There are many researches on oil extraction, of which the conventional methods include mechanical pressing and organic solvent lixiviation process. In this research, the tea-seed, which is a kind of traditional oilseed from woody plants, was chosen as the raw material to explore a new extracting method and conditions of supercritical CO2extraction, aqueous extraction and aqueous enzymatic extraction were optimized. The quality and fatty acids composition of camellia oil extracted by different methods were s...
