[0002] The fermentation principle of stinky mandarin fish mainly involves the action of microorganisms. In a high-salt environment, harmful bacteria are inhibited during the fermentation process, and the microbial community starts to decompose fish meat to produce a unique flavor. The main influencing factors of fermentation include temperature, salt concentration and fermentation time, which will affect the quality of fermentation and the flavor of the final product. In addition, the production process of stinky mandarin fish is complex, and the combination of traditional and modern processing methods makes the meat more mellow while maintaining the original flavor.
