Abstract

The invention belongs to the technical field of aquatic product processing, and particularly relates to a preparation method of refrigerated fresh-keeping flavored crayfishes. By means of the method,the storage period of the crayfishes can be prolonged, the meat of the refrigerated crayfishes still keeps high protein content and elasticity, the good taste is maintained, and a longer crayfish storage and transportation period is provided for families or production industries. The method is characterized in that fresh crayfishes are placed in clear water for temporary breeding; the crayfishes are fished out and placed in an aqueous solution of acetic acid, semen cassiae, broad bean powder and gleditsia sinenis lam gum are added into the aqueous solution and mixed uniformly, and the crayfishes are completely submerged in water, cooled, frozen into blocks and refrigerated for storage; the refrigerated crayfish ice blocks are unfrozen, and the crayfishes are thoroughly washed and brushed with clear water; the crayfishes are put into a vacuum fryer for deep frying; the crayfishes are fished out and poured into a hot oil pot, seasonings are added, and stir frying is carried out; sauce ispoured into the pot, braising is conducted for 2-3 min, and the crayfishes can be taken out of the pot.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a preparation method of refrigerated and fresh-keeping flavored crayfish. Background technique [0002] Crayfish, scientific name Procambarus clarkii, also called red crayfish, is a crustacean that lives in fresh water and is widely distributed in various provinces and cities in the middle and lower reaches of the Yangtze River. Crayfish have an absolute competitive advantage in the local ecological environment due to their omnivorous nature, fast growth speed, and strong adaptability. Crayfish are delicious and nutritious, and are very popular among consumers. [0003] However, since crayfish itself contains a variety of proteases, they can also autolyze under low temperature conditions, which makes it difficult to store crayfish in cold storage. The quality of crayfish begins to change after 6-8 hours of storage at 5°C, which greatly limits the q...
