Description

Pickled Chinese cabbage fish processing technology
Technical Field
The invention relates to the technical field of food processing, in particular to a pickled Chinese cabbage fish processing technology.
Background
The pickled Chinese cabbage fish as a classic Sichuan fish dish is popular in China because fish meat is fresh, fragrant, tender and smooth, soup is sour and hot, and appetite is promoted by people in pursuit, but the preparation of the dish is basically dependent on cooks of various restaurants, is completely manual, is difficult to meet huge market demands, and has different dish quality due to the difference of cooking skills of the cooks.
The fish meat cutting in the existing pickled Chinese cabbage fish processing is limited to manual operation, the size and thickness of the fish fillet are difficult to ensure the height consistency, and the fish fillet processing method wastes time and labor. The food and beverage shop cuts the flesh of fish and all accomplishes by hand, and fillet thickness, size are uneven, and consuming time is hard, and is inefficient, and the improvement to flesh of fish taste relies on producer's personal experience moreover, is difficult to guarantee the stability of flesh of fish taste. The conventional method for processing fish meat in restaurant includes the steps of pickling, whipping, adding starch and egg white for sizing, processing the fish meat, mastering the duration and degree of heating by the experience of a cook during cooking, controlling the duration and degree of heating to obtain the fish meat with tender and smooth mouthfeel, slightly deviating each link of the cook in the whole manufacturing process, making the fish meat into dish with the mouthfeel of firewood and dregs, losing the main characteristics of the dish, and making the dish with the characteristic and flavor well, timely and unstable. The taste of the dish soup after the dish is finally prepared is obviously different due to different raw material sources and different batches of dish ingredients (pickled vegetables and seasonings).
