Mr.
Katsumi Umano, an attendee from one of out Reaction Meat Flavor classes
volunteered the information below. The flavor is a simple meat flavor reacted under typical process conditions.
As listed there are a number of different functional groups, sulfur and nitrogen
compounds. Meat flavors are composed of a number of different ingredients
that are necessary to give acceptable meat flavor character. Model systems are
helpful to understand which chemicals are generated from the Maillard reaction,
but do not represent the flavor profiles of commercial meat flavors.
