Problems solved by technology

[0007] In the current process of using split leather to produce pet glue, due to the irregular shape of natural animal skin and the poor quality of the corners of the split leather, a large amount of trimmings will be generated when preparing pet glue , due to the relatively small area of ​​this kind of residual material, it is impossible to produce higher-grade pet glue products through operations such as knotting, so the added value is very low, resulting in the problem of relatively low utilization of natural resources
[0008] In addition, the trimming operation after the tanning production of the middle gray leather will produce a large number of leather pieces with relatively small area and uneven thickness. The composition and structure of this kind of leather pieces are consistent with the two-layer gray leather currently used for the production of pet glue. , the price is lower than that of split leather, but due to the limitation of size and thickness, it cannot be used to produce pet glue products, so that limited natural resources cannot be fully utilized

Abstract

The invention discloses a collagen pet glue. Its components are collagen fibers, collagen and auxiliary components. The collagen fibers and collagen are extracted from animal skins. Collagen is wrapped on the collagen fibers. The auxiliary components include cross-linking materials, meat and / or Materials with food-attracting and nutritional functions. The invention also discloses a preparation method of the collagen pet glue.

Description

technical field [0001] The invention relates to the field of animal product processing, in particular to a collagen pet glue and a preparation method thereof. Background technique [0002] Collagen fiber, the main component of animal skin, is a kind of protein. In addition to good mechanical properties and formability, it is also edible, so it can be used as pet glue and is widely used in making pet chewing products. The animal skins used to produce pet rubber are generally the second or third layers of leather left after tanning. Since the second or third layers of leather do not have the natural grain of the top layer of leather, the added value of tanning is relatively low, so It can be used in the production of pet glue products. [0003] Although the collagen fibers in animal skins are proteins and are edible, the structure of the skins is firm and hard, making it difficult for pets to chew them, and the collagen fibers are hard proteins, which are not easily digested ...
