Humic acid is a macromolecular compound of a class of complex components, according to their solubility in different solvents were divided into three groups: fulvic acid, humic acid, fulvic acid brown. Humic acid exists widely in weathered coal, lignite, peat, content of 30% to 70% in China in 70s had raised the research and application of humic substance of the boom, is mainly to solve the shortage of agricultural fertilizer production at that time. Humic acid has biological activity and special structure performance in plant growth plays a unique role. Organic acids in the coal humic acid in nature called MFA, and by our first biochemical method for the production of humic like substances known as BFA (Biotechnolosy Fulvic scicl). This conforms to the green environmental protection technology provides a bigger platform for the application and development of humic acid products. At present, humic substances have been used in agriculture, health, petroleum, building materials, environmental protection, pesticide, fertilizer and other industries. In particular to strengthen people's awareness of environmental protection, green health food is prevailing, so to solve this problem and provide these food substances, humic acid will play a unique role in this important, humic acid will have a broader market space, faster development will also promote the product and industry.
The biological activity mechanism of humic acid:
The main elements of humic acid is composed of carbon, hydrogen, oxygen, nitrogen and sulfur, is a condensation of multivalent phenolic aromatic compounds and compounds. Wide molecular weight distribution, molecular weight of tens of thousands, high molecular weight up to tens of thousands to millions. Structure is quite complex, containing phenolic hydroxyl, hydroxyl, hydroxyl, hydroxyl radical, quinone, enol sulfonic acid, amine, free radicals, quinone semiquinone radical, quinone acetoxy, methoxy and other functional groups. The composition through bonding, hydrogen bonding, chemical adsorption and physical role together. Because of these active groups are decided, hydrophilic, acidic ion exchange of humic acid, adsorption capacity, buffer, complexation and high catalytic ability. Humic acid added in the feed, various toxic and harmful substances can be effectively absorbed feed produced by the storage of toxic substances by adsorption, digestion and metabolism can also produce in the process of digestion and metabolism. Such as: amine, hydrogen sulfide and other substances, maintain normal intestinal microflora. Humic acid in feed, can also be used as drugs, has obvious therapeutic effect on intestinal ulcer and gastritis. The fulvic acid humic acid containing small molecules, adhesion in the ulcer surface, to stop bleeding quickly, there is conducive to rapid healing of tissue. Humic acid can enhance the immune function of animal, in the immune process of antigen uptake, cellular immunity and humoral immunity in each stage were promoted. The oxidation of humic acid containing quinonyl can participate in the body reaction, maintain a strong The new supersedes the old. promote cell proliferation. Humic acid can also act on the autonomic nervous system can inhibit sympathetic nerve excitement, make animal quiet, reduce consumption. Because the humic acid is an organic acid, can regulate gastrointestinal pH value, promote the secretion of digestive enzymes in young animal, the activation of a variety of enzymes activity, changes in membrane permeability, improve the feed on nutrient uptake, improve feed utilization, promote growth and development. For biochemical fulvic acid, it not only contains humic acid, nucleic acid, it also contains a certain amount of amino acid, VB, VC, inositol, polysaccharide, has strong biological activity, or animal important nutrients. In conclusion according to the clinical evidence that humic acid has anti-inflammatory, hemostatic, analgesic, convergence, adsorption, anti allergy, promote the secretion, regulate gastrointestinal function, improve immunity, enhance the disease resistant ability of the animal. At present, some feed manufacturers, farmers to cater to consumer psychology, improve the animal's growth, the pursuit of feed effect, adding a lot of antibiotics in the feed, the antibiotic residue, directly affect people's health. Humic acid as a green product, can be added to replace antibiotics in feed. Scientific research in recent years showed that humic acid as a new feed additive, its peculiar function, in culture plays a very important role, but also will promote the development of feed industry.
The development prospect of humic acid:
For aquaculture, currently in the domestic reports are rare, as natural active substances, can replace antibiotics in a certain range, used as prevention agent. The development of humic acid has a broad market prospect. Humic acid industry problems such as small scale of production, backward technology, stable quality, the enterprise technical force is weak, the development and application of research is not enough, it restricts the development of this industry. Humic acid has a peculiar effect, its mechanism is not well understood, for further study, in order to improve the application space of humic acid and wider application value.
