Study on Aqueous Viscosity Behaviors of Hydroxypropyl Methylcellulose Hydrosol and Konjac Glucomanan Hydrosol

Abstract:

In this work, the viscosity behavior of hydroxypropyl methylcellulose (HPMC) and konjac glucomanan (KGM) hydrosol was studied. Effects of mass fractions, water quality and sodium chloride (NaCl) on the viscosity of hydrosol were investigated by rotating viscometer. The results indicated that the viscosity of KGM and HPMC apparently increased with the increasing of mass fraction. HPMC could always maintain high viscosity in various kinds of water, whereas the viscosity of KGM reduced in tap water. The salt resistance experiments shown that the viscosities of the two kinds of hydrosol with 0.9% NaCl appeared a little decrease, hence, all hydrosols have a good salt resistance.
