This study was carried out to investigate milling's effect on the pasting properties and storage stability of dry-milled rice flour. Rice flour's moisture content was increased from 9.48% to 9.80% after going through a rice polisher, and the crude fat content of rice flour was decreased from 0.91% to 0.62% after going through a rice polisher. In the color index of rice flour, the rice polisher was only affected by yellowness. The pasting properties were verified through RVA, and it was confirmed that the use of a rice polisher had no significant effect on the pasting properties. As a result of observing the changes in fatty acid value, it was ascertained that the storage period could be increased using the rice polisher. These results suggest that the rice polisher can increase the storage period without changing the pasting properties.

In this study, the effects of different varieties and particle sizes of dry milled rice flour on Jeolpyeon quality were investigated. Classify particle size of dry milled rice flour according to rice variety into 50, 100, and 150 μm. A particle size of 50 μm in the varieties Boramchan and Hanareum resulted in the highest damaged starch contents (p<0.05). Additionally, the Boramchan and Hanareum varieties had the highest water absorption index (WAI) values (p<0.05). Analysis of the gelatinization characteristics of dry milled rice flour according to varieties revealed the peak viscosity of Dasan and Hanareum was high (p<0.05), regardless of particle size, while the breakdown was highest for Hanareum at all particle sizes (p<0.05). The moisture content of Jeolpyeon made with Boramchan varied between 48.83 and 53.64% among particle sizes, with no significant differences relative to the control. The hardness of the control was 3.15 kg, while the hardness of Jeolpyeon made with Boramchan decreased significantly 2.60-2.63 kg (p<0.05).

In this study, dry-milled rice flour from different varieties (Samgwang, Boranchan, Hanareum, Dasan, Hangaru) and different particle sizes were used to manufacture Jeung-pyun and the quality characteristics were analyzed. The Jeung-pyun produced from Samgwang, Dasan and Hangaru milled rice flour showed highly dense pores. The Jeung-pyun produced from Hanareum only showed a significant difference according to the particle size. Samgwang, Boranchan and Dasan varieties with a particle size of 150 m showed a significant decrease in volume (p<0.05). Samgwang showed the lowest pH at all particle sizes (p<0.05). The sweetness of Samgwang varieties was the highest at 3.27-3.63°Brix (p<0.05). The hardness of Jeung-pyun increased with increasing particle size (p<0.05). The highest acceptance of Jeung-pyun in terms of volume and bitter taste was observed with Hanareum at a particle size of 50 m. When the particle size was 50 m, the overall acceptance was highest for Jeung-pyun made from Samgwang followed by Hanareum. The acceptance of all the sensory characteristics was high when the particle size of rice flour was 50 m. When the appearance of Jeung-pyun was measured, Samgwang showed a dense structure and low hardness. Hanareum showed an increasing volume and springiness. Overall Samgwang and Hanareum were found to be the most suitable varieties for the production of Jeungpyun.
