 "The aroma-active compounds in the cooked black glutinous rice were: 2-Acetyl-1-pyrroline, (E,E)-nona-2,4-dienal, 2,3-butanediol, 1-octen-3-ol and possibly 4-vinyl-2-methoxyphenol. White glutinous rice was rich in alkanes and alkenes, but these compounds did not contribute much to the aroma characteristics of the rice.  Aroma- active compounds detected in the cooked white, glutinous rice were: (E,E)-nona-2,4-dienal, methyl dodecanoate, nonanal, ethyl octanoate, germacrene-D, two unknown compounds and tentatively butanoic acid." \\

 "The most potent odor-active compound in BA [Basmati] was hexanal (OAV 232; relative proportion = 72.6%) followed by (E)-2-nonenal (25; 7.8%), octanal (19; 5.9%), 2-AP (17; 5.3%), heptanal (12, 3.8%), and nonanal (5.1; 1.6%)... With the exception of 2-AP, aldehydes were thought not to be particularly important odorants in rice; however, we found they made up>97% of the OVAs in the rice cultivars studied, indicating a critical role in theoverall aroma. It has also been reported that hexanal, (E)-2-nonenal, and octanal contribute to off-flavors in rice that develop during storage. Changes in the concentration of these compounds may have a pronounced effect on flavor." \\
