Abstract
Supercritical fluid fractionation (SFF) technology has been applied as an alternative method to recover phytosterol (St)-enriched triglyceride (TG) fractions from vegetable oil deodorizer distillates (DD). Utilizing a pilot scale high pressure packed column, it was possible to obtain oil fractions with 20 and 31% St, 38 and 30% TG, from rice bran and soybean oil DD, respectively. A two step SFF method was developed further to obtain low free fatty acid and high TG and St content oil fractions from rice bran and soybean oil DD.Keywords
