Effect of alkalis on deacetylation of konjac glucomannan in mechano-chemical treatment

This paper presents experimental results on the effect of alkalis such as NaOH, KOH and Ca(OH)2 on deacetylation of a konjac glucomannan (KGM) powder under mechano-chemical (MC) treatment. The results show that the alkalinity of modifiers is a dominant factor for deacetylation of KGM. In addition, characteristics, such as swelling property, viscous stability and thermal behavior of the deacetylated KGM are analyzed.
