Production method of bean dreg protein powder

Abstract

The invention discloses a production method of bean dreg protein powder, and the production method comprises the following steps: (1) pretreating raw materials; (2) carrying out differential pressuretype vacuum puffing to modify and treat bean dreg; (3) carrying out enzymolysis; (4) performing enzyme deactivation and centrifugation; (5) performing high-temperature closed cooking treatment; (6) performing high-pressure homogenization; (7) performing spray drying; and (8) performing sterilization treatment. The bean dreg is taken as a main raw material to be subjected to combined treatment of high-temperature closed cooking and differential pressure type vacuum puffing to prepare a novel modified treated bean dreg raw material, and a high-temperature closed cooking and differential pressuretype vacuum puffing treated novel bean dreg dietary fiber- protein reinforced powder product is prepared by combination of site-controlled enzymolysis, high-pressure homogenization and high-temperature instant sterilization technologies, the bean dreg protein powder product has the health-care functions of good water solubility, water retention, expansibility, blood sugar reduction and the like,the product is high in stability, simple in process and low in production cost, the high-value utilization process of byproducts of soybean products is promoted, and a certain reference and a basis are provided for the development of bean dreg dietary fiber functional products.

Description

technical field [0001] The invention belongs to the field of protein powder production, and mainly relates to a production method of high-temperature airtight cooking combined with differential pressure vacuum puffed bean dregs dietary fiber-protein fortified powder. Background technique [0002] China is a major producer and consumer in the world, and the amount of soy products processed is huge, resulting in a large amount of by-product bean dregs. Calculated by processing 1 ton of soybeans, 2.5 tons of bean dregs can be produced. Today, about 10 million tons of bean dregs are produced in China every year. However, due to the large particles of bean dregs, rough taste, high water content, and easy to rot and not durable, a small part is eaten and mostly used as food or directly discarded, resulting in a huge waste of resources. However, soybean dregs are rich in nutrients such as protein, fat, minerals and dietary fiber. The dietary fiber contained in it has physiologica...
