        The value of using rice flour processed into rice powder in preparing porridge was evaluated by measuring the moisture content, pH, total starch, reducing sugar, and color content. The moisture content of the rice flour and the pH of porridge made with rice flour were measured. Rice flour contained 77.55% moisture and the moisture content of the porridge made from rice flour processed into rice powder was 91.40 to 92.47%. The pH of rice flour porridge was acidic at 6.53 to 6.95. The color of the porridge was also measured. The L* values ranged from 82.62 to 97.55, the a* values ranged from -0.09 to 0.08, and the b* values ranged from -2.74 to 1.91.

        Although rice production gradually increased in Korea, rice consumption has been significantly reduced during the last decade. To increase rice consumption, it is necessary to develop a wide range of rice-processed foods and functional rice materials. In association with digestion in rice-functional materials, people are interested in resistant starch (RS). The purpose of this study was to develop the citrated organic rice flour by dry process with different treatments and to investigate its physicochemical properties. Citric acid (0, 20, 30, 40% dry basis) was mixed with organic rice flour and reacted at 105oC and 150oC for 5 h. The degree of substitution increased with increasing citric acid concentration and reaction temperature. In DSC, when reacted at 105oC, onset temperature gradually decreased with increasing citric acid concentration but no DSC thermal characteristics were observed when reacted at 150oC. Relative crystallinity determined by XRD did not greatly change at 105oC but dramatically decreased at 150oC. As citric acid concentration and reaction temperature increased, rapidly digestible starch, slowly digestible starch, and total starch decreased but RS significantly increased. Therefore, RS content in organic rice flour increased with dryprocessed citric acid treatment and this could be applicable to produce functional foods for diabetes.
