摘要
为解决传统茶籽油精炼工艺中因加入脱酸碱炼剂、活性白土脱色剂而影响茶籽油品质的问题,通过将茶籽原油水洗后,利用无机陶瓷膜管与食品级活性炭耦合进行过滤,同时实现了脱胶、脱酸及脱色的目的,并对陶瓷膜管再生清洗进行了研究。结果表明,最优过滤条件为:陶瓷膜管孔径为100 KD、过滤温度70℃,过滤后,磷脂含量由1.542 mg/g降低至0.216 mg/g,脱胶率达到85.99%,酸价由5.56 mg KOH/g降低至1.4 mg KOH/g,脱酸率达到74.82%,色泽呈黄色,达到了茶籽油国家标准中一级油的相关指标要求。
In order to solve the problem that the quality of camellia oil is affected by the addition of deacidification 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 decolorization 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℃,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 KOH/g to 1.4 mg KOH/g,and the deacidification rate reached 74.82%,the color is yellow,meeting the requirements of the first grade oil in the national standard of tea seed oil.
