RHEOLOGICAL PROPERTIES OF THE CONCENTRATED AQUEOUS SOLUTIONS OF HYDROLYZED GALACTOMANNAN DERIVATIVES
Abstract
A process of acidic hydrolysis of natural polysaccharide of galactomannanfrom GleditsiaAquatica was studied on temperature changes and time constant. It is shown that the molecular weight of galactomannans, a ratio of galactose and mannose are decreasing with increasing of hydrolysis temperature. The processes of viscous flow of aqueous solutions of hydrolysedgalactomannan derivatives were investigated in different temperatures. It is shown that all of the studied systems were non-Newtonian fluids with pseudo-plastic type of viscous flow aperiodicities.
Structure of aqueous solutions of the hydrolyzed galactomannan samples was estimated by values of average sizes of kinetic units to compare the mobility of the structural components and their sizes for concentrated systems.
It is shown that the molecular structure of galactomannan is the main factor of determining the structure of their concentrated solutions. The size of associates is increased accordingly in increasing of the degree of hydrolysis, forming more larger but less stable associates of hydrolysedgalactomannans.
