Background

The soybean milk is made of high-quality soybean, fully utilizes plant protein resources, uses plant protein, improves the protein value and the biological value, contains various vitamins and mineral substances, and has higher nutritional value. The soymilk beverage has fragrant and mellow mouthfeel, is smooth but not greasy, is beneficial to normal drinking, and is a healthy and nutritional soymilk beverage; the soymilk sold in the market has a plurality of varieties, proper price and convenient eating, thereby being popular with consumers.

However, in the preparation process of the soymilk, lipoxygenase in the beans degrades lipid substances to generate substances such as n-hexanol and the like, so that beany flavor is easy to generate, and the existing method and technology for improving and eliminating the beany flavor of the soymilk and bean products are mainly embodied in 3 aspects, namely, a new soybean variety lacking the lipoxygenase is discovered and cultivated through the improvement of raw materials; secondly, the beany flavor is reduced in the processing process, and the activity of the lipoxidase in the soybeans is passivated or inactivated; thirdly, at the later stage of processing, the formed beany flavor is eliminated or covered by additives; in addition, the soybean is easy to foam in the processing and manufacturing process of the soybean milk to influence the taste, so the skin of the soybean needs to be removed in the processing process of the soybean milk, but most of the existing soybean skin removing devices adopt a dry soybean friction peeling mode; the soybean peeling method has the disadvantages that the soybean is limited greatly and is damaged, and the soybean is difficult to clean because a great amount of bean substances and soybean hulls are adhered on the grinding wheel after peeling, so that the skin of the soybean needs to be removed by a new peeling method.
