The results showed that the best production process conditions of tuckahoe purple potato steamed sponge cake were as follows： ratio of wheat flour to tuckahoe power at 8：2, 10% purple potato starch, 25% white granulated sugar, and 1.5% yeast powder.展开更多

LF up to 40% and BF flour up to 20% level were partially replaced with corn starch and rice flour mix in the gluten free cake recipe. Cake dough properties （specific gravity and pH）, cake properties （weight, volume, symmetry and uniformity index, hardness）, crust and crumb color values were investigated. High addition levels of LF decreased the pH values of the dough. Compared to control, volume index of the cakes improved with BF at 5% addition level or LF up to 20% level. While minimum level of the LF/BF gave softer cake texture, high substitution levels of LF （30%-40%） and BF （15%-20%） had detrimental effect on softness of the samples. All addition level of the LF increased the darkness and yellowness of the cake＇s crust and crumb, whereas BF above 5% level decreased lightness and yellowness of the samples. The high levels of LF （30%-40%） and BF （15%-20%） had reducing effect all physical properties of gluten-free cake samples.展开更多
