Problems solved by technology

The preparation method of this type of casing is relatively complicated, and it is necessary to cross-link and modify soybean protein by adding glutaraldehyde to obtain good mechanical strength. The aldehyde chemical additives used, such as glutaraldehyde, are food processing aids. agent, which itself has a pungent odor and has a strong irritating effect on the eyes, skin and mucous membranes, and it is necessary to increase production safety protection measures during the processing; at the same time, the soy isoflavones and other substances contained in soy protein itself will make soy protein The product has a certain fishy smell, and additional processing is required when producing the product, otherwise it will have a certain impact on the flavor of the sausage product

Abstract

The invention discloses a collagen casing having a variety of application characteristics. The collagen casing is prepared by lamelliform and dispergated collagen fibers, a water-soluble collagen, vegetable fibers, a non-collagen type protein and glycerol. During preparation, the water content of the lamelliform and dispergated collagen fibers is adjusted to be 82 to 88% by means of water firstly, and then the lamelliform and dispergated collagen fibers are blended and kneaded with all other raw materials for 4 to 6 hours to obtain a collagen slurry material. After that, the water content of the collagen slurry material is adjusted to be 90 to 95% by means of water, and the pH value of the collagen slurry material is adjusted to be 2.5 to 3.0. Then, the collagen casing is shaped on a casing shaper and the pH value of the collagen casing is adjusted to be 4 to 6. After the drying and cooking process, a collagen casing finished product is finally obtained. According to the technical scheme of the invention, the collagen casing is good in mechanical strength during the casting and cooking process, and can be kinked and segmented at a high speed. During the cooking process, the collagen casing is free from being broken and is still good in chewiness. At the same time, a sausage prepared by the above casing is still kept in good shape and is prevented from being torn down, broken or decorticated during the water-boiling, frying and other high-temperature cooking process before eating.

Description

technical field [0001] The invention relates to a sausage casing packaging material for meat food, in particular to a collagen casing with various application characteristics and a preparation method thereof. Background technique [0002] Traditional casings were originally scraped from the large and small intestines of domestic animals and used to fill sausages and enemas. With the increase in market demand and technological development, artificial collagen casings have gradually replaced the main position of animal casings. , has become the main packaging raw material for sausage food at present. Collagen casing production technology has been greatly developed since its inception in the 1940s, and its products are also widely used in the sausage production industry in meat products. [0003] Looking at the existing collagen casing products circulating in the market, there is no obvious difference in the application characteristics of the products except for the great diff...
