moisture level and particle size of soybeans, peanuts and cottonseed were correlated with the extraction rate and yield of oil when extracted with supercritical carbon dioxide (sc-co//2) at a constant temperature (50 c) and pressure (8,000 psig). the rate of extraction and ultimate oil yields were quite low with cracked soybeans. however, good extraction rates and nearly theoretical oil yields were obtained from ground or thinly flaked ( $less than$ 0 010') seeds. moisture levels between 3 to 12 had little effect on extractability. oil composition was not influenced by either parameter. scanning electron microscopy was used to study seed structure before and after extraction with sc-co//2. micrographs of sc-co//2-extracted seeds were similar to hexane-extracted seeds. 11 refs
