FRACTIONATION OF PHYTOSTEROL ESTERS IN OIL

摘要

A composition comprising at least one diacylglycerol and at least one phytosterol and/or phytostanol ester dissolved or dispersed in an edible oil and/or edible fat, and further optionally comprising monoglycerides.Phytosterol esters may be beta-sitosterol, campesterol, stigmasterol and brassicasterol esters. Phytostanol esters may be stigmasterol, campestanol and sitostanol. The phytosterol and/or phytostanol esters are preferably esters of C14-C22, preferably C16-C18 saturated or unsaturated fatty acids, particularly oleic, linoleic, linolenic, palmitic and stearic acids. The diacylglycerol(s) are preferably 1,3-di-fatty acyl glycerol(s).The invention also provides a process for preparing compositions enriched with triacylglycerol(s) and phytosterol and/or phytostanol esters of mainly unsaturated fatty acid(s) or of mainly saturated fatty acid(s).The invention also relates to dietary food supplements and alimentary products comprising the composition of the invention.
