Abstract

To increase rice consumption and substitute rice flour for wheat flour to make gluten-free bakery products, the physicochemical and pasting properties of rice flours prepared from raw and soaked rices passed through different size screens were investigated. The quality properties of manju dough and preparation of rice manju were also measured. Dry milled flour with soaked rice (DMFSR) were decreased in ash and crude lipid contents compared to dry milled flour with raw rice (DMFRR). Water binding capacity, damaged starch content, and L value of rice flour increased with decreasing particle size, but the b value decreased. Peak, cold, and breakdown viscosities of DMFSR were higher than those of DMFRR by RVA. Hardness of manju dough with DMFSR was lower than that with DMFRR, but that of manju shell exhibited a reverse trend. Sensory difference testing revealed the smoothness of surface, hardness, roughness, and overall quality were significantly different (p<0.05). The smoothness of the surface of manju with DMFRR-200 and all DMFSR were better than that of manju prepared with wheat flour. Hardness showed lower values in DMFRR-200, and all DMFSR as well as wheat flour and roughness decreased with decreasing particle size. Rice manju with wheat flour, DMFRR-200, DMFSR-120, and DMFSR-170 ranked above 5 points and were not significantly different (p<0.05).
