Experimental study on refining camellia oil with inorganic Ceramic membrane.

In order to solve the problem that the quality of camellia oil is affected by the addition of DE acidification and alkali refining agent and active clay bleaching agent in the traditional tea seed oil refining process, after the tea seed crude oil is washed, the inorganic ceramic membrane tube and food grade activated carbon are used for coupling filtration. At the same time, the purpose of degumming, deacidification and decolonization is realized, and the regeneration cleaning of ceramic membrane tube is studied. The results show that the optimum filtration conditions are: the pore diameter of ceramic membrane tube is 100 KD, and the filtration temperature is 70 C, after filtration, the phospholipid content decreased from 1.542 mg/g to 0. 216 mg/g, and the degumming rate reached 85. 99%, the acid value decreased from 5.56 mg IKOH/g to 1.4 mg IKOH/g, and the DE acidification rate reached 74. 82%, the color is yew, meeting the requirements of the first grade oil in the national standard of tea seed oil.
