Problems solved by technology

In addition, meat processing companies often use pigskin with better integrity for processing low-temperature meat products, and use shredded pigskin during segmentation and processing as leftovers, especially shredded pigs with whiplash and bruises. The skin is often discarded, resulting in a very low utilization rate of pigskin, and the discarded pigskin pollutes the surrounding environment more seriously

Embodiment 1

[0029] Method of the present invention comprises the following steps:

[0030] (1) Selection of raw materials, trimming

[0031] Use clean, hygienic, non-infested areas, unbleached, and non-corrupted finely trimmed skins as raw materials, including whipped skins, bruised skins, and skins produced during the segmentation process; remove skin oil, pigs, etc. Hair and other impurities, subcutaneous fat content is controlled at 3%;

[0032] (2) Acid hydrolysis

[0033] Use a hydrochloric acid solution with a concentration of 36% for acidolysis, wherein the amount of hydrochloric acid added is according to the ratio of adding 5Kg water and 20ml hydrochloric acid to 1Kg broken skins for acidolysis, the acidolysis time is 3h, and the temperature of the water added in the whole process is room temperature;

[0034] (3) Boiling

[0035] Take out the pigskin that has been acidified, drain the water, add warm water to cook, the water temperature is controlled at 60°C, the amount of wa...

Abstract

The invention relates to a method for producing recombinant pigskin by using broken pigskin leftover materials, which comprises the following steps: (1) material selection; (2) acidolysis; (3) boiling; (4) filtering; (5) salination; (6) neutralization; (7) blending; (8) enzyme catalysis; (9) pouring and forming; and (10) air curing. The method uses broken pigskins including the broken pigskins produced through division processing, scourged pigskins, gore pigskins and the like as raw materials to produce the entire pigskin, and adopts a glutamine transaminage preparation to perform biocatalysis on the entire reaction system so as to achieve the recombination of the broken pigskins. Using the glutamine transaminage preparation to process the broken pigskins for recombination and forming, the recombinant pigskin cannot be re-dispersed due to freezing, slicing, stewing, cooking and the like. The method recombines the pigskins for reuse, which not only revalues the pigskins, but also reduces pollutions to the environment. The formed recombinant pigskin is convenient for processing and application, can substitute the prior pigskins in the process of low-temperature meat product processing, and greatly reduce the production cost.

Description

technical field [0001] The invention relates to a method for recombining shredded pigskin for industrialized production, in particular to a method for producing restructured pigskin by using scraps of shredded pigskin, which belongs to the field of food processing. Background technique [0002] In the past 20 years, my country's meat industry has developed rapidly, and the total annual meat output has exceeded 60 million tons, ranking first in the world. After years of reform and development, my country's meat industry has formed a complete industrial chain covering livestock and poultry breeding, slaughtering and segmentation, intensive processing, comprehensive utilization of by-products, cold chain transportation, logistics distribution, wholesale and retail, and related service industries. However, compared with the rapid development of meat and meat products, the comprehensive utilization rate of by-products such as skin, blood, bone, and viscera is not high, the degree...
