Abstract

The invention discloses a treatment method for conveniently removing rabbit skin and flesh, which belongs to the technical field of rabbit skin tanning, and comprises the following steps: S1. soaking rabbit skin at normal temperature, completely soaking and softening until the skin returns to a fresh skin state; S2 .At normal temperature, put the rabbit skin soaked in S1 into the sore swelling solution for 3-8h; S4. Put the rabbit skin treated by S3 into water at 30-35°C, and then add lipase to the water; S5. Put the rabbit skin treated by S4 into the second detumescence solution and soak overnight at normal temperature. The treatment of the present invention facilitates the removal of the skin and flesh of the rabbit, and there is no obvious loss of the strength of the skin plate, which reduces the cumbersome operation of the purely mechanical method or manual method, is convenient to operate, and is more suitable for industrialization needs.

Description

technical field [0001] The invention belongs to the technical field of rabbit skin tanning, and in particular relates to a treatment method for conveniently removing rabbit skin and flesh. Background technique [0002] Tanning is a process in which tanning agent molecules penetrate into the skin and combine with active groups of raw hide collagen molecules to change their properties. Tanning can generate cross-links between the collagen polypeptide chains of the skin, increase the stability of the collagen structure, increase the shrinkage temperature and the stability of moisture and heat resistance, and improve the ability to resist acids, alkalis, enzymes and other chemicals. Raw hides must go through a series of preparatory processes such as soaking in water, dehairing, liming, softening, pickling, etc. before tanning in tanning. The above processes leave raw hides mainly with a fiber network composed of collagen, but they are not leather or raw hides. Tanning is genera...
