Industrial Grade ; Chitosan Powder ; Tobacco Chip-paste Chitosan ; Off-white or light yellow ; non-toxic ;
Chitosan is the product of n-acetylgroup of chitin. Generally speaking, more than 55% of n-acetylgroup is removed and called chitosan, or 1% of deacetylated chitin can be dissolved in 1% acetic acid or 1% hydrochloric acid. This deacetylated chitin is called chitosan. In fact, chitin with a degree of N-deacetylation of 55 percent or more dissolves in this dilute acid. As an industrial product, the degree of N-deacetylation of chitosan is over 70%. The n-deacetylated chitosan with a degree of 55%~70% was low deacetylated chitosan, 70%~85% was medium deacetylated chitosan, 85%~95% was high deacetylated chitosan, and 95%~100% was super deacetylated chitosan. Chitosan with 100% Degree of N-deacetylation is extremely difficult to prepare. Chitin may or may not have n-acetyl groups on each sugar group, and anything with less than 50 percent N-acetyl is called chitin because it certainly does not dissolve in dilute acids at that concentration.
This product is non-toxic,odorless,off-white or light yellow powder,and soluble in acid,insoluble in water and base or normal organic solutions.Dissolved in 185℃.
