Embodiment 1

[0017] 1) Pretreatment: Remove the viscera, scales and gills of the small miscellaneous fish and mince them into surimi, add water, grind them into fish homogenate, and the ratio of surimi:water volume is 1:20~40;

[0018] 2) Degreasing: Add phospholipase A1 and phospholipase A2 to fish homogenate for enzymatic hydrolysis. The amount of phospholipase A1 and phospholipase A2 added is 0.1-0.4% and 0.3-0.7% of the volume of fish homogenate, respectively. The enzymatic hydrolysis temperature is 35-45°C, the pH is 8-9, and the enzymatic hydrolysis time is 7-13 minutes. Phospholipase A1 and phospholipase A2 act on the fat in the fish homogenate, break the carbon-oxygen single bond in the fat, and decompose the fat. After enzymatic hydrolysis, the enzyme is inactivated, and an organic solvent is added, the organic solvent is a mixture of acetone and ethanol, the volume ratio is 1:1~3, and the volume ratio of fish homogenate to organic solvent is 1:2~3. Using the principle of simila...

Embodiment 2

[0025] 1) Pretreatment: Remove the viscera, scales and gills of small miscellaneous fish, mince them into surimi, add water, grind them into fish homogenate, and the volume ratio of surimi:water is 1:35;

[0026]2) Degreasing: Add phospholipase A1 and phospholipase A2 to fish homogenate for enzymatic hydrolysis. Phospholipase A1 and phospholipase A2 were added in amounts of 0.3% and 0.6% of the volume of the fish homogenate, respectively. The enzymolysis temperature is 40° C., the pH is 8.6, and the enzymolysis time is 10 minutes. Phospholipase A1 and phospholipase A2 act on the fat in the fish homogenate, break the carbon-oxygen single bond in the fat, and decompose the fat. After enzymatic hydrolysis, the enzyme is inactivated, and an organic solvent is added. The organic solvent is a mixture of acetone and ethanol with a volume ratio of 1:2, and the volume ratio of fish homogenate to organic solvent is 1:2.8. Using the principle of similar compatibility, the remaining fat...

Embodiment 3

[0033] 1) Pretreatment: remove the viscera, scales and gills of small miscellaneous fish, mince them into surimi, add water, grind them into fish homogenate, and the volume ratio of surimi:water is 1:40;

[0034] 2) Degreasing: Add phospholipase A1 and phospholipase A2 to fish homogenate for enzymatic hydrolysis. Phospholipase A1 and phospholipase A2 were added in amounts of 0.2% and 0.6% of the volume of the fish homogenate, respectively. The enzymolysis temperature is 40° C., the pH is 8.6, and the enzymolysis time is 10 minutes. Phospholipase A1 and phospholipase A2 act on the fat in the fish homogenate, break the carbon-oxygen single bond in the fat, and decompose the fat. After enzymatic hydrolysis, the enzyme is killed, and an organic solvent is added. The organic solvent is a mixture of acetone and ethanol with a volume ratio of 1:2.6, and the volume ratio of fish homogenate to organic solvent is 1:2.1. Using the principle of similar compatibility, the remaining fat i...

Abstract

The invention discloses a processing method of a protein powder product from small trash fishes, and the processing method comprises the operation steps: 1) pretreatment; 2) degreasing; 3) enzymolysis; 4) deodorization; 5) ultrafiltration; 6) desalting; and 7) spray drying. The processing method of the protein powder product from small trash fishes has the beneficial effects: the processing method takes the small trash fishes as the raw material, has low cost, increases a treatment route for the low-value small trash fishes, carries out reasonable application of resources and increases the added value of the small trash fishes; the prepared protein powder from the small trash fishes has small molecular weight, is easy to digest and absorb by a human body, and has no fishy smell, high purity and activity of protein, and excellent product quality; during enzymolysis, infrared temperature control is adopted, thereby greatly shortening the production cycle and reducing the time cost and manpower cost; and the processing method is simple, high in reproductivity and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for processing small miscellaneous fish protein powder products. Background technique [0002] With the development of aquaculture and marine fishing, the output of aquatic products in my country is increasing continuously, with an annual output of more than 10 million tons, of which more than 20% are low-value small miscellaneous fish. The conventional method of dealing with low-value small trash fish in my country is to dry it and prepare it as feed additive fish meal, which has low added value. In coastal areas, some fishermen pickle low-value small trash fish and naturally ferment them to make fish sauce. Both the quality and the scope of application are quite limited. The nutritional composition of low-value small trash fish is not much different from that of high-quality fish, and the protein content is rich and high-quality protein. my country is a country...
