PRODUCT INTRODUCTION
description
2,5-Dimethyl pyrazine is held chiefly responsible for the typical flavor of Potato Chips (oil-fried, thin-sliced Potato). It has therefore been manufactured synthetically and is used in the reconditioning of commercial products, such as Potato Chips and the packaging material for same, and also for reconditioning of "instant" coffee.
