Abstract

The invention belongs to the technical field of food processing, and discloses a preservative and fresh-keeping method for prefabricated meat dishes. The method comprises the following steps: slowly dropwise adding a probiotic liquid into a sweet tea polysaccharide extract under the condition of continuous stirring, uniformly mixing, slowly adding a chitosan solution, and stirring to react for 1-3 hours to obtain the sweet tea polysaccharide extract and chitosan-embedded probiotics; uniformly covering the surface of the prefabricated meat dish with the sweet tea polysaccharide extract and the chitosan-embedded probiotics, cooling at 0-4 DEG C for 30-40 minutes, and freezing and preserving. According to the preparation method disclosed by the invention, the probiotics are embedded by utilizing the sweet tea polysaccharide extract and the chitosan, a product obtained by embedding directly covers the surface of the prefabricated meat dish, and the sweet tea polysaccharide extract not only can be used as a material for embedding the probiotics, but also has antibacterial and antioxidant effects; the product can play a synergistic antibacterial and antioxidant role with probiotics, so that the shelf life of the prefabricated meat dish is remarkably prolonged, and the flavor of the product is improved.
