Abstract
This study investigated the effectiveness of subcritical fluid extraction with dimethyl ether (SUBFDME) for extracting γ-oryzanol, phytosterol, and policosanols from rice bran oil byproducts. SUBFDME yielded high γ-oryzanol and phytosterol content compared to chemical extraction. Combining transesterification with SUBFDME significantly increased policosanol purity. SUBFDME is presented as a promising green technology for extracting and purifying these nutraceuticals.
