What is kojic acid powder?
The main ingredient of kojic acid powder bulk is kojic acid, which is an organic acid with an antibacterial effect produced by aerobic fermentation of microorganisms. It is a weakly acidic compound with a molecular structure similar to glucose. It is formed by oxidative dehydration, and its acidity is derived from its phenolic hydrocarbon structure.
How is Kojic Acid obtained?
Kojic acid powder bulk on the cultivation method,and the static culture method is used in the early stage, but because the acid production process of Aspergillus is aerobic metabolism, static culture only produces acid on the surface, so the yield is not high. To make the Aspergillus vigorous in the fermentation process, Wan et al. developed a new type of fermentation tank that can maintain cell viability, which can be used in the production of kojic acid to relieve the fatigue of Aspergillus during repeated fermentation. When the utilization rate reaches 75%, cultivate 11. It can still reach 5 after 5 days. The yield of 39 g /( L·d). Okayama University in Japan has researched the production of kojic acid by membrane-surface liquid culture (MSLC) and achieved good results. The yield of kojic acid is as high as 14. 29 g /( L·d). Common cultivation methods and production efficiency are as follows: Surface static cultivation method, production efficiency 0. 75 ~ 1. 00 g /( L·d); Membrane-liquid interface culture method, production efficiency 14. 2 g /( L·d); Semi-continuous crystallization separation method, production efficiency 7. 2 g /( L·d); Immobilized growth cell method, production efficiency 3.7 g /(L·d).
How to use kojic acid powder?
In the field of cosmetics, kojic acid at a concentration of 20ug/ml can inhibit 70-80% of the activity of a variety of tyrosinase (or polyphenol oxidase PPO), and the general addition amount in cosmetics is 0.5-2.0%.
Food processing field. Kojic acid can be used as a food additive to play a role in preservation, anti-corrosion, and anti-oxidation.
The medical field. Kojic acid has been used as the raw material of cephalosporin antibiotics, and the finished drugs produced are used to treat headaches, toothaches, and local inflammations. The analgesic and anti-inflammatory effects are very ideal.
Agriculture field. Add 0.5-1.0% kojic acid to make micro-fertilizer (dark red liquid). This kind of crop production promoter has an obvious effect on increasing the production of grains and vegetables.
