摘要
目的:探讨超声波辅助水酶法提取油莎豆油的最佳提取工艺条件。方法:以油莎豆油提取率为考察指标,采用单因素筛选出超声提取的最佳条件,以最佳超声条件结合水酶法提取油莎豆油,在对各影响因素进行单因素试验的基础上,通过正交试验确定最佳提取工艺并进行验证试验。结果:最佳水酶法提取工艺条件为:料液比1∶8,pH 9.0,酶解温度55℃,酶解时间3 h,酶用量2.5%,超声功率240W,超声时间7min,在此条件下提取率为(94.78±0.22)%。结论:该方法提取条件温和,操作简单可行,为油莎豆油的进一步开发利用提供科学依据。
Objective： The research aimed to study the optimum extraction technique of Cyperus esculentus L oil with uhrasonic-assisted aqueous enzymatic method. Methods：Taking the oil extraction efficiency as the observation index, based on Single factor to select the best ultrasonic extraction conditions,with this combination of ultrasonic aqueous enzymatic ex- traction of Cyperus esculentus L oil, on the influence factors on the basis single of factor experiment to determine the optimum extraction by orthogonal test and verify it. Results： The optimum extracting conditions by aqueous enzymatic were showed as following： ratio of stuff to water 1：8, do sage of Alealase 2.5 %, temperature 55 ℃, time3 h, pH 9.0. the ultrasound irradia- tion at 240W, time 7min ,the oil extraction efficiency is （94.78 ＋ 0.22 ）%. Conclusion：This method extraction conditions was mild, appropriate and feasible,it provided scientific basis for the future research of Cyperus esculentus L.
