The invention concerns delayed release flavourant compositions.
In particular, these compositions are selected from the group consisting of
a) smoking compositions and
b) foodstuffs, in particular
b1) bakeable foodstuffs and
b2) microwaveable foodstuffs
containing flavour-release additives, namely 1,2―diols of the formula
wherein R1 is one of the radicals
where
R2 isH, lower alkyl
R3, R4 areH, lower alkyl, lower alkoxy, hydroxy, or R3 + R4 together are methylenedioxy,
R5 islower alkyl
and the broken lines represent in the ring one additional bond
and in the side chain an optional bond.
