Problems solved by technology

[0006] Among the many enzyme and odor removal methods, microwave blanching heats the sample directly from the inside to the surface. The microwave penetrating power is stronger, and the enzyme is more thorough and uniform, but the energy consumption is large, and at a lower power, the enzyme inactivation time is longer. long

Abstract

The invention discloses a technology of soybean peeling and enzyme killing with a microwave method. The technology includes the steps of 1), pretreatment, namely performing cleaning, stone removing and selection of soybean raw materials; 2), vacuum microwave cracking; 3), peeling, namely performing winnowing peeling to obtain peeled soybeans; 4), soaking; 5), draining; 6), enzyme skilling by steam; 7), enzyme killing by microwave; 8) cooling; 9), after-treatment, and performing vacuum package on the soybeans obtained in the step 8) can cooling the soybeans to room temperature. The technology for soybean enzyme killing by vacuum microwave soybean peeling and steam microwave is provided, microwave penetration is strong, the material is heated from inside and outside simultaneously, heating efficiency is quite high, the soybeans can be peeled rapidly, and meanwhile, the activity of harmful enzymes in the soybeans can be reduced by microwave; under vacuum, the temperature of soybean peeling and enzyme killing is decreased, and protein denaturation is decreased; meanwhile, due to reduction of oxygen concentration in vacuum, the degree of oxidation of oil is also significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a process for soybean peeling and enzyme inactivation by microwave method. Background technique [0002] Soybean contains 40% protein, 20% fat, and 30% carbohydrate. Among grains and other legumes, soybean has the highest protein content and the second fat content. With its unique chemical composition, soybean has become the most economically valuable And one of the agricultural products with use value. [0003] In order to produce high-quality soybean products, dehulling has become an indispensable process for soybean pretreatment. Commonly used soybean peeling methods include hot peeling and cold peeling. The peeling effect of the cold process is poor, and it needs to be heated twice, the heating time is long, the energy consumption is large, and the production cycle is too long. The thermal peeling process also has the problems of high en...
