Dimethylfuryl-dihydro-1,3,5-dithiazines are useful flavorings having low taste threshold values. They impart a coffee or mocha taste, in particular to drinks, confectionery and bakery products.

Dimethylfuryl-dihydro-1,3,5-dithiazines

The invention relates to new thio-alkanones of the formula ##STR1## in which X represents an oxygen or sulphur atom,

Thio-alkanones, process for their preparation and their use

New hemimercaptals of the formula ##STR1## in which X represents an oxygen or sulphur atom, a process for their preparation and their use as flavorings have been found.

Hemimercaptals, processes for their preparation, and edible compositions

A perfumed or edible composition comprising an appropriate carrier and an amount of 5-methyl-hept-2-en-4-one effective to impart its fragrance or flavor to the composition. It imparts a fragrance and flavor reminiscent of hazelnut.

Use of 5-methyl-hept-2-en-4-one as a fragrance and/or flavor

Unsymmetrical dihydrodithiazines of the formula ##STR1## in which one of the substituents R.sub.1 and R.sub.2 represent a C.sub.3 -C.sub.5 -alkyl group while the other is a methyl group and R.sub.3 represents a hydrogen atom, or R.sub.1 represents a methyl group and R.sub.2 and R.sub.3 together form a C.sub.3 -C.sub.4 -alkylene radical, a process for their preparation and their use as fragrances and flavorings.

Unsymmetrical dihydrodithiazines, and their use as fragrances and

Flavoring with 5-methyl-hept-2-en-4-one

Di- and tetrahydrobenzofuranone of the formula ##STR1## are useful in scenting and/or flavoring agents for imparting thereto a coumarin and coconut note.
