Stu~1ies on ,the mechanism of stereoselectivity of chromIUm tncarbonyl catalysts -with model com~ounds provided the basis for the preparation of sImulated fats. These synthetic fats were prepared by .taking advantage of the unique property of chromIUm carbonyl complexes to catalyze hydrogenation of polyunsaturates to cis-~onoui.I­ saturates. Oils simulating the composition of peanut oil were pr...

effect of methanolic leaf extract of moringa oleifera for the stabilization of butter oil with modified fatty acid profile at ambient temperature was investigated. twelve sahiwal cows of first and early lactation were randomly stratified into two groups in a completely randomized design and fatty acid profile of milk fat was modified by feeding 300 grams calcium salts of fatty acids (per cow pe...

The aim was to compare the effect on atherogenesis of dietary monounsaturated and saturated fatty acids in cholesterol-clamped rabbits. To obtain an average plasma cholesterol concentration of 20 mmol/l in each rabbit during the 13-week cholesterol-feeding period, dietary cholesterol was adjusted weekly. The amount of fat fed daily was 10 g per rabbit in Expts A (n 23), C (n 36), and D (n 58) a...

Replacement with the cheaper animal fats or vegetable oils is conventional in milk through direct incorporation or homogenization of skimmed milk with less expensive foreign fats. The main objective of the present study was to evaluate the capability of a simple, fast, and reliable method for the detection of added palm oil in butter. The butter samples were mixed with palm oil (0.5-50 wt%) fol...

The cholesteryl ester content of plasma low density lipoproteins (LDL) in monkeys has previously been shown to be related to the rate of hepatic cholesterol secretion and cholesteryl ester content of newly secreted lipoproteins in the isolated perfused liver. In the present studies, African green monkeys were fed diets containing cholesterol and 40% of calories as either butter or safflower oil...

Rabbits fed on semi-synthetic diets without added cholesterol develop hypercholesterolaemia and a form of atherosclerosis when butter (Wigand, 1959 ; Funch, Krogh & Dam, 1960) or hydrogenated fat (Wigand, 1959) is the sole dietary fat, whereas dietary vegetable oils or fat mixtures having high contents of polyenoic fatty acids increase the serum cholesterol levels only slightly and do not produ...

The high oil content of the avocado fruit (Persea americana Mill.) has been known since Aztec times, with the fruit sometimes referred to as “vegetable butter” or “butter pear.” The plant originated in Central America, and its cultivation has spread to warm subtropical and temperate climates worldwide. The flesh of an avocado can contain up to 30% oil (based on fresh weight), but there is very ...

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...
