Why is Jasmine Rice Level 1 on average?
Jasmine rice (Oryza sativa, Thai Hom Mali variety) gets its distinctive floral, buttery aroma from the same naturally occurring volatile compound found in basmati and pandan leaves: 2-acetyl-1-pyrroline (2-AP). This compound is produced in the rice plant during growth and is concentrated in the grain. It is not sprayed, injected, or added during processing. In fact, processing reduces the aroma; freshly harvested jasmine rice is most fragrant, and the compound degrades over storage time. This is the opposite of what happens with most processed foods. The milling process for jasmine rice is identical to any other white rice: the inedible husk is removed, and the grain is polished to remove the bran layer. In our analysis, jasmine rice averages a Processing Score of 1.3, which is Level 1.

Frequently asked questions
Why does jasmine rice smell so good?
The floral aroma comes from 2-acetyl-1-pyrroline (2-AP), a volatile compound naturally produced in the rice grain during growth. It is the same compound found in pandan leaves and popcorn. Nothing is added during processing; the scent is genetic.
Is jasmine rice more processed than regular white rice?
No. Jasmine rice undergoes identical processing to any white rice: husking and polishing. The aroma is natural, not from any additional processing step. Both are single-ingredient foods.
Does jasmine rice lose its smell over time?
Yes. The aromatic compound 2-AP is volatile and degrades during storage. Freshly harvested jasmine rice is most fragrant. This is actually evidence that the aroma is natural; a manufactured fragrance would be more stable.
