Problems solved by technology

[0003] Purpose of the invention: In view of the existing restructured pigskin technology, hydrochloric acid solution is often used for soaking, and hydrochloric acid solution is a dangerous chemical product, which is difficult for small and medium-sized enterprises to purchase. Some technologies use citric acid instead of hydrochloric acid for soaking, but the effect of simply using citric acid to increase hair is poor. After the pigskin is not thoroughly glued, the hardness of the restructured pigskin is poor, and the reconstituted pigskin after soaking in sodium hydroxide solution is dark in color and poor in toughness

Abstract

The invention discloses a production method of recombined pigskin for a foot bundle. The production method comprises the steps of taking the pigskin in a non-epidemic area as a raw material; cleaning the pigskin to remove foreign matter and subcutaneous fat; cooking the cleaned pigskin with boiled water for sizing; cutting the sized pigskin into dices, and separately carrying out organic acid soaking, clean water soaking and draining technologies on the pigskin; then utilizing a compound protease liquid for enzymolysis of the pigskin, and conducting high-temperature enzyme deactivation; sufficiently and uniformly mixing a pigskin enzymolysis liquid, glutamine transaminase and compound glue, then pouring a mixture into a mold for forming, and finally conducting demolding to use the recombined pigskin. The combined pigskin produced by means of the method has a regular shape and high elasticity and toughness, and can be used for production of the foot bundle.

Description

technical field [0001] The invention belongs to the technical field of deep processing of meat products, and relates to a production method of recombined pigskin. Background technique [0002] The number of live pigs raised in my country ranks first in the world. According to statistics, the number of live pigs in my country in 2015 was 451.125 million. As a by-product of pig slaughtering, pigskin is cheap (about 3 to 4 yuan per catty). Most of the pigskin is water, the water content is 70-75%, the protein content is 21-23%, the fat content is about 1%, and the ash content is about 0.5%. The protein in pigskin is mainly collagen, with a content of about 87%. The protein content in pigskin is 2.5 times that of pork, the content of carbohydrates is 4 times higher than that of ordinary pork, and the fat content is very low but only half of pork. Pigskin is composed of thin epidermis, firm dermis, and soft subcutaneous connective tissue, the main component of which is the derm...
