摘要
以茂名产黄橄榄为原料,采用超声波法辅助萃取橄榄浸膏,考察了温度、时间、超声波功率对萃取效果的影响,并在单因素的基础上采用三因素四水平正交实验优化了萃取工艺条件。结果表明,当温度为60℃,时间为40min,超声波功率为210 W时,萃取工艺条件最佳,橄榄浸膏萃取率可达7.225%。
The ultrasonic assisted extraction technology for the olive extract,which takes starch of Maoming yellow olive powder as material and extraction yield as evaluation indexes,is investigated.And the effects of ultrasonic power,extraction temperature and time on the extraction are studied.On the basis of single factor,the optimal extraction condition is discussed by the three factors four levels orthogonal.The results show the optimum technological conditions：extraction temperature is 60℃;extraction time is 40min;extraction power is 210 W.Under this condition,the extraction rate of olive extract gets up to 7.225%.
