Embodiment 1

[0025] A small fish protein powder, the small fish protein powder is composed of the following raw materials by weight: 100 parts of small fish extract, 50 parts of vegetable powder, 80 parts of maltodextrin, 20 parts of fruit powder, and 10 parts of auxiliary agents 40 servings with bone meal.

[0026] The preparation method of the small trash fish extract includes the following steps: selecting fresh or frozen small trash fish by 0-4° C., removing the fish head, fish tail, fish fins and fish bones and homogenizing to obtain fish paste, and mashing the fish. The pulp was soaked in the soaking liquid for 30min at 75°C, and ultrasonically treated at the same time. After being taken out, it was rinsed with a citric acid ice solution with a mass concentration of 1.7% for 30min. After washing with water, add 30-40U / g of Lipase, at 30 ° C, enzymatic hydrolysis for 60 min to obtain a degreasing homogenate; add proteolytic enzyme to the degreasing homogenate, and after the enzymatic ...

Embodiment 2

[0030] A small fish protein powder, the small fish protein powder is composed of the following raw materials by weight: 110 parts of small fish extract, 60 parts of vegetable powder, 90 parts of maltodextrin, 25 parts of fruit powder, and 15 parts of auxiliary agents 50 servings with bone meal.

[0031] The preparation method of the small trash fish extract includes the following steps: selecting fresh or frozen small trash fish by 0-4° C., removing the fish head, fish tail, fish fins and fish bones and homogenizing to obtain fish paste, and mashing the fish. The pulp was soaked in the soaking solution for 40min at 80°C, and ultrasonically treated at the same time. After being taken out, it was rinsed with a 2% citric acid ice water solution for 60min. After washing with water, add 30-40U / g of Lipase, at 32 °C, enzymatic hydrolysis for 70 min to obtain a defatted homogenate; add proteolytic enzyme to the defatted homogenate, and after the enzymatic hydrolysis is completed, the...

Embodiment 3

[0035] A small fish protein powder, the small fish protein powder is composed of the following raw materials by weight: 120 parts of small fish extract, 80 parts of vegetable powder, 100 parts of maltodextrin, 30 parts of fruit powder, and 20 parts of auxiliary agents 60 servings with bone meal.

[0036]The preparation method of the small miscellaneous fish extract includes the following steps: select fresh small miscellaneous fish or small miscellaneous fish that have been thawed in running water at 0-4°C, remove fish heads, fish tails, fish fins and fish bones and homogenize to obtain fish paste, and fish Soak the pulp in the soaking solution at 100°C for 60 minutes, and at the same time perform ultrasonic treatment, rinse it with 2.2% citric acid ice water solution for 80 minutes, add 40 U / g lipase to the fish paste after washing , under the condition of 35°C, enzymolysis treatment for 75 minutes to obtain a degreasing homogenate; add proteolytic enzymes to the degreasing h...

Abstract

The invention relates to trash fish protein powder. The trash fish protein powder is prepared from the following raw materials in parts by weight: 100-120 parts of a trash fish extract, 50-80 parts of vegetable powder, 80-100 parts of maltodextrin, 20-30 parts of fruit powder, 10-20 parts of an addition agent and 40-60 parts of bone meal. The trash fish disclosed by the invention is subjected to mild enzymolysis, so that generation of toxic substances can be avoided; the trash fish protein powder is rich in micromolecular protein, bioactive peptide, amino acids, nucleotide, vitamins and trace elements; the trash fish protein powder can be made into nutritive health-care products, leisure foods and conditioning products, the product quality is improved, and the value of the trash fish is developed; the trash fish protein powder product is simple in preparation technology, low in cost, short in making time and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of health food, in particular to a small fish protein powder with anti-oxidation, scavenging free radicals and improving immunity. Background technique [0002] With the development of aquaculture and marine fishing, the output of aquatic products in my country is increasing, with an annual output of more than 10 million tons, of which more than 20% are low-value small trash fish. The conventional method of processing low-value small trash fish in my country is to dry it to prepare fish meal as a feed additive, and its added value is not high. In coastal areas, some fishermen marinate low-value small trash fish and ferment them naturally to make fish sauce. Both the quality and the application range are quite limited. The nutritional components of low-value small trash fish are not much different from those of high-quality fish, and the protein content is rich and excellent protein. my country is a country w...
