Abstract

The invention discloses a preparation method of a casing film. The raw materials in demand by the preparation method comprise: by weight, 50-60 parts of soybean protein, 1-8 parts of ultrafine microcrystalline cellulose. The preparation method comprises the following steps: S1100. a step of preparaing a soybean protein solution; S1200. a step of blending and modifying; S1300. a step of coating and drying. Further, the invention also discloses the casing film prepared by the method of the solution. The prepared edible casing film is high in tensile strength and good in product quality, and the elongation at break meets a sausage-filling requirement of meats.

Description

technical field [0001] The invention relates to a casing film, in particular to a casing film containing ultrafine microcrystalline cellulose and soybean protein and a preparation method thereof. Background technique [0002] Soybean is a traditional crop in my country, and its increasing yield provides abundant raw materials for the preparation of soybean protein. Soy protein contains a variety of nutrients, especially a large amount of amino acids, which provide the nutrients needed by the human body. Among them, isolated soybean protein and textured soybean protein have been widely used in meat products and dairy products. At present, the demand for casings in meat products is very large, but the natural casings of animals cannot meet the demand of the market. Some synthetic casings have problems such as low tensile strength, easy to break, inedible, and difficult to degrade. [0003] Therefore, the present inventor hopes to use soybean protein to replace animal protein...
