A cake batter recipe containing 100% rice flour,100% sugar,25% shortening ,9%egg white powder, 3%salt and 5% baking powder (all percentages are given on a flour weight basis)was used in the experiments. The amount of water added to the batter was 27% of the overall formulation. Gums(xanthan gum ,guar gum,xanthan-guar gum,locust bean gum and k-carrageenan) were added in the formulation as1%, which was determined by preliminary experiments.Xanthan-guar gum was prepared by mixing these gums in equal proportions (0.5%each).A cake batter containing no gum was used as control.
