Separation identification and targeted control method for specific putrefying bacteria of leisure dried bean curds

The invention relates to the technical field of preservation of dried bean curds, and discloses a method for separating, identifying and targeted control of specific putrefying bacteria in leisure dried bean curds, which comprises the following steps: S1, separating and identifying the specific putrefying bacteria in the leisure dried bean curds by utilizing a metagenomics technology; s2, screening a bacteriostatic agent with good bacteriostatic performance; and S3, optimizing the formula of the composite bacteriostatic agent. Specific putrefying bacteria in the leisure dried bean curds are separated and identified by utilizing a metagenomics technology, then the bacteriostatic agent with good bacteriostatic performance is screened, and then the natural bacteriostatic agent is optimized and compounded through a single factor experiment and an orthogonal experiment, so that the concentration and the type of the bacteriostatic agent with the optimal bacterial inhibition effect on the leisure ...
