preparation example Construction

[0048] The preparation method of the hairtail protein peptide powder comprises the following steps:

[0049] (1) Pretreatment: Wash the hairtail, remove the head, tail, and viscera, and remove the hairtail bones to leave the hairtail meat. Mix the hairtail meat and water according to the water-to-material ratio of 1:3, and use an electric high-speed tissue grinder Stir into hairtail meat mince, set aside;

[0050] (2) Enzymolysis: add alkaline protease to 1.6% of the weight of hairtail minced meat obtained in step (1), and enzymolyze it in a water bath at 50° C. for 4 hours to obtain an enzymolysis solution;

[0051](3) Enzyme inactivation: raise the temperature of the water bath to 90°C, keep the temperature constant, and inactivate the enzyme solution obtained in step (2) in the water bath for 15 minutes;

[0052] (4) Centrifugation and filtration: the enzymatic hydrolysis solution after the enzyme-inactivating treatment in step (3) is centrifuged at 4000r / min and 4°C for 2...

[0057] A. Raw material pretreatment

[0058] Fresh milk pretreatment: filter with a 100-200-mesh sieve, pasteurize at 80°C-95°C, and filter again with a 100-200-mesh sieve after cooling;

[0059] Lemon pretreatment: select pesticide-free and non-rotten lemons, wash them, squeeze the juice through a juicer, and filter through a sieve to obtain lemon juice;

Abstract

The invention discloses a hairtail protein peptide nutrient milk powder and a preparation method thereof. The hairtail protein peptide nutrient milk powder comprises the following components in partsby weight: 85-90 parts of fresh milk, 2-5 parts of glucose, 2.5-4.5 parts of hairtail protein peptide powder, 0.1-0.2 part of soybean phosphatide, 0.002-0.01 part of bifidobacterium, 0.4-0.5 part of fructo-oligosaccharide, 1-8 parts of galactooligosaccharide and 0.2-1 part of lemon juice. According to the invention, hairtail protein peptides are added into the milk powder so as to improve the nutritional value of the milk powder, guarantee that the prepared milk powder has original milk nutrients, and guarantee that the prepared milk powder has the efficacy of enhancing resistance and resisting oxidation. In addition, the lemon juice is added to the milk powder to ensure the mouth feel of the milk powder.

Description

technical field [0001] The invention relates to the technical field of dairy processing, in particular to hairtail protein peptide nutritional milk powder and a preparation method thereof. Background technique [0002] In recent years, with the development of science and technology, biological small molecule peptide products such as collagen peptides and marine oligopeptides have gradually been recognized by the general public for their good biological nutrition and health care functions. Small molecular biological peptides are widely used in health care, food, medicine and other fields because of their small molecular weight (average molecular weight less than 3000D), easy absorption by the body, and remarkable nutritional and health effects. [0003] Hairtail, also known as saury and octopus, is an animal of the order Perciformes hairtail. It is a kind of economic fish with high production in my country's coastal areas. It is delicious and deeply loved by consumers. Hairt...
