Rheological study of layer cake batters made with soybean protein isolate and different starch sources

The study of new gluten-free foods suitable for celiac people is necessary since people allergic to wheat proteins are more and more frequent This study examined the effect of using different starch sources (rice corn potato and wheat) and protein types (soy protein isolate wheat protein) at different percentages (0% 10% 20%) on the rheological properties of batters (flow viscoelastic and stickiness behaviour) and on batter density and cake volume The highest consistency viscous and elastic moduli and adhesive force corresponded to batters made of rice starch and soy protein isolate which showed the most similar Theological behaviour to wheat flour batters The batters obtained showed adequate characteristics in processing and in achieving high quality products However the percentages of starches and proteins should be experimentally optimized in each case (C) 2010 Elsevier Ltd All rights reserved
