An aqueous enzymatic extraction method was used to extract oil from oil-tea camellia seed (Camellia oleifera). The factors influencing the yield rate such as enzyme kind, addition methods, concentration of enzyme, enzymatic hydrolysis time and temperature, and ration of solid to liquid were investigated. The results are as following: The acid protease and cellulase have higher oil yield rate than the other treatments, but there is no significant difference between acid protease and cellulase (Pw/w); the enzymolysis temperature and time, 55 ℃ and 3 h, respectively; and the ratio of solid to liquid, 1∶ 10.
