Title (EN) ORGANOLEPTIC COMPOSITIONS
(FR) COMPOSITIONS ORGANOLEPTIQUES
Abstract:
(EN) The present invention provides organoleptic compositions which upon thermolysis, hydrolysis or both, release an odorant molecule. They find utility, for example, in tobacco, in tobacco paper, and as additives to food, beverages or gum. The compositions contain one or more dicarboalkoxy dioxolane derivatives having formula (I), wherein R1 and R2 are, independently, -CO2R3 wherein R3 is -H or lower alkyl, provided that in at least one of R1 and R2, R3 is lower alkyl; wherein Z is a direct bond, or -CH=C(R4)-; where R4 is -H or an alkyl group; and Y is (II) or (III), where R5 and R6 are independently -H, lower alkyl or -OR7 where R7 is -H or lower alkyl.
(FR) Compositions organoleptiques aptes à libérer une molécule odorante lors de la thermolyse et/ou de l'hydrolyse. Elles peuvent s'appliquer, par exemple, au tabac, au papier à cigarettes, et aux additifs pour les produits alimentaires, les boissons ou le chewing-gum. Les compositions comprennent un ou plusieurs dérivés de dicarboalcoxy dioxolane répondant à la formule (I), dans laquelle R1 et R2 représentent, indépendamment l'un de l'autre, -CO2R3 où R3 représente -H ou alkyle inférieur, à condition que, dans R1 et/ou R2, R3 représente alkyle inférieur; Z représente une liaison directe ou -CH=C(R4)-; où R4 représente -H ou un groupe alkyle; et Y représente (II) ou (III), dans lesquelles R5 et R6 représentent, indépendamment l'un de l'autre, -H, alkyle inférieur ou bien -OR7 où R7 représente -H ou alkyle inférieur.
