591 results about "Dried fish" patented technology

Fresh fish rapidly deteriorates unless some way can be found to preserve it. Drying is a method of food preservation that works by removing water from the food, which inhibits the growth of microorganisms. Open air drying using sun and wind has been practiced since ancient times to preserve food. Water is usually removed by evaporation (air drying, sun drying, smoking or wind drying) but, in the case of freeze-drying, food is first frozen and then the water is removed by sublimation. Bacteria, yeasts and molds need the water in the food to grow, and drying effectively prevents them from surviving in the food.

Fish processing method

The invention provides a fish processing method, which is to use salts to pickle fish. The whole technological process of pickling is as follows: firstly, drying the fish at a temperature of less than 16 DEG C until the water content is between 28 and 32 weight percent; secondly, dividing common salts which account for 12 to 15 weight percent of dried fish into two parts, spreading one part of the common salts at the bottom of a pickling container, spreading the dried fish on a salt layer to form a layer one by one, and spreading the other part of the common salts on a fish layer and making the common salts completely cover fish bodies; thirdly, applying pressure on the common salt layer on the fish, wherein the pressure is between 0.1 and 0.2 kPa; and fourthly, placing the fish for 6 to 9 days in a room at the temperature of between 2 and 4 DEG C. Compared with the prior art, the fish processing method has simple processing technique, convenient operation and low equipment cost, and the processed salted fish has rich nutrition, proper salinity and long storage period. Moreover, the fish processing method overcomes the defects of heavy taste of the conventional salted fish, complex processing technique and containing of a nitrite composition, and simultaneously solves the problem of mutual contradiction of the taste and the storage period.
