Abstract

The invention discloses a fish block non-freezing fresh-keeping method combining decontamination pretreatment with modified atmosphere packaging, and belongs to the technical field of aquatic productprocessing and storage. The preparation method comprises the following steps: S1, pretreating whole fish, taking fish meat and dicing the fish meat into blocks; S2, putting the fish blocks into a decontamination solution for soaking; S3, performing modified atmosphere packaging; and S4, performing non-freezing storage. According to the fish block non-freezing fresh-keeping method combining decontamination pretreatment with modified atmosphere packaging, the decontamination can significantly reduce the number of putrefying bacteria in fish meat at the initial storage stage, and quality of fishblocks subjected to decontamination treatment is not affected; the modified atmosphere packaging can further inhibit the growth of putrefying bacteria in the storage process and improve the freshnessof the fish blocks, so that the shelf life of the fish blocks is prolonged. The method is convenient to apply and safe to operate, is low in production cost and is suitable for fresh-keeping storage of fresh fish blocks.

Description

technical field

[0001] The invention belongs to the technical field of aquatic product processing and storage, and in particular relates to a non-frozen and fresh-keeping method for fish nuggets combined with pretreatment for bacteria reduction and modified atmosphere packaging. Background technique

[0002] Fish is one of the main sources of animal protein for humans. Compared with livestock meat, fish meat has high water content, rich endogenous enzyme content, and loose texture, so fish meat deteriorates quickly. The shelf life of fish meat stored under non-frozen conditions is much shorter than that of livestock meat. my country is a major producer of aquatic products, and fish production accounts for almost half of the total aquatic product production. Chinese consumers have always preferred fresh fish. Freshwater fish in the Chinese market is mainly sold in the form of fresh whole fish, while seawater fish is mainly sold in the form of frozen or chilled fresh whole fi...
