【Abstract】 This optimal extraction parameters and the extraction rate of nutrient components of yellow flower camellia (C.Chrysantha(Hu) Tuyuma) were studied by enzymatic hydrolysis. With a ratio of 1∶100 between yellow flower camellia and water, an addition of 0.4% exogenous papain, pH 5.0～5.5, most of nutrient components and microelements were extracted at 50～55 ℃ for 2 hours. Under the above conditions, there were 39.47% increase of extraction rate of soluble solid, 7.39% increase of total soluble sugar and 1.84% increase of the extraction rate of crude protein amino acid by enzymatic hydrolysis, compared with by pure water extraction. The hydrolytic rate of crude protein was up to 25.5% and the extraction rate of Fe?Zn?Cu? Se?Mn?Co?Mo?Ge?V was up to 95% respectively in the optimal conditions.更多还原
