Alginic acid, chitin, humic acid, fish protein


1. Alginic acid

Alginic acid is a natural active substance that exists in algae cells by linear polymerization of monouronic acid. Seaweed fertilizer refers to the use of natural algae grown in the ocean as raw materials, through chemical, physical or biological methods to extract the active ingredients in seaweed, rich in organic nutrients and active substances that regulate plant growth. Fertilizer, applied to plants as nutrients, can promote plant growth, increase yield, and improve the quality of agricultural products. It is a new type of green and environmentally friendly fertilizer.

The general extraction process includes chemical hydrolysis (high temperature of strong alkali destroys the activity of endogenous substances in seaweed), enzymatic wall-breaking process (directed enzymatic hydrolysis, single product, large molecular weight, which is not conducive to absorption), biological fermentation (maximum retention The content of natural active ingredients in seaweed, the extraction products are rich, and the concentration of synergistic ingredients is high and active). At present, many extraction processes on the market adopt chemical hydrolysis method. Shandong Enbao Biotechnology Co., Ltd. completely abandons the chemical method of conventional strong alkali and high temperature , using the patented technology of solid-state fermentation cell wall autolysis and synergistic extraction technology, which greatly retains the rich active substances in seaweed.

2. Chitin

Also known as chitin, chitin, shell protein, crab chitin, etc., it is widely found in lower animals, especially the shells of arthropods (such as insects, spiders, crustaceans, etc.) and lower plants (such as fungi, algae, yeast, etc.) etc.) in the cell wall, is a natural biopolymer, which is a linear polysaccharide. Generally, active substances are extracted by chemical methods, and there are also technologies such as biological enzymatic treatment and physical crushing.

3. Humic acid

Humic acid is the remains of animals and plants, mainly the remains of plants, which have been decomposed and transformed by microorganisms, as well as a series of complex geochemical reaction processes and accumulated organic substances. Including coal humic acid and biochemical humic acid, coal humic acid refers to humic acid or fulvic acid and its salts extracted from coal. Generally, it can only be used for fertilizer addition after a series of chemical reactions. It is also one of the commonly used extraction technologies on the market. , the cost is relatively low. Biochemical humic acid is a humic acid-like substance produced by inoculation and fermentation with waste straw and bagasse as raw materials. In addition to humic acid, its active components include some amino acids, enzymes, trace elements, sugars and other active substances.

4. Amino Acids

It is a general term for a class of organic compounds containing amino and carboxyl groups. There are two sources of amino acids, animals and plants. Plant-derived amino acids mainly include fermented products such as soybeans and cakes, as well as scraps of soy products and vermicelli; animal-derived amino acids mainly include leather, hair, fish meal and scraps of slaughterhouses.

The main production methods are: acid hydrolysis method (low production cost, relatively simple process, using hydrochloric acid or sulfuric acid for hydrolysis treatment), fermentation method (strict requirements for fermentation strains, low product concentration, long production cycle), enzymatic hydrolysis method (cost relatively higher, amino acid species retention is more comprehensive, and activity is high).

5. Fish Protein

Fish protein is a process of pulverizing or grinding low-value fish and shrimp, and then degrading the protein into low-molecular-weight peptides and amino acids by the decomposition and digestion of its own enzymes or microorganisms. Both fish protein fertilizer products contain not only amino acid molecules, but also other active substances to play a role. The conventional chemical method of amino acids destroys the types of amino acids, and the biologically fermented fish protein is richer in active substances.
