Embodiment 1

[0014] The sheep carcasses are produced in strict accordance with the hygienic requirements and slaughtering procedures, and the sheep carcasses are cleaned by spraying with a cleaning solution prepared in a weight ratio of lactic acid:ethanol:water=3:47:50, and matured in a constant temperature room at 4°C for 48 hours. hours, divided into 8 parts, soaked the divided mutton in the fermentation broth of Lactobacillus sake L.S-MA3-10 for 5 minutes, put it in a constant temperature room at 4°C for absorption, and vacuum-shrinked it when it felt obvious that there was no wet liquid. Then put it in a constant temperature library at 0°C for storage. Samples were taken on days 1, 3, 6, 9, 12, 15, 20, 30, and 35 to detect the total number of bacteria, coliforms, and volatile basic nitrogen. At the same time, the sensory indicators of the product were evaluated. Glossy, elastic tissue, with the inherent smell of fresh mutton, physical and chemical and microbiological indicators in lin...

Embodiment 2

[0016] The cattle carcasses are produced in strict accordance with the hygienic requirements and slaughtering procedures, and the cattle carcasses are cleaned by spraying with a cleaning solution prepared with a weight ratio of lactic acid: ethanol: water = 6:50:50, and the carcasses are matured in a constant temperature room at 4°C to deacidify 6 On the first day, the beef carcass was deboned and divided into 2-4 kg pieces according to the parts, and the fermentation liquid of Lactobacillus sake L.S-MA3-10 was sprayed on the surface of the meat at a rate of about 0.3 ml per square centimeter, and it was absorbed in a constant temperature room at 4°C. When it feels obvious that there is no wet liquid, vacuum shrink packaging is carried out, and then stored in a constant temperature warehouse at 0°C. Samples were taken on days 1, 3, 6, 9, 12, 15, 20, 30, and 35 to detect the total number of bacteria, coliforms, and volatile basic nitrogen. At the same time, the sensory indicator...

Abstract

The invention discloses a biological fresh-keeping method for cooled meat, which comprises the steps of surface cleaning, low-temperature deacidification, packaging and low-temperature fresh-keeping of freshly slaughtered livestock carcasses, and is characterized in that: the livestock carcass processed by low-temperature deacidification is used Lactobacillus sake L.S-MA3-10 (Lactobacillus sake) CGMCCNo.0690 was used for treatment. This method utilizes the action of dominant bacteria and the low pH value and produced bacteriocin to effectively inhibit the reproduction of spoilage microorganisms. A combination of various fresh-keeping technologies is used to strictly control the reproduction of spoilage microorganisms in each link of the production and storage process, which can prolong the product life. Longer shelf life, improved product hygiene and safety, in line with GMP, HACCP and other quality control management system requirements.

Description

technical field [0001] The invention relates to the field of meat processing and preservation, in particular to a biological preservation method for cooling meat. Background technique [0002] In order to achieve the best fresh-keeping effect and prolong the shelf life of chilled meat, various antiseptic preservatives are widely used in the prior art, and chemical preservatives mainly contain various organic acids and their salts. Such as acetic acid, formic acid, citric acid, lactic acid and its sodium salt, ascorbic acid, sorbic acid and its potassium salt, phosphate, etc. Natural preservatives are mainly plant extracts, such as tea polyphenols, allicin and alliin. Whether it is chemical preservatives or natural preservatives, excessive intake has a certain impact on human health. [0003] The present inventor isolated 675 strains of Lactobacillus sake on the basis of researching traditional fermented meat products (sour meat) of the Dong nationality, and screened out an...
