The invention relates to a process for production of fatty acids directly from soapstock generated in the alkali refining process including the steps of (a) adding a lipase directly to the alkaline soapstock to facilitate hydrolysis of glycerides without prior neutralization, (b) neutralizing and splitting the soaps with strong acids, and (c) separating the fatty acid phase from the aqueous phase by settling and/or centrifugation. A second embodiment is a process in which the soapstock is first neutralized and split with strong acids, followed by adding a lipase to facilitate glyceride hydrolysis, and separating the fatty acid phase. The fatty acids so obtained can be esterified with C1-C6 alcohols using a lipase that is selective for fatty acids and does not transesterify the sterolesters, and the fatty acid esters and sterolesters are separated by distillation. The sterolesters are useful as supplements for food, as pharmaceutical agents for lowering cholesterol and as biofuel and biodiesel.

Process for production of fatty acids, fatty acid esters and sterolesters from soapstock

A process for the production of a color-stable composition containing cardanol, including (a) subjecting crude, cashew nutshell liquid to distillation to obtain a distillate; (b) reacting the distillate with acetic anhydride to obtain a reaction mixture; and (c) subjecting the reaction mixture to fractional distillation is provided. A method for the production of color-stable phenalkamines, including (a) subjecting crude, cashew nutshell liquid to distillation to obtain a distillate; (b) reacting the distillate with acetic anhydride to obtain a reaction mixture; (c) subjecting the reaction mixture to fractional distillation to obtain a cardanol-containing fractional distillate; and (d) reacting the fractional distillate with an aliphatic amine and formaldehyde to form a color-stable phenalkamine is also provided.
