Abstract:
A process comprisingmixing an optionally pretreated vegetable oil having a melting point of 32-55Â° C. with a solvent in a ratio of 1:3-7 (w/v), heating to transparency, and then cooling at a rate of 0.1-1.5Â° C./min to a first fractionation temperature of âˆ’5 to +10Â° C. to form one or more precipitated solid fractions suitable for use in confectionary applications, and filtering in one or more steps to separate a filtrate F1, optionally, mixing the filtrate F1 with an additional solvent; cooling the filtrate F1 at a rate of 0.1-1.0Â° C./min to a second fractionation temperature of âˆ’30 to âˆ’5Â° C. to form a second precipitated solid fraction, and filtering in one or more steps to separate a filtrate F2; distilling the filtrate F2 to remove the solvent and form a liquid fraction in which the unsaponifiable, biologically active components are enriched by at least a factor 2.
