These researches were to determine the preparing and drying on physical and chemical properties of germinated khaohang rice from KDML105. Two factors on study were preparing germinated khaohang rice (chill at 5 oC and frozen -20 oC) and drying method (tray drier and infrared drier). The results on expansion (%) and texture of cooked rice found that there were not significant influence interaction and two main factors. But main factor on infrared drying method were affected to the highest head rice yield (%) and lowest on Chroma (C*). As same as gamma amino butyric acid (GABA) had the highest 23.37 (mg/100g) and preparing germinated khaohang rice had between 20.50 to 22.21 (mg/100g). The pasting properties reducing sugar total phenolic scavenging activity of DPPH free radical (%) and resistance starch were significant influence interaction.

The objectives of this research were to find the correlation between the milling degree and the milling quality of rice which was the basic data to investigate the milling degree equipment. Chainat 1 and KDML 105 rice varieties were milled at difference degree of milling (DOM) which calculated from bran removed. The study revealed that as the DOM increase the milled rice and head rice decreases. Therefore the whiteness transparency and milling degree of milled rice which was measured from Milling Meter also increased. When the DOM increased the whiteness transparency and milling degree also increased. The DOM had highly correlation not only to milled rice and bran but also to milling degree from Milling Meter at R2=0.99 and R2=0.97. So these correlations could be used to investigate the milling degree equipment.
