PRODUCT INTRODUCTION
description
Ethylpyrazine is a member of the class of pyrazines that is pyrazine in which one of the hydrogens is replaced by an ethyl group. Found particularly in cereals and cereal products, it is present in baked or fried potato, bread, roasted peanuts, and cooked shrimp, as well as cocoa, coffee, and tea. It has a musty, nutty, buttery, peanut odor and a chocolate-peanut taste. It has a role as a fragrance, a flavouring agent and a Maillard reaction product.
