Jasmine rice (Khao Dawk Mali 105) was obtained from a producer
in Surin province located in the eastern part of Thailand.
The sample was put in a laminated aluminium bag, purged with
nitrogen, then vacuum sealed and kept at 4 C until analysed.
Basmati (Indian fragrance rice) and Jasmati (RiceSelect™, American
grown Jasmine-style long grain rice) were obtained from a supermarket
in the United States and were packed in a glass bottle with
a screw-top lid, purged with nitrogen and kept at 4 C until analysed.
In an effort to cook the rice samples in the form they would
normally be prepared for consumption, 5 g of rice and 5 g of distilled
water was added into a 40-mL glass vial, the headspace
purged with nitrogen gas and loosely sealed with a Teflon-coated
septum screw cap and placed into the bottom of a rice cooker
(Black & Decker, Model No. RC3406) at 100 C, for 18 min.
