Chitosan Nitrate； Chitin Derivative；shrimp& crab shells materials；chitosan food grade ; chitosan powder ; off-white
Chitosan can only be dissolved in some dilute inorganic or organic acids, not directly soluble in water.
When the sample is dissolved in water, firstly check whether the solution has viscosity. If there is no viscosity, it is low-molecular chitin or low-molecular chitosan. Secondly, add a few drops of NaOH solution to the aqueous solution to produce turbidity or precipitation, which is chitosan hydrochloride. Because the hydrochloric acid in the solution is neutralized by alkali, chitosan is not soluble in neutral or alkaline water. If you add a few drops of HCl solution and it becomes cloudy, it's carboxymethyl chitosan, because carboxymethyl chitosan is actually the sodium salt of carboxymethyl chitosan, and if this solution is acidified, it's no longer sodium carboxylic acid, it's carboxylic acid, and it's insoluble in acidic water.
White or Off-white powder with odorless. Water soluble, the solution is neutral, clear and stable.
Compared to Chitosan, the electrorheological property of Chitosan Nitrate is better, and it can be used as ER material. It is applied to raw materials and intermediates, food, biological accessories,food accessories, cosmetic, and agriculture etc.
