Flavoring ingredients

2,4,7-decatrienal as perfuming or flavoring ingredient

S,S'-ethylidene dithioacetate is used as a flavoring ingredient for giving the edible products in which it is incorporated not only a sulphurous but also a green, fruity, rich and even meaty quality. It has been particularly successfully used in grapefruit and other fruit flavorings. It can also be used in the preparation of perfuming compostions.

Use of S,S'-ethylidene dithioacetate as a perfuming and flavoring

Ethyl (2E,4Z,7Z)-2,4,7-decatrienoate, a novel compound, is a useful perfuming ingredient capable of imparting odor notes of the pear, green, violet leaf type to the compositions and articles into which it is incorporated. It can also be advantageously used in a variety of flavoring compositions.

Ethyl (2E,4Z,7Z)-2,4,7-decatrienoate and its use as a perfuming or

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.
