Effects of fermentable carbohydrates on the quality properties and in vitro digestibility of Yiyang rice cake

Effects of adding resistant starch (RS), inulin (IN) and xylo-oligosaccharide (XOS) on the cooking properties, texture properties, ordered structure of starch, water mobility and in vitro digestion of Yiyang rice cake were investigated. The cooking loss of rice cake was reduced to 2.8-4.6% with the addition of XOS. Addition of these fermentable carbohydrates increased the hardness, viscosity, chewiness and order of starch. As the content of carbohydrates increased, the rice cakes gradually became smoother. RS and XOS promoted the starch retrogradation and the free movement of water in the rice cakes, and increased the ordered structure formed by the association between starch chains; IN had no obvious effect on the retrogradation. Compared with the control group, digestion rate and final digestibility level of the starch digestion model in RS and XOS groups decreased, especially the total amount of available starch of XOS120 decreased to 73.8%, indicating that they had a certain inhibitory effect on starch digestion. The crystallinity formation theories for high-moisture starch gels are not applicable to rice cakes.
