saturated fat consumption increases the risk of both coronary and cancer diseases. therefore, fat reduction in uf-feta cheese (≈ 45% fdm) is favorable but, unfortunately, it has some negative effects on the texture and sensory characteristics of the cheese. in this research, response surface methodology was employed to study the probably improving effects of wpc80 (0-20 gr kg-1), lecithin (0-2 ...

Xerosis is a common skin condition as well key aspect of number diseases associated to hereditary and acquired conditions. The objective this study was formulate evaluate the pluronic lecithin organogel containing natural moisturizing agents for topical application. Different formulations organogels were prepared by using Pluronic F127, Lecithin, Vitamin E, Aloe vera, water, sorbic acid, potass...

The purpose of the present study was to assess the role of the liver in the plasma-cholesterol-lowering effect of soyabean lecithin. Normolipidaemic rats were fed on lecithin-enriched or control diets with the same amount of protein. The lecithin diets contained 200 g/kg high-fat commercial semi-purified soyabean lecithin (230 g/kg total lipids as soyabean phosphatidylcholine) or 200 g/kg high-...

A practical and easily reproducible method for preparing lecithin of a high degree of purity is urgently needed in connection with the use of lecithin in cardiolipin antigens (1, 2). Methods devised for this purpose have been published (3, 4), but the procedures, based on the classic studies of Levene and his coworkers (5, 6), were somewhat tedious and the lecithins so prepared have not always ...

In vitro studies were performed to investigate a possible mechanism by which lecithin suppresses intestinal cholesterol absorption. The hypothesis that lecithin acts by retarding the diffusion of micelles across the unstirred water layer (UWL) was tested by measuring cholesterol influxes (Ji) in segments of rat intestine under conditions with no maximal and minimal effective thickness of the UW...

Hanahan and Jayko (1952) isolated a pure individual unsaturated lecithin, L-ox-(dipalmitoleyI)lecithin, from fresh baker's yeast by adsorption on alumina. They showed that hydrogenation of this material produced the corresponding saturated lecithin which was identical with the synthetic L-oc-(dipalmitoyl)-lecithin of Baer and Maurukas (1952). The latter compound, when used in combination with c...

The interactions of proteins during the heat treatment of whey-protein-isolate (WPI)-based oil-in-water emulsions with and without added hydroxylated lecithin were studied by examining the changes in droplet size distribution and the quantity and type of adsorbed and unadsorbed proteins. Heat treatment at 90 degrees C of WPI emulsions resulted in an increase in total adsorbed protein; unadsorbe...

The present studies were undertaken to determine the extent to which the phospholipid composition of Neurosporn crama can be altered by mutations studied in conjunction with controlled supplementation. Previous work in this laboratory has shown that a mutation involving an enzyme concerned with lecithin synthesis can result in a lecithin-deficient strain (1, 2). The methylation of phosphatidyle...
