摘　　要：为了获得富含生物活性成分的高品质油茶籽油,采用湿法提取油茶籽仁中油脂,并采用响应面实验优化工艺条件。结果表明:最佳工艺条件为加水量12%、提油助剂添加量1%、提取温度55℃、提取时间50 min;在最佳工艺条件下,油茶籽仁的提油效率达86%以上,所得油脂基本不含固杂,其中的生物活性成分维生素E、角鲨烯和谷甾醇含量分别高达189.0、221.9 mg/kg和385.2 mg/kg,高于T/LYCY 001—2020《特、优级油茶籽油》中优级油茶籽油的相应指标值,为高品质油茶籽油产品的开发提供了新思路。In order to obtain high quality oil-tea camellia seed oil rich in bioactive components,wet extraction method was used to extract oil from oil-tea camellia seed kernel,and the extraction conditions were optimized by response surface methodology.The results showed that the optimal extraction conditions were obtained as follows:water dosage 12%,dosage of oil extraction assistant 1%,extraction temperature 55℃and extraction time 50 min.Under the optimal conditions,the oil extraction efficiency of oil-tea camellia seed kernel was above 86%,and the oil basically contained no solid impurities,and the contents of vitamin E,squalene and sitosterol were as high as 189.0,221.9,385.2 mg/kg,respectively,which were higher than the corresponding index values of standard Extra oil-tea camellia seed oil(T/LYCY 001-2020).It provides a new idea for the development of high quality oil-tea camellia seed oil products.
