The 2007 Ig Nobel Chemistry prize winner was Mayu Yamamoto (International Medical Centre of Japan) for developing a way to extract vanillin (vanilla fragrance and flavour) from cow dung. The 2007 Ig Nobel Prize winners were announced 5th October 2007 and prizes prizes awarded at Harvard in America. To celebrate, a local ice cream bar put on a tasting session of a new flavour, Yum-A-Moto Vanilla Twist, concocted in honour of the 2007 Ig Nobel Chemistry Prize winner Mayu Yamamoto. The mind boggles.
The 2006 Ig Nobel Chemistry prize winner was Antonio Mulet, José Javier Benedito and José Bon of the University of Valencia, Spain, and Carmen Rosselló of the University of Illes Balears, in Palma de Mallorca, Spain, for their study "Ultrasonic Velocity in Cheddar Cheese as Affected by Temperature".
