Abstract
Abstract One or more five or six membered oxathio heterocyclic compounds having one sulfur atom and one oxygen atom, such as an oxathiolane or an oxathiane, is used to alter, modify or enhance the flavor or aroma of a foodstuff, chewing gum or medicinal product. Among said oxathio heterocyclic compounds are the seven novel compounds: 2,6-dimethyl-2-phenyl-1,3-oxathiane 2-isobutyl-6-methyl-1,3-oxathiane Ethyl-2,6-dimethyl-1,3-oxathiane-2-acetate 2,6-dimethyl-2-acetyl-1,3-oxathiane 2-n-nonyl-6-methyl-1,3-oxathiane 2-isobutyl-1,3-oxathiolane 7-methyl(6-oxa-10-thiaspiro) 4.5-decane
