Embodiment 1

[0018] A small miscellaneous fish protein powder product is prepared from small miscellaneous fish through pretreatment, degreasing, enzymatic hydrolysis, deodorization, ultrafiltration, desalination and spray drying.

[0019] 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;

[0020] 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 inactiva...

Embodiment 2

[0027] A small miscellaneous fish protein powder product is prepared from small miscellaneous fish through pretreatment, degreasing, enzymatic hydrolysis, deodorization, ultrafiltration, desalination and spray drying.

[0028] 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;

[0029]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 add...

Embodiment 3

[0036] A small miscellaneous fish protein powder product is prepared from small miscellaneous fish through pretreatment, degreasing, enzymatic hydrolysis, deodorization, ultrafiltration, desalination and spray drying.

[0037] 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;

[0038] 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. ...

Abstract

The present invention discloses a small coarse fish protein powder product. The small coarse fish protein powder product is prepared by small coarse fish pretreating, degreasing, enzymolyzing, deodorizing, ultra-filtering, desalting and spray drying. Beneficial effects are as follows: the small coarse fish is used as a raw material and cheap in costs, a treatment method of the low-value small coarse fish is increased, the resource is reasonably applied and an added value of the small coarse fish is increased. The prepared small coarse fish protein powder is small in molecular weight, easy for digestion and absorption by human body, free of smelly smell, high in purity and activity of proteins, and excellent in product quality. During the enzymolyzing, an infrared temperature control is used, a production cycle is greatly shortened, time costs and labor costs are reduced, and a processing method is simple, high in reproducibility and suitable for mass productions.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a small miscellaneous fish protein powder product. 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 with a relative shorta...
