Methods for concentration and extraction of lubricity compounds and biologically active fractions from naturally derived fats, oils and greases
First Claim
1. A process for extracting lubricity enhancing and biologically active compounds from oils, fats and greases, derived from animal and plant sources, comprising pressing a solid source material so as to release oils, fats and greases with lower levels of lubricity enhancing compounds, and solvent extracting pressed solid source material so as to produce a first oil, fat and grease concentrate of lubricity enhancing and biologically active compounds therefrom.

Abstract
Methods for recovery of concentrates of lubricating compounds and biologically active compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or biological activity or enrichment protocols that increase the concentration of high lubricity or biologically active compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds and biologically active compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can either contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction or the biologically active components may be used in nutritional, cosmetic and therapeutic applications. Therapeutic applications include use in human diets to lower cholesterol.
