Problems solved by technology

[0006] In summary, in the existing preparation technologies of carrageenan oligosaccharides, carrageenan itself is used as the substrate, and the carrageenan molecule is degraded by enzymatic hydrolysis, which requires high substrates, and different types of enzymes can only be specifically degraded A certain type of carrageenan can obtain a specific type of carrageenan oligosaccharide (such as κ-carrageenase can only degrade κ-carrageenan to obtain κ-carrageenan oligosaccharide), which is not universal
At the same time, the existing carrageenan production process produces a large amount of waste water, most of which directly enter the reclaimed water treatment process. The cost of sewage treatment is relatively high, and it has a certain impact on the environment

Abstract

The invention provides anti-freezing carrageenan oligosaccharide and a preparation method and application thereof, belonging to the technical field of industrial waste recycling and functional oligosaccharide preparation. According to the method disclosed by the invention, the anti-freezing carrageenan oligosaccharide is extracted by fully utilizing wastewater generated in carrageenan production process through a membrane method; so carrageenan production wastewater is comprehensively developed and is turned into the valuable from the waste, sewage treatment difficulty is reduced, the production cost is effectively reduced; the method has universality for different types of carrageenan oligosaccharides; and the prepared carrageenan oligosaccharides have application value in the fields of food, health care products, cosmetics and the like.

Description

technical field [0001] The invention belongs to the technical field of industrial waste reuse and preparation of functional oligosaccharides, and in particular relates to a frost-resistant carrageenan oligosaccharide and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Carrageenan (also known as carrageenan, carrageenan) is a kind of hydrophilic colloid extracted from red algae (Rhodophyta), which is a kind of linear polymer polysaccharide containing sulfate groups. The ideal carrageenan has repeating α-(1→4)-D-galactopyranose-β-(1→3)-D-galactopyranose (or 3,6-endether-D-semi lactopyranose) disaccharide unit skeleton structure. [...
