Problems solved by technology

In this method, high-pressure heat treatment has the disadvantages of high cost and easy oxidation loss of unsaturated fatty acids
[0008] The unsaturated fat content of fish belly meat is high, and it is easy to oxidize to produce fishy smell during storage. Therefore, in the process of surimi processing, in order to ensure the stability of the product, the fish belly meat is often cut off and discarded, resulting in a lot of waste

Abstract

The invention provides a production method for fish head paste rich in polyunsaturated fatty acid. The production method comprises the following steps: firstly, fish heads without gills are cleaned, crushed and added with a fishy smell elimination agent, homogenating is carried out, the pH value is adjusted to be less than or equal to 3.0, stirring and pumping filtration are carried out, the filtrate is collected, and fish head paste without fishbone is obtained; secondly, fish maw flesh is cleaned and added with the fishy smell elimination agent, homogenating and filtering are carried out, and fish maw flesh paste is obtained; thirdly, the fish head paste without fishbone and the fish maw flesh paste are taken at a mass ratio of 1:0-0.4 and mixed uniformly, a stabilizing agent and an emulsifier are added, the pH value is adjusted to 3.5-4.5, homogenating is carried out, and mixed fish flesh paste is obtained; fourthly, seasoners are added, the mixture is mixed uniformly, loading and disinfection are carried out and fish head paste is obtained. The production technology is simple, the cost is low, and the method is suitable for industrial production. The fish head paste product has a high unsaturated fatty acid content and has rich nutrients, the TBARS value is low, the fish head paste has no fishy smell and has a good special flavor.

Description

technical field [0001] The invention relates to a production method of fish head paste, in particular to a production method of fish head paste rich in polyunsaturated fatty acids. Background technique [0002] The composition of freshwater fish is relatively special, and the proportion of the fish head is relatively large, and some are about 1 / 4 to 1 / 3 of the weight of the whole fish. At present, only the heads of bighead carp are consumed in large quantities, while the heads of other fish are often discarded directly because of their small size and less meat, or used for processing feed and fertilizer, resulting in waste of resources and high processing costs for freshwater fish. [0003] Fish head is rich in nutrients, such as protein, fat, calcium, phosphorus, iron, vitamin B1, etc. Among them, the content of polyunsaturated fatty acids in fat is very high, such as EPA and DHA, which are extremely important for the development of the brain. Fish head is very beneficial ...
