  • Patent number: 5371069
    Abstract: The present invention provides organoleptic compositions which upon thermolyis, 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 the following formula: ##STR1## wherein R.sup.1 and R.sup.2 are, independently, --CO.sub.2 R.sup.3 wherein R.sup.3 is --H.sub.3 or lower alkyl, provided that in at least one of R.sup.1 and R.sup.2, R.sup.3 is lower alkyl; wherein Z is a direct bond, or --CH.dbd.C(R.sup.4)--; where R.sup.4 is --H or alkyl group; and Y is ##STR2## where R.sup.5 and R.sup.6 are independently --H, lower alkyl or --OR.sup.7 where R.sup.7 is --H or lower alkyl.

  • Patent number: 5147463
    Abstract: This invention provides novel cyclic acetals useful as delayed release flavorants and odorants having the general formula: ##STR1## These compounds possess no detectable flavor or odor themselves at normal temperatures and atmospheric conditions but release an aldehyde flavorant upon heating at higher temperatures. The novel cyclic acetals of the present invention may be used as flavorants in tobacco compositions or tobacco substitutes, as sustained flavorants and odorants to mask or enhance the flavors and odors of burning tobacco products, as flavor additives to microwaveable foods, and in the preparation of chewing gums.
