Patent ID: 8784904

Claim:
A composition of matter comprising a shelf stable, supercritical, CO 2 fluid extracted seed oil derived from a cracked biomass of perilla frutescens , the seed oil comprising from 60 to 95 percent w/w of PUFAs in a ratio of from 4:1 to 6:1 alpha-linolenic acid (ALA) to linoleic acid (LA) and a mixture of selected antioxidants, wherein the perilla frutescens derived seed oil is made by subjecting the perilla frutescens seed to supercritical fluid CO2 extraction to produce a seed oil extract; fractionating the resulting seed oil extract in separate pressure step-down stages for collecting light and heavy fractions of seed oil extract; and separating the heavy fraction from the light fraction to form the final seed oil from the heavy fraction.
