Starches with varying amylose/amylopectin ratios and from different sources bring about different physical, textural and pasting properties during and after cooking (Champagne, 1996). According to a comprehensive review written by BeMiller (2011), many works have been done on the mixtures of hydrocolloids and starch-based flours from different sources including corn, wheat, potato, sweet potato, rice and etc. However, glutinous rice, with its unique sticky texture upon gelatinisation (due to high amylopectin content), has not been widely reported. The aim of this study was to manipulate the physicochemical properties of hydrothermally treated polysaccharide mixtures (i.e. glutinous rice flour and XG) in order to improve the textural and sensory quality of gluten-free food. XG was incorporated at different concentrations to study the effect of XG on the properties of HTT-PSM.
