Abstract: In order to improve the quality and reduce the loss of the nutritional content of camellia oil with the traditional press, this paper studied the process of pressing Camellia Oleifera Seeds with 10t/d Twin-Screw Oil Press. The results demonstrated that the best conditions for this article were: 9% moisture content of Camellia Oleifera seed kernels and 8% content of Camellia oleifera seed shell. The oil content of Camellia oleifera seed cake was reduced to 2.49%, and the produced camellia oil could meet the standard of first -class oil. In comparison to the camellia oil sold on the market, the retention rate of α-tocopherol in the camellia oil obtained through this process was higher, and the nutritional value of camellia oil has been further improved, which could provide technical guidance for the high-value processing of camellia oil in China.
Key words: Camellia Oleifera seed; twin-screw oil press; shelling and separation of shell and kernel; product quality
