Method for preparing walnut oil by aqueous enzymatic method

The invention relates to the technical field of food, in particular to a method for preparing walnut oil by an aqueous enzymatic method, which comprises the following steps: under the condition of not adding water, crushing pretreated walnut kernels until the particle size of the crushed walnut kernels is less than or equal to 900 microns; adding water into the crushed walnut kernels to prepare walnut pulp; carrying out enzymolysis on the walnut pulp by using an aqueous enzymatic method; according to the method provided by the invention, the enzymolysis efficiency is greatly improved, and the final oil yield is up to 70% or above. 本发明涉及食品技术领域，具体涉及一种水酶法制备核桃油的方法，在不添加水的情况下，对预处理后的核桃仁进行破碎，破碎后的核桃仁的粒径≤900μm；在破碎后的核桃仁中加入水，配置成核桃浆；使用水酶法对核桃浆进行酶解；对酶解后的核桃浆进行分离，得到核桃油，通过本发明提供的方法极大的提高了酶解效率，最终的出油率高达70％以上。
