Method for manufacturing selenium-rich fucoidin

Abstract

The invention discloses a method for manufacturing selenium-rich fucoidin, which comprises the steps: food grade fucoidin solution made by edible seaweed is processed by selenizing agent under the acidic condition, and then is hyperfiltrated and separated to remove inorganic selenium, so that the selenium-rich fucoidin is manufactured. Selenium-rich fucoidin is manufactured by the method so that selenium content can be effectively controlled, and the selenium-rich fucoidin does not contain the inorganic selenium, thus avoiding the harm brought by the inorganic selenium.

Description

technical field [0001] The invention discloses a method for producing selenium-enriched fucoidan. Background technique [0002] The necessity and toxicity of selenium are well known, but the toxicity of inorganic selenium is relatively high, and the dosage of its toxicity and physiological activity is roughly equivalent, thus greatly limiting its application. The toxicity of organic selenium is relatively low. Some data show that the toxicity of inorganic selenium is 2.94 times that of organic selenium. Therefore, many people are currently developing various organic selenium compounds through various methods, such as biotransformation and chemical addition. Various selenium-enriched products, such as selenium-enriched yeast, selenium-enriched tea, selenized carrageenan and other products. But selenium supplementation should have strict dose limitation, even its content of organic selenides is not the more the better, and the selenium-enriched sulfate fucoidan produced by th...

Problems solved by technology

[0003] The organic selenium products prepared in the current literature, whether they are organic products directly ethanol-precipitated after biotransformation or selenization, inevitably contain a certain amount of inorganic selenium, so there are certain hidden dangers in safety
