Abstract

The present invention provides process of utilizing kelp comprehensively and extracting fucoidin. The process has secondary soaking of kelp to raise the leaching rate of iodine, mannitol and fucoidin and to lower algin extracting cost. The water after enhanced stirring is flocculated to purify, and this can improve the iodine and mannitol extracting condition for high product yield and simplify post purification of fucoidin. The process of the present invention has improved product extracting condition, lowered production cost, obviously raised iodine, mannitol and fucoidin extracting rate and raised kelp resource utilizing value.

Description

technical field [0001] The invention relates to a method for producing fucoidan by comprehensively utilizing wastes in the process of processing and producing alginate, iodine and mannitol from kelp, which is a method for preparing fucoidan from scum separated by kelp soaking in water and alkali refining. Background technique [0002] Fucoidan, also known as fucoidan, is an inherent intercellular polysaccharide in brown algae, which exists in the cell wall matrix. Its function may be that when the tide is low, the algae are exposed to the atmosphere to absorb moisture and prevent drying. Studies have shown that fucoidan has certain anti-hyperlipidemic and tumor-inhibiting drug activities. In recent years, it has attracted the attention of pharmaceutical research and development personnel. The product can produce natural active drugs that are anti-tumor, anti-virus, and hypolipidemic. The treatment of vascular diseases and renal function diseases can also produce health prod...
