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.

L'invention concerne des composants aromatisants stabilisés, tels que des arômes de chocolat, de thé ou de café, stabilisés contre la perte ou la dégradation d'une caractéristique aromatique ou sensorielle souhaitée de l'arôme lors de son stockage. L'agent stabilisant est présent dans le composant aromatisant en quantité suffisante pour entraîner une interaction chimique avec les composés du composant aromatisant et (a) fournir des doses importantes de composés désirés donnant des caractéristiques aromatiques ou sensorielles désirées à l'arôme ou (b) réduire la dose de composés indésirables supprimant les caractéristiques aromatiques désirées ou générant des caractéristiques aromatiques ou sensorielles indésirables dans l'arôme. L'agent stabilisant est de préférence un nucléophile renfermant du soufre ou de l'azote, tel que du dioxyde de soufre, des sulfites, des composés ou des substances contenant ou générant des sulfites, des thiols, des amines ou des acides aminés, de la cystéine, du glutathion ou une enzyme. Ce composant aromatisant stabilisé permet à l'arôme de conserver ses caractéristiques aromatiques ou sensorielles désirées pendant une période allant de six mois à plus d'un année.
