harder and fluffier texture when cooked. Th is means that KDML 105 rice sales in Asian market have to be stored
for a certain period to allow time for the formation of it s quality. During storage howev er, aroma quality of the rice
as measured by the amount of 2-acetyl -1-pyrroline compound decreased (Widjaja et al., 1996a; Wongpornchai et
al ., 2004). Moreover, storage takes longer period of time and costly, and since rice must be supp lied continually to
market through out the year from the time of harvest. To solve this problem and to supply rice with good texture
and aroma quality, a rice processing technique using heat treatment may be employed. The objective of this study
was to determine textural properties, viscosity, and 2-acetyl-1-pyrrolin e retention of freshly harvested KDML 105
milled rice after heating with different temperatures and exposure durations.
