Applications in food industry:

Antibacterial agent

Chitosan and its derivatives have good antibacterial activity, which can inhibit the growth of some fungi, bacteria, and viruses.

Fruit and vegetable preservatives

Using chitosan as coating of fruits and vegetables mainly is to maintain normal quality and taste, the nutrition composition and appearance and improve its commodity value from after picking to shelf.

Due to containing high level of unsaturated lipid compounds which are susceptible to oxidation and make the meat rotten, it is easier to shorten the storage life of meat and meat flavor.

Additives for health-care food

Chitosan is difficult for gastrointestinal digestion and absorption by human body, when ingested, they can generate complex with triglycerides and fatty acid, cholesterol and bile acid lipid compounds as much as many times of its own quality, and the complex can’t be hydrolized by gastric acid or absorbed by digestive system, thereby hampering the body to absorb this kind of material and letting the complex be out of the body.

Clarifying agent for fruit juice

Juice contains a large number of negatively charged pectin, cellulose, tannins and pentose polymer material, which can make juice cloudy during storage.When the positive charge of chitosan meets with the negative charge as described above, they become flocculation. After treatment, the clean juice turns into a stable thermodynamic system allowing long-term storage without producing cloudy.
