ABSTRACT:
Disclosed are processes for separating valuable products, including unsaponifiable materials, from any given matrix of raw materials that is mainly composed of saponifiable components and unsaponifiable components. Preferred methods include converting sodium or potassium soaps obtained from the saponification of a starting material into metallic soaps which have a lower melting point, and when melted, have viscosity sufficiently low to enable processing such as by distillation evaporation processes. Preferred raw materials include animal or vegetable products, as well as by-products, residues, and waste products from the processing of animal or vegetable products, such as from food processing, cellulose processing and the like. Valuable products which may be obtained by the disclosed processes include sterols, vitamins, flavonoids, and tocopherols.
