| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
