Abstract

The invention discloses a pretreatment method for freezing freshness keeping of pork. According to the method, the pork is put in pre-cooled partial freezing solution for partial freezing before freezing freshness keeping. By the partial freezing before the freezing freshness keeping, biological cell membranes of the pork are prevented from being damaged, and when the pork is de-frozen, no soluble proteins and cellular protoplasms are exosmotic, so that the nutritive materials are not lost, and the pork are kept fresh. In addition, by the partial freezing, lactic acids in the pork are converted into glycogens, so that the acid-removing process is eliminated when the pork is processed.

Description

technical field

[0001] The invention belongs to the field of meat food, in particular to a pretreatment method before freezing and keeping fresh pork. Background technique

[0002] Pork is the most important source of animal protein for the general public. According to statistics, more than 70% of the animal protein consumed in my country is pork and its products. The fluctuation of pork price is an important support point for leveraging CPI and is closely related to the lives of the people. . Our country has long formulated a mechanism to carry out strategic pork reserves when pork prices fluctuate, but in actual operation, various problems will be encountered. The biggest problem is that we dare not store too much pork in the national strategic reserve. Due to technical reasons, pork stored in cold storage for more than 3 months will deteriorate and cannot be eaten, so it must be processed in advance within 3 months , otherwise it can only be discarded completely, resulti...
