Technique for desalting fucoidin extracted from kelps by membrane filtration

Abstract

The invention discloses a technique for desalting fucoidin extracted from kelps by membrane filtration. The technique includes steps: after soaking in clear water, manually brushing fresh black and white truffles with hard-bristle toothbrushes until surfaces of the truffles are clean and water for washing the truffles is clear, manually checking whether the truffles are cleaned or not, placing thecleaned fresh truffles one by one in a ventilation platform without overlaying, putting the platform full of the truffles at a ventilation place, blowing the truffle platform for 15-30 days by oscillating industrial fans or blast blowers in a low-speed rotary blowing manner until the truffles are shrunk evidently, and knocking a wood board and the like with intact truffles to select qualified truffles which make clear and loud sound. By the technique for desalting fucoidin extracted from kelps by membrane filtration, the defect that the fresh truffles are short in fresh keeping time and highin aroma loss is overcome, and dried truffle products suitable for eating habits of Chinese can be provided.

Description

technical field [0001] The invention relates to the technical field of food and health food, in particular to desalting fucoidan extracted from kelp by using membrane filtration technology. Background technique [0002] my country is a big country in seaweed production and consumption, with rich algae resources, especially brown algae resources, among which kelp is the most common. Kelp is rich in fucoidan, which has biological activities such as anticoagulant, antitumor, antithrombotic, and antiviral. [0003] The salina polysaccharides sold in the market today are all obtained by washing the kelp extract with water and alkali, but after the water and alkali washing are completed, they cannot desalt the fucoidan well, making The polysaccharide content inside the algal polysaccharide is low, which makes the product quality of the whole salina polysaccharide low. Therefore, we propose a method for conveniently solving the above problems to extract oyster polysaccharide from ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide the use of membrane filtration technology to desalinate the fucoidan extracted from kelp, so as to solve the problem that the salt content of the salina in the existing market is relatively high, so that the whole salina Problems of lower quality and not suitable for mass production in factories
