摘要
分别采用超声波、碱皂化和脂肪酶对海参卵进行预处理,研究了预处理工艺对类胡萝卜素提取率的影响。结果表明,采用脂肪酶对海参卵进行预处理后再行提取,有效成分的提取率大幅度增加,类胡萝卜素提取率提高了49.4%。预处理工艺条件为:脂肪酶用量100 U/g,35℃条件下反应35 min。提取率为81.7%。
Methods of ultrasonication,alkali,and lipase were used to pretreat sea cucumber ovum,and their effects on extraction rate of carotenoids were studied.The result showed that the extraction rate of effective components increased greatly after pretreatment with lipase,and the extraction rate of carotenoids increased by 49.4%.The optimal process was the sea cucumber ovum was treated before extraction with 100U/g of lipase in 35 ℃for 35 min,and the extraction rate could reach to 81.7%.
