    Abstract:
    Gluten-free breads were developed from rice flour and corn starch at a constant ratio 1:1 with acorn meal addition (5, 15, 25%), at three levels of water (65, 70, 75%). Acorn supplemented gluten free breads better met sensory preference than rice breads in terms of colour (brown hue was enhanced) and were also nutritionally improved in terms of total phenolics. The specific volume of breads significantly decreased with increasing acorn addition while crumb hardness was also increased. SEM images confirmed that the decrease in the ΔH values at low water level (65%) was due to less swelling of starch as observed from large starch granule remnants present after baking. XRD measurements revealed coexistence of "B" and "V" type starch structures. Increasing of acorn concentration enhanced the intensity of FTIR bands at 994, 1016 and 1077 cm-1.
