Canned fish capable of being preserved at normal temperature

Abstract

The invention discloses a fish can capable of being preserved at normal temperature, and particularly relates to the field of food processing.The fish can comprises a can body, a top cover is fixedly arranged at the top of the can body, the periphery of the top cover is fixedly connected with the inner wall of an opening in the top end of the can body, a pull ring is fixedly arranged on the top cover, and a built-in bag is arranged in an inner cavity of the can; the tin can body comprises a can shell, a containing cavity is formed in the can shell, a heat insulation pad is arranged in the containing cavity, the built-in bag comprises fish meat materials, a sealing bag is arranged outside the fish meat materials, and the sealing pad and the fish meat materials are sealed through vacuumizing. According to the invention, through the arrangement of the double-layer can box body, the heat insulation pad is used for insulating the external temperature, then the prepared fish meat material is subjected to vacuum-pumping sealed storage by using the sealing bag, and then the steps of sterilization treatment, drying and canning are performed, so that the storage time of the canned fish is greatly prolonged; therefore, the preservation effect is ensured in a normal temperature state.

Description

technical field [0001] The invention relates to the technical field of food processing, and more specifically, the invention relates to a canned fish that can be stored at room temperature.

Problems solved by technology

[0003] Processing fish meat into canned fish can greatly extend the storage time of fish meat. However, the existing canned fish needs to be placed in the refrigerated layer of the refrigerator during storage, and cannot be placed directly indoors at room temperature, otherwise it will cause fish The shortened storage time of canned food is not conducive to the storage of canned fish
