Method for coproducing fucoidan and seaweed fertilizer

Abstract

The invention discloses a method for coproducing fucoidan and a seaweed fertilizer. The method comprises the following steps: (1) extracting a brown seaweed component having a plant growth promoting function; (2) extracting the fucoidan; (3) preparing a seaweed fertilizer component 2; and (4) blending the seaweed fertilizer, namely completely adding the seaweed fertilizer component 1 obtained in the step (1) into the seaweed fertilizer component 2 obtained in the step (3), stirring and mixing uniformly, standing for precipitating for 2 hours, filtering and centrifuging to perform liquid-solid separation, wherein the obtained liquid and solid refer to a liquid seaweed fertilizer base and a solid seaweed fertilizer base respectively. According to the method for coproducing the fucoidan and the seaweed fertilizer, resources are fully utilized, and the fucoidan product and the seaweed fertilizer are produced by means of the processes of ethanol soaking extraction, probiotics fermentation and the like, so that the problems of high water consumption as well as generation of waste water and waste residues in the production of the fucoidan are solved fundamentally, the additional value of the brown seaweed industry is increased remarkably, and a remarkable ecologic benefit is achieved.

Description

technical field

[0001] The invention relates to a method for co-producing fucoidan sulfate and seaweed fertilizer. Background technique

[0002] Fucoidan sulfate (English name: fucoidan; another name: fucoidan) is a sulfated acidic mucopolysaccharide produced by brown algae such as kelp, macroalgae, and mozuku. Because this polysaccharide has many health care functions such as anti-tumor, anti-coagulant, lowering blood fat, preventing and treating kidney disease, improving the body's immunity, and maintaining the skin, it has received more and more attention at home and abroad in recent years, and its price is far from Higher than traditional brown algae industrial products such as sodium alginate. However, no matter the technology of producing fucoidan sulfate from brown algae raw materials or the technology of extracting fucoidan sulfate from industrial waste residue of brown algae will consume a lot of fresh water and produce a lot of waste water and waste residue.
