| 摘 要： | 以核桃仁为原料,采用水酶法提取核桃油脂,主要研究了预处理对核桃仁提油率的影响。结果表明,采用碱液去皮工序显著地降低了核桃清油提取率;适度地提高核桃仁的粉碎度,有利于核桃油的提取;浸泡工艺条件对核桃油的提取率有不同程度的影响;核桃仁粉碎浸泡后,采用酶钝化处理,可以显著提高油脂的提取率。

| Abstract: | The influence of pretreatment on percentage of walnut free oil extracted by aqueous enzymatic method was investigated.The results showed that lye(NaOH) peeling significantly reduced oil recovery rate.The increase of smashing degree was beneficial to walnut free oil extraction to some extent;Soaking conditions affected walnut oil extraction results.Enzyme deactivation could greatly enhance oil extraction rate after smashing and soaking. |
