Abstract

The invention relates to a preparation method of a gold bean curd. The preparation method comprises the following steps: step S1, selecting beans, soaking and pulping, namely sorting high-quality soybeans; soaking in water with temperature of 20 to 50 DEG C for 10-15 hours; preparing soybean milk and boiling; step S2, curdling, namely adding edible vinegar of which the volume is 1-5 percent of the total volume of the soybean milk into the soybean milk until the milk is clear; and standing for 30 minutes; step S3, pressing and slicing, namely removing the clear liquid; pressing the bean curd; slicing the pressed bean curd into bean curd pieces; step S4, curing in a pot and drying, namely curing the bean curd pieces in alkaline water; drying the aged bean curd pieces until the water content is lower than 5%; step S5, soaking and drying in air, namely soaking the bean curd pieces in fresh water until the bean curd pieces fully absorb water; drying in air until the water in the bean curd pieces is uniformly distributed; step S6, performing microwave puffing, namely heating the bean curd pieces by microwave; fully absorbing water under a natural condition until the water content is 3-5 percent; and packaging to obtain a finished product. The preparation method disclosed by the invention is environment-friendly, healthy and free of any additives, and the prepared bean curd is attractive in appearance, good in taste, unique in flavor and huge in latent market value.

Description

technical field

[0001] The invention relates to the field of bean products, in particular to a method for preparing golden tofu. Background technique

[0002] Tofu is one of the main ingredients. Tofu is rich in a large number of nutrients, such as protein, fat, carbohydrates, fiber, iron, magnesium, potassium, niacin, copper, calcium, zinc, phosphorus, folic acid, vitamin B1, egg yolk In the existing tofu preparation method, bittern or gypsum is used to make bittern, and bittern mainly contains magnesium chloride, and gypsum mainly contains calcium sulfate. The above two compounds are harmful to human health to a certain extent. Calcium ions Magnesium and magnesium ions all have certain toxicity, which can cause protein coagulation in the human body, and is one of the main causes of gallstone diseases. It is not suitable for patients with gallstones. Therefore, there are many defects in the existing tofu preparation technology, which needs to be improved .
