Abstract
Sustained flavor release compositions are disclosed which comprise polymer backbones having pendant flavor groups thereon. Such compositions can be used, for example, in chewing gums. Release of the flavor can be accomplished by hydrolysis upon mastication of the chewing gum. In one embodiment, aldehyde flavors are reacted with polymers having hydroxy groups thereon to produce a polymer backbone with pendant acetal or hemi-acetal flavor groups. An example is the reaction product of cinnamic aldehyde and partially hydrolyzed polyvinyl acetate. In a like manner, ketone flavors can be reacted with similar polymers to form pendant ketal flavor groups. Also, alcohol flavors can be reacted with polymers having aldehyde or ketone groups to provide polymer backbones with pendant acetal or ketal moieties thereon.
Claims3
Controlled flavor release compositions comprising a polymer backbone having a pendant flavor moiety thereon, said pendant flavor moiety being releasable from said polymer by hydrolysis and consisting of an acetal, hemiacetal or ketal flavor moiety formed by chemically reacting an alcohol flavor with a polymer having pendent aldehyde or keytone groups, said polymer having a molecular weight of from about 2,000 to about 20,000.
