Embodiment 1

[0029] A method for producing pharmaceutical-grade protein peptide powder using salmon as a raw material, characterized in that the method comprises the following steps:

[0030] S1. Raw material preparation

[0031] Select 1,500 kg of high-quality salmon frozen minced meat, fish steaks and fish skin as raw materials. It is required that the volatile base nitrogen of salmon raw materials is less than 40, and the raw materials are crushed to 0.5 ~ 1.5cm pieces, put into 10m 3 In the hydrolysis still, add fresh soft water to 4 times of raw material weight. In the process of preparing the above-mentioned raw materials, fresh salmon meat and fish bones can also be used as raw materials. The amount of soft water added in the hydrolysis kettle is controlled between 3-4 times that of solids, and the specific value can be flexibly controlled according to the water content of raw materials;

[0032] S2, the first step of enzymatic hydrolysis

[0033] Add endonuclease to the reaction...

Abstract

The invention belongs to the technical field of bioengineering, and provides a method for producing pharmaceutical-grade protein peptide powder by taking salmon as a raw material in order to solve the technical problems existing in the process of extracting and purifying protein peptide powder by taking the salmon as the raw material. The method comprises the steps that by means of comprehensive application of endonuclease and exonuclease, zymolyte is subjected to secondary enzymolysis, three-time filtration and standing; the obtained protein peptide powder can completely meet index requirements of the pharmaceutical-grade protein peptide powder and serve as the raw material of medical grade peptone, health-care product grade fish protein powder and compound amino acid powder.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of bioengineering, and in particular relates to a method for producing medical-grade protein peptide powder using salmon as a raw material. [0003] technical background: [0004] Protein peptide powder is not only an important nitrogen nutrient source for the medium used in the fermentation pharmaceutical industry, but also an important raw material for adding food and health products and compound amino acids. In the past, medical-grade protein peptide powder mainly used peptone, mainly beef extract, fish soluble pulp powder, etc., but as a nitrogen nutrient source, the indicators of bacterial culture and bacterial production rate could not meet the requirements, and the impurities in peptone Many, containing pollutants and heavy metals, affecting the medical safety of the product. Therefore, choosing raw materials with no pollution and low heavy metal content has become the main factor to improve t...
