A study of the viscosity of water solutions of inulin – the functional food ingredient

Abstract

Inulin is a perspective ingredient for the production of dietary, functional low fat and low sugar foods with improved structure, stability and taste sensations. To ensure product’s balanced nutritional profile and excellent taste properties, it is necessary to carry out a thorough study of physicochemical properties of the ingredients, especially their viscosity. The viscosity of diluted water solutions of inulin, extracted from tubers of Jerusalem artichoke, were examined. Kinematic, relative and specific viscosity was measured by a usual method using viscosimeter.
