Problems solved by technology

[0002] The existing marine biological products have their own advantages and disadvantages, and cannot meet the needs of multiple functions at the same time
For example, chitin has poor solubility and can only be dissolved in organic solvents; chitosan is soluble in water, but its water retention decreases and the solution viscosity is not good; sodium alginate is soluble in water, its viscosity is good, but its gel strength is low and its water retention is poor; Carrageenan and agar gel have good strength, but are insoluble in water at room temperature
Disadvantages of the above five products: they cannot meet the requirements of easy dissolution, good water retention, high strength after gelation, strength after film formation, high solution viscosity, and variability and insoluble in water. Therefore, they are widely used in medicine, cosmetics, food and agriculture. The use is limited, resulting in high cost of use and poor use effect

Embodiment 1

[0029] A kind of marine polysaccharide of the present embodiment, its raw material comprises the following components, respectively according to the mass percentage of each component: 10% of shrimp shell, 20% of crab shell, 10% of kelp, 15% of Eucheuma, asparagus 25%, Macroalgae 20%.

[0030] The production technique of above-mentioned a kind of marine polysaccharide, comprises the following steps:

[0031] (1) Prepare raw materials: remove various impurities in the raw materials, weigh various raw materials according to the mass percentage of each component, the raw materials must not have mildew, dry the raw materials until the moisture is lower than 38%, and store them for a long time under salt immersion conditions for future use.

[0032] (2) Alkali treatment: soak the raw material with 7-12% NaOH solution at 55-65° C. for 3-4 hours.

[0033] (3) Washing lye: the raw material after alkali treatment is soaked and washed with water first, and then rinsed until the pH value...

Abstract

The invention, which relates to a marine polysaccharide and its manufacturing process, pertains to the technical field of marine biomacromolecule polymers. The raw materials formula comprises 30-70 wt% of shrimp shell or crab shell or shrimp shell and crab shell and 30-70 wt% of one or more materials selected from the group consisting of sea-tangle, Eucheuma, asparagus and kelp. The manufacturing process provided by the invention comprises the following steps of: (1) preparing clean raw materials; (2) carrying out an alkali treatment on the raw materials by using a NaOH solution; (3) washing the raw materials to remove the alkali lye; (4) processing the washed raw materials by using a mixed liquor of HCl and H2SO4; (5) washing the raw materials to remove the acid solution; (6) digesting and dissolving the raw materials by using a mixed liquor of protease and cellulase; (7) carrying out the insulation pressure filtration on the dissolved substances to produce a filtrate; (8) solidifying and maturing the filtrate by using a mixed liquor of KCl and CaCl2; (9) dehydrating the matured solid; (10) crushing the bulk solid into particles by using a pulverizer; (11) drying the particles; and (12) sterilizing the dried particles to obtain the marine polysaccharide product. The manufacturing process provided by the invention is scientific and reasonable. The marine polysaccharide product is easy to dissolve, has strong water retention, adjustable viscosity and adjustable gel strength.
