Product Introduction


Chitosan and its derivatives have good antibacterial activity.


Papineau et al. believed that due to the interaction between the positive charge of chitosan molecule and the negative charge on the bacterial cell membrane, the protease and other components in the cell would leak, thus realizing the antibacterial and bactericidal effects. They found that the dosage of chitosan lactate was 0.2mg/ml, which had a good inhibitory effect on e. coli, and chitosan glutamate also had a good inhibitory effect on the reproduction of yeast such as s. cerevisiae, and 1mg/ml chitosan lactate would completely inactivate the yeast within 17min. Sudharshan et al. pointed out that chitosan could infiltrate into the core of bacteria and bind to DNA, inhibiting the synthesis of mRNA and protein, thus preventing the synthesis of mRNA and protein and achieving antibacterial effect. They studied the effects of water-soluble chitosans such as chitosan lactate, chitosan glutamic acid and chitosan hydrogenated glutamic acid on the proliferation of different bacteria. The results showed that chitosan lactate and chitosan glutamate had good antibacterial effects on both gram-positive and gram-negative bacteria. Chen et al. [2] studied the antiseptic effects of chitosan with a deacetylation degree of 69%, a sulfonated degree of 0.63%, a sulfonated degree of 13.03%, and a thiobenzoyl chitosan on oysters.




Off-white or yellowish powder with odorless, innocuous. Water soluble, the solution is neutral, clear and stable.




Chitosan lactate with a better biocompatibility has excellent functions of antibacterial activity, moisture retention, prevent disease, keep healthy and other special purposes etc. It is widely used in the fields like dressing, hygienic materials, biochemistry, health foods, functional food, food additives, intermediates and so on. Chitosan lactate is made from natural raw material, without touching the other chemical raw material in the production process, therefore it is more natural and safe.
