Optimization of camellia oil film degumming process using response surface methodology
Taking camellia oil as the research object,Box-Behnken Response Surface Design was used to optimize the process conditions of camellia oil film degumming in order to explore the effects of membrane pore size,mixed oil concentration,and operating pressure on membrane degumming,and compare the effects of membrane degumming and hydration degumming processes on the quality of camellia oil.The results showed that the optimal process conditions for camellia oil film degumming were membrane pore size 10 ku,mixed oil mass fraction 35%,operating pressure 0.25 MPa,and the degumming rate after film degumming was 96.85%.Compared with hydration degumming,membrane degumming has significant effects on camellia oil degumming,decolorization,and deacidification,with a decolorization rate of 51.6%and the acid value decrease from 15.30 mg·g-1 to 0.64 mg·g-1.
