Chitosan is in powder state, tasteless and odorless, and the aqueous solution is somewhat pungent. Chitosan was added to food, and the structure was not changed after boiling, frying, and baking to a certain extent. Under the protection of nitrogen, it will not decompose when heated to 250°C. The chitosan powder was stored for 181 d in a natural environment away from Chemicalbook sunlight at room temperature, and there was no obvious change in appearance, solubility, and degree of deacylation. The biscuits added with chitosan were stored in an environment with a temperature of 40 °C and a relative humidity of 75% for 80 days in the packaged state, and the content of dietary fiber and chitosan in the samples did not change.
