2-acetyl-1-pyrroline in the context of Homolog (chemistry)

Aromatic rice is one of the major types of rice. It is a medium- to long-grained rice. It is known for its nutty aroma and taste, which is caused by the chemical compound 2-acetyl-1-pyrroline. Varieties of aromatic rice include Ambemohar, Basmati, Jasmine, Radhunipagal, Sona Masuri, Texmati, Tulaipanji, Tulshimala, Wehani, Kalijira, Chinigura, Gobindobhog, Kali Mooch and wild Pecan rice. When cooked, the grains have a light and fluffy texture except for Gobindobhog rice which is sticky in texture.

Aromatic rice produces more 2-acetyl-1-pyrroline than usual due to a loss-of-function mutation in the BADH2 gene. The BADH2 mutation can be transferred by conventional breeding; it is a recessive trait. Gene editing can be used to induce a similar mutation in ordinary rice, turning them aromatic without affecting other traits.

Jasmine rice (Thai: ข้าวหอมมะลิ; RTGS: Khao hom mali; Thai pronunciation: [kʰâːw hɔ̌ːm malíʔ]) is a long-grain variety of fragrant rice (also known as aromatic rice). Its fragrance, reminiscent of pandan (Pandanus amaryllifolius) and popcorn, results from the rice plant's natural production of aroma compounds, of which 2-acetyl-1-pyrroline is the most salient. A rapid loss of aromatic intensity leads many Southeast Asians and connoisseurs to prefer each year's freshly harvested "new crop" of jasmine rice. Jasmine rice is a variety of Oryza sativa.

Jasmine rice is grown primarily in Thailand (Thai hom mali or Thai fragrant rice), Cambodia (phka rumduol or Cambodian jasmine rice), Laos, and southern Vietnam. It is moist and soft in texture when cooked, with a slightly sweet flavor. The grains cling and are somewhat sticky when cooked, though less sticky than glutinous rice (Oryza sativa var. glutinosa), as it has less amylopectin. It is about three times stickier than American long-grain rice.
