摘要
以油莎豆为原料,采用水酶法建立一种油莎豆油提取新工艺。通过单因素和正交试验,对水酶法提取油莎豆油的工艺进行了优化。结果表明,最佳提油工艺为:料液比1∶7,加酶量0.4%,酶解温度40℃,酶解时间10 h。在此条件下提油率高达86.82%。在上述影响因素中,混合酶的添加量为主要影响因素,其次是酶解温度,再次是料液比,酶解时间影响最小。
A new technology of preparing Cyperus esculentus oil was developed using aqueous enzymatic method. Through single factor experiment and orthogonal test, the optimal process parameters were optimized as follows : ratio of material to solvent 1 : 7, dosage of enzyme 0.4% , temperature of enzymatic hydrolysis 40 ~C and time 10 h. Under these conditions, the oil extraction rate was 86.82%. The significance of the effects of these factors on oil yield was in the order: dosage of enzyme 〉 temperature of enzymatic hydrolysis 〉 ratio of material to solvent 〉 extraction time.
