Chitosan Fruit Preservative Dosage

Chitosan Fruit Preservative Dosage

Experiments have shown that the chitosan solution with a concentration of 0.1% to 1% soaks cotton tissue cells, with chitosan

The increase in concentration and degree of deacetylation enhances its antibacterial effect. A 1% concentration of chitosan solution can inhibit the growth of 90% of pathogenic bacteria, and a 0.02% concentration of chitosan solution can also inhibit the proliferation of Escherichia coli. Therefore, as a preservative, the concentration of chitosan can be selected from 0.5% to 1%.

Another example is to use a solution with a carboxymethyl chitosan concentration of 0.7% to 2% and spray it on the surface of apples, pears, peaches, strawberries and other fruits to achieve the purpose of keeping fresh.
