In this study the effect of resistant starch (RS) addition on gluten-free cakes from rice flour and tapioca starch
physical and sensorial properties was investigated. Increase in RS concentration made cake batters less elastic (drop of
G’(ω), G’’(ω) values) and thinner (viscosity decreased). Cakes specific volume increased with an increase in RS level
and was maximized for 15 g/100 g RS, although porosity values were significantly unaffected by RS content. Crumb
grain analysis exhibited a decrease in surface porosity, number of pores and an increase in average pore diameter as RS
concentration increased. During storage, cake crumb remained softer in formulations with increasing amounts of RS.
Sensory evaluation of cakes demonstrated the acceptance of all formulations, with cake containing 20 g/100 g RS mostly
preferred. Gluten-free cakes with improved quality characteristics and high nutritional value can be manufactured by the incorporation of RS.
