Penaeus Vannamei ice temperature fresh keeping method combining with ice cube refrigeration

Abstract

The invention discloses a Penaeus Vannamei ice temperature fresh keeping method combining with ice cube refrigeration. The method comprises the following steps: 1, preparing a biological fresh keeping agent solution, and dividing it into two parts; 2, preparing ice cubes from one part of the biological fresh keeping agent solution by an ice making machine; 3, flushing screened Penaeus Vannamei bodies by sterile water, cooling the Penaeus Vannamei bodies by crushed ice for 5-10min, and immersing the cooled Penaeus Vannamei bodies in the biological fresh keeping agent solution for 1-3min; 4, putting the ice cubes containing the biological fresh keeping agent in a stainless steel cylinder to realize a case that the Penaeus Vannamei bodies are surrounded by the ice cubes; 5, covering Penaeus Vannamei surfaces with a small amount of the crushed ice to fully cover Penaeus Vannamei by the ice cubes; 6, storing the stainless steel cylinder in a 2-8DEG C refrigerator; and 7, timely supplying the ice cubes containing the biological fresh keeping agent during the storage. Compared with the storage which is carried out only under pure water ice cube refrigeration conditions, the fresh keeping agent allows the shelf life of Penaeus Vannamei to be obviously prolonged by 7-8 days. The fresh keeping method of the invention, which is simple and easy to carry out, can accurately realize the ice temperature control and has a good fresh keeping effect, has a very good application value.

Description

technical field [0001] The invention relates to the technical field of biological fresh-keeping of food and medicine, in particular to the field suitable for fresh-keeping of Penaeus vannamei, and relates to an ice-temperature fresh-keeping method for refrigerating Penaeus vannamei by combining ice cubes. Background technique [0002] Penaeus vanmamei is a creature native to the waters of the Pacific coast of South America. Since it was introduced in my country in the 1990s, its production scale has continued to expand, and it has now become the country with the largest breeding area and the highest output in the world. . Penaeus vannamei is rich in protein, low in fat, and delicious in meat quality. It is very popular with consumers. However, Penaeus vannamei is a perishable food. During fishing, transportation, processing and storage, the solution turns black and spoils, reaching the consumption level. The situation is unacceptable to the marketers, resulting in a great wa...

Problems solved by technology

[0006] 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 from people, 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 Penaeus vannamei
