Abstract

The invention provides a tender bean curd and a processing method thereof, and belongs to the technical field of bean product processing, and the processing method comprises the following steps: detoxifying soybeans, cleaning, crushing, soaking, grinding into soybean milk, centrifugally separating, adding calcium chloride into filtrate, standing, curing, and draining to obtain the tender bean curd. Anti-nutritional factors including a trypsin inhibitor, beany flavor components and the like in soybeans are removed by adopting a chemical steam method, meanwhile, a curing agent and a demulsifying agent calcium chloride are added into the emulsified soybean milk obtained after centrifugation, the demulsification and defoaming effects can be effectively achieved, the soybean milk can be rapidly cured to form the bean curd, and the bean curd quality is improved. The obtained bean curd is fine and smooth in taste, long in shelf life and widely loved.

Description

technical field [0001] The invention relates to the technical field of bean products processing, in particular to tender bean curd and a processing method thereof. Background technique [0002] Soybeans are widely planted all over the world. They are rich in sources and rich in protein, amino acids, vitamins and other essential nutrients. Foods made from soybeans are the best food for people with high blood pressure, diabetes and obesity. . Therefore, bean products are food commonly used in people's lives, and are deeply loved by consumers in general. At present, soybeans can be processed into a variety of convenient soy products. Among them, tofu is the most common soy product, which is rich in plant protein, a small amount of carbohydrates and fat, and is very popular among consumers. The main types are southern tofu, northern tofu and lactone tofu. The main production process of existing bean curd is: the one, pulping, be about to make soybean milk from soybean; [000...
