Embodiment 1

[0020] see figure 1 A method for decolorizing sea cucumber peptide powder using membrane filtration technology, comprising the steps of:

[0021] S1. Sea cucumber pretreatment: cut 1 kg of fresh sea cucumber with scissors to remove internal organs, chop the sea cucumber skin and grind it into a slurry;

[0022] S2. Enzymolysis: add 0.4% alkaline protease, 0.5% neutral protease; 0.2% flavor enzyme by weight of solids in the extract, and enzymolyze at 50°C-55°C for 4 hours;

[0023] S3. Filtration and decolorization: use diatomaceous earth and activated carbon to decolorize the raw materials;

[0024] S4, ultrafiltration membrane filtration: Utilize ultrafiltration membrane to decolorize and filter;

[0025] S5. Concentration under reduced pressure: use a double-effect concentrator to concentrate the enzymatic solution to a solid content of 30%-40%;

[0026] S6. Spray drying: control the inlet temperature at 160°C-190°C, the outlet air temperature at 90°C-100°C, and the feed ...

Abstract

The invention belongs to the technical field of physical engineering, in particular to a method for decolorizing sea cucumber peptide powder by a membrane filtration technology. The method includes the following steps of sea cucumber pretreatment, enzymolysis, filtration, decolorization, ultrafiltration membrane filtration, decompression concentration, spray drying and the like. By enzymolysis, filtration, decolorization, ultrafiltration membrane filtration and the other steps, the maillard reaction in the production process of the sea cucumber peptide powder can be effectively reduced, some pigment molecules are intercepted, and thus the purpose of decolorizing sea cucumber peptide powder is achieved.

Description

technical field [0001] The invention belongs to the technical field of physical engineering, and in particular relates to a method for decolorizing sea cucumber peptide powder by using membrane filtration technology. Background technique [0002] Filtration is a common physical treatment used to remove insoluble substances from liquids. Adding a filter aid to the solution, or pre-coating a layer of filter aid on the surface of the filter cloth, can significantly improve this situation. The filtration speed is faster, the filtrate is clear, and the filter residue is relatively tight and can fall off from the filter cloth. The most commonly used filter aid in various industries is diatomite; in some occasions where diatomite is used for filtration, activated carbon is also added to simultaneously absorb and remove colored substances and other substances that have a negative impact on product quality . [0003] During the production of sea cucumber peptide powder, a Maillard ...
