Salting process of freshwater fish

The invention discloses a salting process of freshwater fish. The salting process comprises the following steps of killing, washing, salting, drying and packaging. In the salting step, the whole treated fish is placed into salting liquid and salted for 24-36 hours at 10-15 DEG C. The proportions of the prepared salting liquid are as follows: 1000 liters of salt solution with the concentration of 4%, 20-30 liters of glucose solution with the concentration of 50%, 10-12 liters of zinc gluconate solution with the concentration of 10% and 10-20 liters of mixed fermenting agent with the concentration of 10%; and the mixed fermenting agent is the mixed fermenting agent with the concentration of 10%, which is prepared by adding water into lactobacillus casei and lactobacillus plantarum in a mass ratio of 1: 1. According to the salting process of the freshwater fish, probiotics and zinc ions are added into the salting solution with low baume degree, a substrate concentration activating enzyme is increased, the probio
