The aim of this study was studying the effect acidic hydrolysis conditions on molecular parameters galactomannan, such as weight average degree polymerization (DPw), (Mw), product yield, depolymerization reaction rate, and mannose/galactose (Man/Gal) ratio in presence hydrochloric acid obtaining low oligogalactomannans soluble water. A preparing possibility galactomannans by guar galactomannan ...
