Problems solved by technology

[0002] Eating raw fish or raw fish fillets is a habit of human beings in ancient times. From a nutritional point of view, raw fish or raw fish fillets are raw foods that have not undergone traditional cooking treatments such as frying, frying, steaming, and boiling (that is, without heating to make protein Denaturation and solidification process) of raw fish or sashimi, because its nutrients do not lose at all, is a very nutritious delicacy, more and more popular, but the main problems of raw fish or raw fish at present: One is from a hygienic point of view, if raw fish or fish fillets are not properly processed, they are prone to bacterial infection, spoilage and deterioration, which will become the source of infectious diseases for people; Although it can keep fresh for a long time, it also makes the taste or mouthfeel of fish worse; the third is that it is not convenient for long-distance long-distance transportation under the premise of ensuring unique flavor, and it cannot solve the problem of fresh-keeping technology and cause waste of food resources.

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 :

[0023] The physical fresh-keeping method of raw fish meat or fish fillets is realized by the following steps:

[0024] (1) Choose live fish that are non-toxic and harmless and can be eaten raw, and feed the live fish hungry for 2 days;

[0025] (2) Slaughtering and processing in a sterile and low-temperature special workshop: stun live fish that have been starved for 1-2 days by electric shock or carbon monoxide, remove gills and drain blood, remove viscera, fins, skin, and head , remove the tail, remove the bone, take the fish meat and rinse it with sterile water, hang the fish meat and blow off the water on the surface of the fish meat with cool wind, and sterilize it with ultraviolet rays. Put it into a box and pack it in a vacuum, then immerse it in non-freezing zero-degree water for 10-30 minutes, so that the central temperatu...

Abstract

The invention belongs to the technical field of freshness preservation of fish products, and relates to a physical freshness preservation method of uncooked fish meat or fish fillets. The physical freshness preservation method comprises the steps as follows: firstly, innocuous and unpoisonous fresh fish which can be eaten crudely are selected and cultivated for 1-2 days without food; secondly, the fresh fish is killed, processed, electrically stunned, subjected to gill removing and bloodletting, and manufactured into a non-frozen vacuum-packed fish product at the temperature of zero DEG C in a special sterile low-temperature workshop; and thirdly, the manufactured vacuum-packed fish product is placed in a bubble chamber with an ice bag at the temperature lower than zero DEG C for freshness preservation. The physical freshness preservation method of the uncooked fish meat or the fish fillets has the advantages as follows: the fish product is nutrient-rich, safe, hygienic, good in taste and convenient to transport, the freshness preservation time is longer than 72 hours, the freshness preservation belongs to purely physical and anhydrous freshness preservation, any chemical substances are not added, and the method is applicable to processing and freshness preservation for uncooked fish.
