米糠储藏中的最大难题是其酸败速度极快。解决这一问题的最好办法就是使米糠中的脂肪酶钝化而失去分解脂肪的能力。使脂肪酶钝化的方法主要有以下几种。1．挤压法糙米加工成精米时，出机后的新鲜米糠立即通过螺旋挤压机产生摩擦热使脂肪酶钝化，同时还可杀死米糠中的微生物，从 The biggest problem with rice bran storage is its extremely high rancidity rate. The best way to solve this problem is to inactivate lipase in rice bran and lose the ability to break down fat. Lipase passivation methods are mainly the following. 1. When crushed brown rice is processed into polished rice, the fresh rice bran discharged from the machine immediately passes the frictional heat generated by the screw extruder to passivate the lipase, and at the same time, it can also kill the microorganisms in the rice bran from
