Problems solved by technology

Patent applications (201310607656.5) and (201911007241.8) mention that two mixed feed additives containing curcumin can improve pork quality to a certain extent, but both need to be mixed with other ingredients, and the role of curcumin is not clear
At the same time, the use of this type of additive in the production process has a long use time, high overall cost, and unstable effect, and there are certain limitations in technology promotion.

Embodiment 1

[0037] The processing of this embodiment is divided into three processing groups, specifically as follows:

[0038] (1) Take 30 pigs and divide them into three groups: control group, acetyltransferase inhibitor injection group, and deacetyltransferase inhibitor injection group 30 minutes before slaughter. The treatment methods are as follows:

[0039] ① Control group: The solvent was prepared at a volume ratio of 20% dimethyl sulfoxide and 80% normal saline, and the intraperitoneal injection dose was 0.97ml / kg body weight (control group C, n=10);

[0040]② Acetyltransferase inhibitor injection group: take curcumin, dissolve it in dimethyl sulfoxide, make curcumin mother solution with a concentration of 80 mg / mL, and inject curcumin mother solution intraperitoneally at a dose of 20 mg / kg body weight, with a total amount of 30 mL (Ati ,n=10);

[0041] ③Deacetyltransferase inhibitor injection group: Trichostatin A injection was dissolved in dimethyl sulfoxide to prepare trichost...

Abstract

The invention discloses a method for improving pig stress and meat quality by using protein acetylation inhibitors. The method comprises: intraperitoneal injection of curcumin half an hour to 1 hour before slaughter, with a dose of 15‑20 mg / kg, which can significantly reduce The stress level of pigs, manifested by decreased concentrations of creatine kinase, lactate dehydrogenase, cortisol, and heat shock proteins in the blood; The quality of meat products has been significantly improved, manifested by decreased activities of creatine kinase and hexokinase, increased activity of pyruvate kinase, high glycogen and ATP content, low lactic acid content, slowed decrease in muscle pH, and decreased incidence of PSE meat. This method not only reduces animal stress, but also improves meat quality.

Description

technical field [0001] The invention relates to a method for improving pig stress and meat quality by using protein acetylation inhibitors, and belongs to the technical field of food processing. Background technique [0002] In my country, pork is one of the indispensable animal source foods for most people, and it is an important source for people to obtain high-quality protein, heme iron, zinc, and B vitamins. In recent years, as people's requirements for a better life have become higher and higher, there are many high-quality pork products among them. [0003] In the process of industrialized pig slaughtering and processing, due to the influence of factors such as long-distance transportation, high-temperature and high-humidity climate, low temperature and cold temperature, and improper driving by humans, animals are seriously stressed before slaughtering, and PSE meat (Pale Soft Exudative Meat, white muscle) etc. The incidence of pork with poor appearance and eating qua...
