摘要

During the batch dry-milling process, two major factors are influencing on the physical properties of milled rice flour. These two factors are rice feeding amount and milling period. Four variables were discussed, including the milling temperature, particle size distribution, solubility and damage starch content. The results reveal these two factors, rice feeding amount and milling period, were significantly leading the changes of milling temperature, solubility, and damage starch content (P＜0.001) and their cross effects were also with significant influence (P＜0.001). As these two factors increasing, the milling temperature is raising and the amount of damaged starch is also increasing. The change of solubility was followed with the differences of feeding amount. The lower feeding amount (50g) would result the increasing solubility with continuously milling. The higher feeding amount (200g) would bring the opposite situation.
