AI Technical Summary

Problems solved by technology

The level of deep processing and utilization of channel catfish in my country is extremely low
During the processing of channel catfish, a large amount of leftovers - fish skin, fish bones, fish heads, fish viscera and other leftovers, which account for about 35%-55% of the total mass of the fish body and are only discarded as waste or processed Feed fishmeal has a low utilization rate, and these by-products are rich in protein and minerals and other nutrients

Embodiment 1

[0013] The raw material is frozen channel catfish bones, which are thawed, rinsed and drained.

[0014] (1) Minced meat: Use alkaline protease to enzymatically remove the residual muscle on the fish bones. The enzymatic hydrolysis conditions are: the enzymatic hydrolysis temperature is 40°C, the enzymatic hydrolysis time is 150min, the enzymatic hydrolysis pH is 7, and the enzyme activity used is 1500U / g, the ratio of solid to liquid is 1:1.

[0015] (2) Pulverization: The bone meal coarsely crushed by the crusher is ground with a colloid mill. When grinding, add bone meal first, and then add water after grinding for a period of time. The amount of water and bone meal added is 1:5. After the water is wet, add the rest of the water. After grinding for 7 minutes, open the discharge port to release the bone paste.

[0016] Package, seal and sterilize to make finished bone paste. The product is white and delicate, relatively viscous.

Embodiment 2

[0018] The raw material is frozen channel catfish bones, which are thawed, rinsed and drained.

[0019] (1) Minced meat: Use alkaline protease to enzymatically remove the remaining muscle on the fish bones. The enzymatic hydrolysis conditions are: the enzymatic hydrolysis temperature is 70°C, the enzymatic hydrolysis time is 60min, the enzymatic hydrolysis pH is 11, and the enzyme activity used is 1000U / g, the ratio of solid to liquid is 1:5.

[0020] (2) Pulverization: The bone meal coarsely crushed by the crusher is ground with a colloid mill. When grinding, add bone meal first, and then add water after grinding for a period of time. The amount of water and bone meal added is 2:1. After the water is wet, add the rest of the water. After grinding for 2 minutes, open the discharge port to release the bone paste.

[0021] Package, seal and sterilize to make finished bone paste. The product is white and delicate, with a slightly low viscosity.

Embodiment 3

[0023] The raw material is frozen channel catfish bones, which are thawed, rinsed and drained.

[0024] (1) Minced meat: Use alkaline protease to enzymatically remove the residual muscle on the fish bones. The enzymatic hydrolysis conditions are: the enzymatic hydrolysis temperature is 60°C, the enzymatic hydrolysis time is 100min, the enzymatic hydrolysis pH is 9, and the enzyme activity used is 1200U / g, the ratio of solid to liquid is 1:2.

[0025] (2) Pulverization: The bone powder coarsely crushed by the crusher is ground with a colloid mill. When grinding, add bone powder first, and then add water after grinding for a period of time. The amount of water and bone powder added is 1:2. After the water is wet, add the rest of the water. After grinding for 5 minutes, open the discharge port to release the bone paste.

[0026] Package, seal and sterilize to make finished bone paste. The product is white and delicate, with moderate viscosity.

Abstract

The invention relates to a method for preparing bone paste by using Ictalurus punctatus bone, pertaining to the technical field of the comprehensive utilization of the Ictalurus punctatus. The method takes frost fishbone as a raw material to prepare the finished bone paste product through thawing, rinsing, draining, enzymolysis meat removing, smashing, grinding, packaging, sealing and sterilizing. The calcium content of the Ictalurus punctatus bone can reach 4150mg / 100g. The Ictalurus punctatus bone is utilized to produce the bone paste, thus increasing the processing added value and promoting the comprehensive utilization rate of freshwater fish.

Description

technical field [0001] The invention discloses a method for preparing bone paste from channel catfish bones, which belongs to the technical field of comprehensive utilization of channel catfish. Background technique [0002] At present, CaCO is mainly added to calcium supplement foods. 3 And other inorganic calcium, the human body absorption rate is low, and there is a certain proportion of calcium and phosphorus in human bones, excessive simple calcium supplementation is also unfavorable to the human body. Bone is the largest storage place for calcium phosphate, magnesium carbonate, magnesium phosphate, calcium fluoride, etc. in the animal body. The calcium content in bone is very high, and the ratio of calcium to phosphorus is also very reasonable, which is the best ratio in the body. Fishbone is the general term for the axial bone, appendage bone and fishbone of the fish body. Fish bones contain protein, water, fat and rich organic calcium, phosphorus and other trace el...
