Abstract

The invention provides a preparation method of algae extract. The preparation method comprises the following steps: impurity removal and cleaning, mincing, homogenization, pH regulation, pressurization and alkaline hydrolysis, fermentation and degradation of compound microbial enzyme and filtration, wherein a filtrate product is algae extracting liquid, and filter residue can be directly compounded into a soil conditioning agent or is dried and prepared into a algae-extract dry-powder product. The active algae extract prepared by the invention has the beneficial effects that the components such as minerals, alginic acid, algae polyphenol, mannitol and beneficial element are retained, protein and polysaccharide components in algae are degraded, and the absorption is easy; beneficial microbes and various enzymes are added, and various microbial secondary metabolites can be generated, so that the biological activity is better.

Description

technical field [0001] The invention relates to the technical field of plant extracts, in particular to a preparation method of seaweed extracts. Background technique [0002] Seaweed refers to lower plants that contain chlorophyll or other auxiliary pigments that grow in the ocean. According to the different pigments they contain, they are divided into brown algae, red algae, green algae, blue algae, yellow algae, and whole algae. Due to the characteristics of high salinity, high pressure, low temperature, and little light in the marine environment where seaweed grows, seaweed has accumulated many natural active functional substances during the growth process in response to these environmental stresses. Therefore, seaweed extract contains seaweed, alginic acid, Seaweed polysaccharides, trace elements and other effective active ingredients can be used in many aspects such as food, fertilizer, feed, medicine and industrial raw materials. Seaweed extract has been regarded as...
