Cyclic ethers of formula ##STR1## wherein the dotted line indicates the location of a single or double bond and the symbol R represents an isopropenyl radical or a 1-ethoxy-1-methylethyl radical, are novel compounds with useful organoleptic properties. They can be used as active ingredients in perfuming compositions and perfumed products to which they confer rosy-fruity type odor notes. In addition, they possess flavor qualities which render these compounds useful for flavoring foodstuffs and drinks and, namely, mango-type drinks. A process for the preparation of the compounds of formula (I) is also disclosed.

Cyclic ethers and their utilization as perfuming or flavoring ingredients

Furanic esters of formula ##STR1## wherein R designates a linear or branched, saturated or unsaturated C.sub.2 -C.sub.6 alkyl radical, are novel compounds having useful organoleptic properties and, consequently, can be used advantageously in the manufacture of flavor compositions, and in the aromatization of foodstuffs, beverages, pharmaceutical preparations and tobacco products.

Furanic esters and their utilization as flavor ingredients

Use of certain .alpha.,.beta.-unsaturated aldehydes as flavoring and taste-modifying agents in the aromatization of foodstuffs in general and imitation flavors for foodstuffs, beverages, animal feeds, pharmaceutical preparations and tobacco products. Some of the disclosed aldehydes are new chemical entities.

.alpha.,.beta.-Unsaturated aldehydes and use of same as flavoring

Use of certain .alpha.,.beta.-unsaturated adlehydes as flavoring and taste-modifying agents in the aromatization of foodstuffs in general and imitation flavors for foodstuffs, beverages, animal feeds, pharmaceutical preparations and tobacco products. Some of the disclosed aldehydes are new chemical entities.
