A colorless transparent high viscosity 6-o-carboxymethyl-chitin solution and a method for producing white 6-o-carboxymethyl-chitin powder

摘要

The present invention relates to a colorless transparent high viscosity 6-O-carboxymethyl-chitin solution and a process for preparing white 6-O-carboxymethyl-chitin powder, and more particularly to a process for producing powder chitin of high purity and high molecular weight, Chitin having a degree of substitution of only 0.7 to 1.0 in the hydroxyl group of the 6-carbon of chitin.
