Abstract
New cycloaliphatic unsaturated ketones and their use as perfuming and odor-modifying agents in the manufacture of perfumes and perfumed products, and as flavoring and taste-modifying agents in the preparation of foodstuffs in general and imitation flavors for foodstuffs, beverages, animal feeds, pharmaceutical preparations and tobacco products. Methods for the preparation of said cycloaliphatic unsaturated ketones.
Claims14
A flavouring composition having incorporated therein as a taste- and flavour-modifying agent to develop fruity, herb-like, winy, woody, floral or waxy flavour notes from about 0.1% to 15% by weight of a substantially pure compound having the formula ##STR40## containing one double bond in position 2'- or 3'- of the acyl side-chain and either one double bond in position 1- or 2- or two conjugated double bonds in positions 1- and 3- of the ring, the double bonds being represented by dotted lines, and wherein n is zero or 1, R.sup.1, R.sup.2 and R.sup.3 represents hydrogen or one of them a lower alkyl radical and the others hydrogen, and R.sup.4, R.sup.5, R.sup.6 and R.sup.7 represent hydrogen or one of them a lower alkyl radical and the others hydrogen.
A composition selected from the group consisting of foodstuffs, animal feeds and beverages which comprises having added thereto from about 0.1 ppm to about 100 ppm of a substantially pure compound having the formula ##STR41## containing one double bond in position 2'- or 3' of the acyl side chain and either one double bond in position 1- or 2- or two conjugated double bonds in positions 1- and 3- of the ring, the double bonds being represented by dotted lines, and wherein n is 0 or 1, R.sup.1, R.sup.2 and R.sup.3 represent hydrogen or one of them a lower alkyl radical and the others hydrogen, and R.sup.4, R.sup.5, R.sup.6, and R.sup.7 represent hydrogen or one of them a lower alkyl radical and the others hydrogen, to develop in the said foodstuff, animal feed or beverage, a fruity, herb-like, winy, woody, floral or waxy flavor note or any combination of these flavor notes.
A method for modifying, enhancing or improving the organoleptic properties of flavouring compositions, which comprising incorporating in said materials as a taste- and flavour-modifying agent to develop fruity, herb-like, winy, woody, floral or waxy flavour notes from about 0.1% to 15% by weight of a substantially pure compound having the formula ##STR45## containing one double bond in position 2'- or 3'- of the acyl side-chain and either one double bond in position 1- or 2- or two conjugated double bonds in positions 1- and 3- of the ring, the double bonds being represented by dotted lines, and wherein n is zero or 1, R.sup.1, R.sup.2 and R.sup.3 represent hydrogen or one of them a lower alkyl radical and the others hydrogen, and R.sup.4, R.sup.5, R.sup.6 and R.sup.7 represent hydrogen or one of them a lower alkyl radical and the others hydrogen.
A method for modifying, enhancing or improving the taste and flavour of foodstuffs, beverages or animal feeds which comprises incorporating in said materials from about 0.1 ppm to about 100 ppm of a substantially pure compound having the formula ##STR46## containing one double bond in position 2'- or 3' of the acyl side chain and either one double bond in position 1- or 2- or two conjugated double bonds in positions 1- and 3- of the ring, the double bonds being represented by dotted lines, and wherein n is 0 or 1, R.sup.1, R.sup.2 and R.sup.3 represent hydrogen or one of them a lower alkyl radical and the others hydrogen, and R.sup.4, R.sup.5, R.sup.6, and R.sup.7 represent hydrogen or one of them a lower alkyl radical and the others hydrogen, to develop in the said foodstuff, animal feed or beverage, a fruity, herb-like, winy, woody, floral or waxy flavor note or any combination of these flavor notes.
