Bulk density of ordinary chitosan is about 0.2-0.4 g/ml, but the bulk density of high density chitosan is about 0.4-0.8 g/ml.Bulk density of High Density Chitosan is much higher than ordinary chitosan, and the same type of capsule can contains more weight of chitosan. For example, 0# capsule can contain 500mg of High density chitosan, but same 0# capsule can only contain 250mg ordinary density chitosan.
Structure
