Method for using sea cucumber to process waste liquid for extracting sea cucumber polysaccharide

Abstract

The invention provides a method for using sea cucumber to process waste liquid for extracting sea cucumber polysaccharide. The method comprises the following steps: using a filtering apparatus for filtering waste liquid, filtering the solid impurity in the waste liquid, performing ultramicro filtering, selecting an ultramicro filter membrane with interception molecular weight being 20000-80000, performing ultramicro filtering on the collected sea cucumber waste liquid, and adding distilled water or purified water. The method uses the technologies of molecule ultramicro filtering, alcohol precipitation, resin column adsorption, and spray drying; the sea cucumber polysaccharide having health care efficacy of adjusting immune, and preventing cancer and resisting cancer can be separated and extracted from the sea cucumber waste liquid, raw material cost is greatly reduced, sea cucumber processing waste liquid discharge is reduced, and environment pollution is reduced. The method has the advantages that the utilization equipment is common, the operation is simple, the production period is short, the waste liquid is processed, the waste liquid discharge is avoided, environment pollution due to waste liquid can be avoided, and the method has effect for protecting environment.

Description

technical field [0001] The invention relates to the field of sea cucumber processing, in particular to a method for extracting sea cucumber polysaccharides from sea cucumber processing waste liquid. Background technique [0002] Sea cucumber belongs to the class of sea cucumber. Sea cucumber is not only a precious food, but also a valuable medicinal material. According to the records in "Compendium of Materia Medica": Sea cucumbers are sweet and salty, tonify the kidneys, benefit the essence, take urine, aphrodisiac and treat impotence. Modern research shows that sea cucumber has the functions of improving memory, delaying gonad aging, preventing arteriosclerosis, diabetes and anti-tumor. [0003] When working with sea cucumbers, fresh sea cucumbers are usually cut open first to remove the water and internal organs in the abdomen, and then boiled with water to further dehydrate the body wall for subsequent processing and drying. During this process, a large amount of waste...

Problems solved by technology

During this process, a large amount of waste liquid from cooking sea cucumbers will be produced. At present, this part of waste liquid has not been effectively used. Processing enterprises use it together with the brine of different concentrations used in subsequent processing as processing wastewater and discharge it directly; and these discharged Wastewater is rich in protein, carbohydrates, inorganic salts and other nutrients, which seriously pollute the environment after discharge
