Technical Field

The invention relates to the technical field of food processing, in particular to a high-protein dried bean curd stick formula and a production process thereof.

Background

The dried beancurd stick is also called beancurd sheet, is a traditional Chinese bean food, is a common food raw material in China, has strong bean fragrance, and has unique mouthfeel which is not possessed by other bean products. The dried beancurd sticks are yellow and white in color, glossy and transparent, rich in protein and various nutritional ingredients, and can be developed after being soaked in clear water (cool in summer and warm in winter) for 3-5 hours. Can be used for meat, vegetable, cooking, frying, cold mixing, soup and the like, has faint scent and good taste, and has unique flavor for meat and vegetable. However, patients with nephritis, renal insufficiency, diabetic ketoacidosis and gout are not suitable for eating dried beancurd sticks.

The dried bean milk is boiled, and after a period of heat preservation, a layer of film is formed on the surface, and after being picked out, the film sags into branch strips, and then the dried bean milk is obtained. It is similar to the branch of a bamboo, and is called a dried bean. The dried bean curd stick is a product with a certain structure and composed of a soybean protein film and fat. High nutritive value, easy preservation and convenient eating, and is deeply favored by consumers at home and abroad.

Although the existing dried beancurd sticks contain more protein, the existing dried beancurd sticks still do not meet the standard of high-protein food, and other food is required to be matched to meet the requirement of human body on protein in daily life, so that more food needs to be cooked, one person can easily waste the food, and a large amount of cooking time is consumed.
