Puffer fish preserving ice-temperature method

Abstract

The invention discloses a puffer fish preserving ice-temperature method. The puffer fish preserving ice-temperature method comprises the steps as follows: 1, preparing a biological preserving agent solution and dividing the biological preserving agent solution into two parts; 2, preparing one part of the biological preserving agent solution into ice blocks by an ice making machine; 3, killing bought fresh live puffer fish, removing the head and inner organs, cutting the puffer fish into pieces, rinsing the puffer fish pieces by sterile water, cooling the puffer fish pieces by crushed ice blocks for 15-30 minutes, and soaking the cooled puffer fish into the biological preserving agent solution for 1-3 minutes; 4, putting the ice blocks containing the biological preserving agent solution into a square stainless steel barrel, so that the puffer fish is surrounded by the ice blocks; 5, covering the surface of the puffer fish with a small quantity of crushed ice, so that the puffer fish iscovered sufficiently by the ice blocks; 6, putting the square stainless steel barrel into a refrigerating cabinet with the temperature of 2-8 DEG C for storing; and 7, supplementing the ice blocks containing the biological preserving agent solution in good time during the storage. Compared with the storage of the puffer fish under the storage conditions with purified water and the ice blocks, thepreserving agent can obviously prolong the shelf life of the puffer fish by 8-9 days; and the puffer fish preserving ice-temperature method is simple and feasible in operation, good in preserving effect and has good application value.

Description

technical field [0001] The invention relates to the technical field of food and drug biological fresh-keeping, in particular to the field suitable for keeping puffer fish fresh, and relates to an ice-temperature fresh-keeping method for refrigerating puffer fish combined with ice cubes. Background technique [0002] Puffer fish, also known as puffer fish, is a kind of fish whose internal organs contain tetrodotoxin, and there are hundreds of species. Although the tetrodotoxin in puffer fish is very toxic, its meat is delicious, delicate and delicious, with high nutritional value and endless aftertaste. There are more than 40 species of puffer fish produced in my country, and China has become a major producer and marketer of puffer fish in the world. However, puffer fish is a perishable food, which is extremely susceptible to bacterial attack and spoilage during fishing, transportation, processing and storage, thereby causing a huge waste of resources and making puffer fish ...

Problems solved by technology

[0005] The cold storage time is short, and the spoilage is fast; although the freshness index can be maintained for a long time in frozen storage, the physical and chemical indicators are severely reduced, and the loss of nutrients is intensified, especially the loss of nutrients caused by the thawing process is serious.

The increasingly popular ice temperature preservation technology is getting more and more attention, but it is difficult to accurately control the temperature of the ice temperature process. There are certain temperature fluctuations in the existing refrigeration equipment, and the temperature fluctuation is very unfavorable to the preservation of puffer fish.
