Preparation method of edible animal collagen casing

Abstract

The invention discloses a preparation method of an edible animal collagen casing. The preparation method comprises the following steps: a, material preparation: cleaning and splitting animal skin; b,material treatment: performing alkali treatment on the split animal skin, adding water according to a weight ratio of the animal skin to the water of 1:1, performing enzyme treatment with protease, cleaning the animal skin, and then, performing acid treatment; c, preparation of fiber pulp: cooling the animal skin after acid treatment to be lower than 10 DEG C, cutting up the animal skin by means of dicing, tabletting, chopping and grinding or a combination mode thereof, rolling the cut animal skin into sheets, and extracting silk fiber by means of high pressure filtration; d, preparation of collagen pulp: adding edible cellulose or edible cellulose derivates and grease emulsion while stirring, controlling pH value and water content, and performing uniform mixing and stirring to form a collagen group; e, preparation of casing: freezing the collagen group, performing extrusion to spray a tubular substance, drying the tubular substance, and adding a curing agent and a plasticizing agent for treatment; f: curing and forming: curing and shaping the casing for 6 hours at 82 DEG C; and g: defect detection: detecting whether the casing is broken or not by using a casing detection device.

Description

technical field [0001] The invention belongs to the field of preparation methods of edible animal collagen casings, in particular to a preparation method of edible animal collagen casings. Background technique [0002] Edible animal collagen casings have been commercialized in foreign countries and have been widely used in meat processing for decades. The performance of the casing, the production methods of edible animal collagen casing can be divided into two types: dry production method and wet production method, but the existing edible animal collagen casing preparation method requires manual inspection after the preparation is completed. loopholes, resulting in lower work efficiency and higher labor costs. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the present invention provides a method for preparing an edible animal collagen casing which can automatically detect whether there are loopholes and thus does not require manu...

Problems solved by technology

[0002] Edible animal collagen casings have been commercially produced abroad and have been widely used in meat processing for decades. According to the degree of degradation of collagen fibers in animal hides, the degree of homogenization, the moisture content of collagen before molding, the post-molding process and Casing performance, the production methods of edible animal collagen casings can be divided into dry production method and wet production method, but the existing preparation methods of edible animal collagen casings need manual inspection after the preparation Vulnerabilities, resulting in lower work efficiency and higher labor costs
