KDML 105, a well known traditional Thai jasmine rice variety, is sweet aromatic rice. Although rice aroma combines more than 200 volatile compounds, a compound named 2-acetyl-1-pyrroline (2AP) is the main constituent. The aromatic 2AP has also been found in other cereals, pandan, bread flower, fungi and bacteria.

泰国农业大学网站消息，众所周知，KDML 105是一个特异的泰国芳香水稻品种，尽管稻米的香味是由200多种不稳定的化合物形成，但其中一种叫乙酰基吡咯啉（2-acetyl-1-pyrroline）的化合物是这种香味形成的主要成分，在其他谷类、班兰、真菌和细菌中也发现了这种化合物。
