Embodiment 1

[0061] A kind of tofu processing method of the present embodiment comprises the steps of material selection, soaking, pulverizing, separating, pulp filtering and boiling pulp, and the specific operation process is as follows:

[0062] (1) Material selection: choose soybeans with full grains, no insect erosion, and no impurities.

[0063] (2) Soaking: Wash the soybeans and place them in soaking water for soaking treatment. The pH value of the soaking water used in this example is 6.8, the mass ratio of soybeans to soaking water is 1:2.4, and the soaking time is 6 hours.

[0064] (3) Pulverization: clean the soaked soybeans, place them in a refiner and add water for grinding. The mass ratio of soybeans controlled by the present invention is 6.5:1, the grinding time is 3s, and the grinding precision is 100-150 mesh.

[0065] (4) Separation and slurry filtration: the ground soybean milk is added into a centrifuge for three separations, and the obtained soybean milk after each sepa...

Abstract

The invention discloses a processing method of bean curd, tender bean curd and refreshment made from bean milk and belongs to the technical field of processing of soya bean products. The processing method comprises the steps of material selection, soaking, smashing, separation, milk filtration and milk boiling, wherein the milk boiling temperature is 30-105 DEG C, the milk boiling time is 12-16 minutes, and a defoaming agent is added in the milk boiling process and is prepared by compounding organic silicone oil, modified soyabean lecithin, soybean oil and water. The defoaming effect in the bean curd processing process can be effectively improved by optimizing compounding of the components of the defoaming agent and optimizing the design of a bean curd processing technology, the usage amount of the defoaming agent is small, and the limited requirement for the use amount of polydimethylsiloxane in the national standard can be met.

Description

technical field [0001] The invention belongs to the technical field of bean products processing, and more specifically relates to a processing method of tofu, soft tofu and firm tofu. 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 f...
