Stabilized aroma-providing components such as chocolate, tea or coffee
aromas that are stabilized against loss or degradation of desirable flavor or sensory
characteristics of its aroma during storage. The stabilizing agent is present with
the aroma-providing component in an amount effective to chemically interact with
compounds in the aroma-providing component to (a) provide increased amounts of
desirable compounds that impart desirable flavor or sensory characteristics to
the aroma or (b) reduce the amount of undesirable compounds that suppress desirable
flavor characteristics or that contribute to or generate undesirable flavor or
sensory characteristics in the aroma. The stabilizing agent preferably is a nucleophile
that contains sulfur or nitrogen, such as sulfur dioxide, sulfites, compounds or
substances that contain or generate sulfites, thiols, amines or amino acids, cysteine,
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.
