Effect of addition of native and gelatinized starches from various sources (CS, corn; WCS, waxy corn starch; WS, wheat; PS, potato starch; KB, kidney bean SP, sweet potato; and RS, rice starch) on viscoelasticity and sponge-making properties of wheat flour (WF) was investigated. Sponge cakes prepared using native and gelatinized starches were compared to those prepared with 100% WF. The addition of gelatinized starches from various botanical sources led to increase in batter viscosity (increased storage and loss modulus and decreased tan δ) of batter. Sponge cakes made with addition of native and gelatinized starches from different botanical sources showed higher springiness, specific volume and cohesiveness. Firmness of sponge cakes showed variation among botanical sources and type (native or gelatinized) of starch. Sponge cakes prepared from gelatinized RS showed firmer texture. The crust color became more reddish brown on addition of gelatinized starch from all sources, however, crumb color varied with the source. Overall, it was observed that addition of gelatinized starches resulted in sponge cakes with softer texture and better organoleptic properties as compared to those made from WF.
