Abstract:
1. A process for producing vegetable oil products containing one or more constituents from a group which includes monoacylglycerols, diacylglycerols, triacylglycerols, carotenes, tocols, phytosterols, squalene and free fatty acids, comprising: selectively extracting, without any pre-treatments of one or more source vegetable oils, and without using an adsorbent, from the one or more source vegetable oils, desired constituents and removing unwanted constituents and impurities by manipulating relative solubilities of the constituents and impurities in a supercritical fluid; and manipulating the relative solubilities of the constituents and impurities in the supercritical fluid by keeping a temperature, a flow rate of the supercritical fluid, and a composition of the supercritical fluid constant, and using a gradient pressure.
