Jasmine rice (Thai: ข้าวหอมมะลิ; RTGS: Khao Hom Mali; Thai pronunciation: [kʰâːw hɔ̌ːm malíʔ]), sometimes known as Thai fragrant rice, is a long-grain variety of rice that has a nutty aroma and a subtle pandan-like (Pandanus amaryllifolius-leaves) flavor caused by 2-Acetyl-1-pyrroline. Jasmine rice is originally from Thailand. It was named as Kao Dok Mali 105 variety (KDML105) by Sunthorn Seehanern, an official of the Ministry of Agriculture in the Chachoengsao Province of Thailand in 1954. The grains will cling when cooked, though it is less sticky than other rices as it has less amylopectin. It is also known as Thai Hom Mali. To harvest jasmine rice, the long stalks are cut and threshed. The rice can then be left in a hulled form and sold as brown rice or shucked and sold as white rice. Most Southeast Asians prefer the white variety of jasmine rice.
Particular varieties of US-grown rice have been found to contain higher levels of arsenic due to the historical use of arsenic based pesticides in some parts of the country. Rice from Thailand and India contains the least arsenic among rice varieties.
Cambodian and Thai jasmine rice share the same characteristics and grow mainly in neighbouring geographic areas on opposite sides of the Northeastern Thai-Cambodian border. Cambodian jasmine rice (in Khmer: Phka Malis) is cultivated in Cambodia and processed as white (milled and polished) and brown rice. Distinct Cambodian jasmine rice varieties include these major three, namely Phka Rumduol, Phka Romeat and Phka Rumdeng. Recent DNA finger print analysis, carried out with 18 markers show that all three varietals possess 18 known fragrance allele. Two varietals (Phka Rumduol and Phka Rumdeng) are distinct Cambodian with 17 markers in identical position with Thai jasmine rice and one fragrance marker each in a different position. The analysis of Cambodian Phka Romeat shows all 18 markers in identical positions with the trademarked Thai jasmine rice Thai Hom Mali
