Title:

STABILIZATION OF AROMA-PROVIDING COMPONENTS

Document Type and Number:

WIPO Patent Application WO2002076239

Kind Code:

A3

Abstract:

A process for stabilizing an aroma-providing component such as coffee aroma against loss or degradation of desirable flavor or sensory characteriestics of its aroma during storage. The aroma-providing component is associated with a stabilizing agent in an amount effective to chemically interact with undesirable compounds to form a stabilized aroma-providing component which (a) retains a significant portion of one or more of the desirable flavor or sensory characteristics of the aroma in the aroma-containing componetn during storage, or (b) reduces off flavor generation during storage of the aroma-providing component. The stabilizing agent preferably is a nucleophile that contains sulfur or nitrogen , such as sulfur dioxide, sulfites, compounds that contain or generate thiols, amines or amino acids, cystenine, gluathione or an enzyme. The stabilized aroma-providing component retains the desirable flavor and sensory characteristics of the aroma for a time period of at least six months to one year or longer.
