMC solutions (at 0.1, 0.3 and 0.5% w/v) were acted as the continuous phase. CMC solutions and em...

introduction: obesity and visceral fat accumulation after menopause are associated with insulin resistance and cardiovascular diseases. we investigated the interactive effect of aerobic-resistance training and estrogen replacement therapy on visceral fat, omentin-1 and homa-ir in ovariectomized rats. materials and methods: fifty female wistar rats were ovariectomized (ovx) and divided into 5 gr...

this experiment was conducted to evaluate the effect of emulsifiers such as lecithin and bile salts onbroilers performances fed diet containing vegetable fats. 192 male ross broiler chickens were randomlyallocated in a factorial experiment design of 3 × 2, consisting two sources of fat (four percent fatty acidsor soy bean oil) and three emulsifiers (none, one percent lecithin and 0.05 percent b...

The atherogenicity of corn oil, hydrogenated corn oil, and butter fat was studied using 57 fourty-day-old male Japanese quails. The animals were fed one of the following diets: basal diet, basal diet with corn oil plus cholesterol, basal diet with hydrogenated corn oil plus cholesterol, or basal diet with butter fat plus cholesterol. Each atherogenic diet contained 15% fat and 2% cholesterol. M...
