Abstract

The invention relates to the technical field of meat product fresh-keeping, and particularly relates to a composite biological fresh-keeping agent for meat and a preparation method of the composite biological fresh-keeping agent. The composite biological fresh-keeping agent for meat mainly comprises sodium alginate, lactobacillus helveticus fermentation liquor and lactobacillus casei fermentation liquor, wherein the lactobacillus helveticus fermentation liquor and the lactobacillus casei fermentation liquor are 55-65% and 35-45% of total amount of the fresh-keeping agent based on volume; and the sodium alginate is 3-5% of the total mass of the lactobacillus helveticus fermentation liquor and the lactobacillus casei fermentation liquor. The preparation process is as follows: uniformly mixing the lactobacillus helveticus fermentation liquor and the lactobacillus casei fermentation liquor which are 55-65% and 35-45% of the total amount of the fresh-keeping agent based on volume, adding the sodium alginate which is 3-5% of the total mass of the lactobacillus helveticus fermentation liquor and the lactobacillus casei fermentation liquor to be completely dissolved so as to obtain the composite biological fresh-keeping agent for the meat after uniformly mixing. The composite biological fresh-keeping agent for the meat has the advantages of simplicity in operation, convenience, low cost, safety, and no pollution, can prolong the storage time by 10 days in comparison with a common storage way, and can keep nutrition and flavor of chilled meat well.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping meat products, in particular to a composite biological fresh-keeping agent for meat and a preparation method thereof. Background technique [0002] Biological preservatives are safe and efficient preservatives, mainly including plant-derived ginger, garlic and tea polyphenols, animal-derived chitosan, lysozyme, etc., and microbial-derived nisin. [0003] Sodium alginate (sodium alginate), also known as sodium alginate; alginate, etc., is a natural polysaccharide compound extracted from kelp, fungi, and algae. A linear block copolymer formed by α-1,4 glycosidic bonds. It has many advantages such as excellent dispersibility, moisture retention, film-forming property, antibacterial property, non-toxic and tasteless, biodegradable, good biocompatibility, etc., and its cost is low. There are few reports on the application of meat products. Chen Lijiao and others published "Study on the Preserv...
