Embodiment 1

[0015] For the production process of high-quality freshwater fish surimi, see figure 1 , including the following steps:

[0016] 1. Preparation of grass carp surimi: slaughter the grass carp, remove the viscera and head, wash it, use a meat harvester to harvest the meat, collect the minced fish meat and fish bones separately, add ice to cool the machine before harvesting the meat, and keep stirring during the meat harvesting process. Add ice to reduce the temperature of the fish meat; use the fine filter machine to extract the finely mined fish meat, and at the same time add ice to keep the temperature low; add 4-6 times the amount of cooling water to the finely filtered minced fish meat for rinsing, and the cooling water is 10 Below ℃, slowly stir for 2-5 minutes during the rinsing process, let it stand for 6-10 minutes, pour off the surface rinsing solution, and filter it with gauze; repeat the rinsing again; dehydrate with a centrifuge, and the water content of the surimi i...

Embodiment 2

[0021] Select silver carp as raw material, the addition of fish bone meal is 5.0%, all the other steps are with embodiment 1, and this example is compared with the silver carp surimi that does not add fish bone meal, and yield improves about 5.0%, increases calcium content in product At the same time, the surimi gel strength can be increased by 5.0%.

Embodiment 3

[0023] Select bighead carp as raw material, the addition of fish bone meal is 3.5%, and all the other steps are the same as in Example 1. Compared with the bighead carp surimi without adding fish bone meal, the yield is increased by about 3.5%, and the calcium content in the product is increased. At the same time, the surimi gel strength can be increased by 12%.

Abstract

The invention discloses a processing method of high-quality freshwater fish paste. The method comprises the following concrete steps: rinsing freshwater fish meat twice and dewatering; and adding 1.0%-5.0% of fish bone powder and an anti-freezing agent, quickly freezing and storing at -18 DEG C, wherein the fish bone powder is prepared by processing fish bones through a colloid mill and has the particle size being 0.08mm-0.14mm. According to the method, the fish bone powder is added, so that the yield of the fish paste can be increased, the content of calcium in the fish paste can be increased, the nutritional value of the fish paste can be improved, the jelly strength of the fish paste can be enhanced by 5%-15%, and the quality of the freshwater fish paste can be improved.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, and relates to a processing method for producing high-quality freshwater surimi by using low-value freshwater fish. Background technique [0002] Surimi processing technology is the most widely used high-tech in the world's aquatic product processing industry. Among all the deep processing technologies of aquatic products, surimi processing technology has the best adaptability to raw fish, and the most common freshwater fish, easy to breed, high yield, and low economic value fish species are suitable for freshwater fish surimi processing, such as white Silver carp, bighead carp, grass carp, carp, tilapia, herring, etc. The use of high-yield and low-priced freshwater raw fish to process surimi not only improves the processing capacity and technical level, but also can make up for the shortage of raw materials for surimi processing caused by the large reduction of marine fishery resources...
