Abstract

The invention discloses a treatment method convenient for removing meat on rabbit skin, and belongs to the technical field of rabbit skin tanning. The treatment method comprises the following steps: S1, soaking rabbit skin at the room temperature, and completely soaking and softening until the skin returns to a fresh skin state; S2, at the room temperature, putting the rabbit skin subjected to a soaking treatment in the step S1 into an acid swelling solution, and soaking for 3 to 8 hours; S3, at the room temperature, putting the rabbit skin subjected to acid swelling soaking in the S2 into a first de-swelling solution, and soaking for 16-20 hours; S4, at a temperature of 30-35 DEG C, putting the rabbit skin treated in the S3 into water, and adding lipase into water; and S5, at the room temperature, putting the rabbit skin treated in the step S4 into a second de-swelling solution, and soaking for one night. According to the method, the meat on rabbit skin can be conveniently removed, the skin plate strength is not obviously lost, the tedious operation of a pure mechanical method or a manual method is reduced, the operation is convenient, and the method is more suitable for industrial production.

Description

Technical field [0001] The invention belongs to the technical field of rabbit skin tanning, and specifically relates to a processing method that is convenient for removing rabbit skin meat. Background technique [0002] Tanning is a process in which the tanning agent molecules penetrate into the skin and combine with the active groups of the collagen molecules to change the properties. Tanning creates cross-linked bonds between the skin collagen polypeptide chains, increases the stability of the collagen structure, improves the shrinkage temperature and humidity resistance stability, and improves the ability to resist acids, alkalis, enzymes and other chemicals. Before tanning, raw hides must undergo a series of preparatory processes such as water soaking, dehairing, liming, softening, and pickling. The above-mentioned processes leave the raw hides mainly with a fibrous network composed of collagen, but it is not leather but raw hides. Tanning is generally carried out in a rotat...
