Has antibacterial, bactericidal and deodorant effects, has good decomposition and removal effects on ammonia, hydrogen sulfide and other malodors, is a substance with strong adsorbability, and mainly comprises porous ore powder such as fine zeolite powder, attapulgite powder, coal ash and the like. The deodorant has the function of preventing the odor of the excrement of the livestock and the poultry from polluting the environment, and can be added into the feed, and the deodorant mainly comprises the following types: physical deodorant, chemical deodorant, microbial deodorant, plant deodorant, composite deodorant, etc.
Deodorants disclosed in the prior art, such as a composite deodorant disclosed in patent No. 201710945570.1, are prepared by adding cedar wood extract and tea polyphenol extract to eliminate rancid odor; further, the deodorant such as patent No. 201680081436.5 is made by adding an amphoteric surfactant to zinc oxide and an amino acid as a deodorizing component and water as a solvent, and contributes to good appearance of the solution, low toxicity of the surfactant and good deodorizing ability.
The organic acid salt or the organic acid chelate of zinc and the tea polyphenol have certain deodorization function, but the method does not simply superpose the organic acid salt or the organic acid chelate of zinc and the tea polyphenol: because the zinc salt has low solubility in water and poor transparency of the water solution, after the tea polyphenol is added into the solution, the pH value of the zinc salt solution is slightly reduced, and meanwhile, polyhydroxy in the tea polyphenol can further form hydrogen bonds with zinc ions, so that the transparency and the stability of the zinc salt are improved.
