Abstract
A composition of matter comprises a shelf stable, super critical, CO2 fluid extracted seed oil derived from a cracked biomass of perilla frutescens, the seed oil comprising from about 60 to about 95 percent w/w of PUFAs in a ratio of from about 4:1 to about 6:1 alpha-linolenic acid (ALA) to linoleic acid (LA) and a mixture of selected antioxidants.

A composition of matter comprising a shelf stable, supercritical, CO2 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.
A composition of matter comprising a shelf stable, supercritical, CO2 fluid extracted seed oil derived from a cracked biomass of perilla frutescens, the seed oil comprising from 85 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 the PUFAs are greater than 50 percent ALA, and a mixture of selected antioxidants, including astaxanthin, phenolic antioxidants and natural tocopherols, 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.
