The organoleptic props. of tobacco and other prods. are improved or modified by adding (i) a cpd. of formula (I): R-C(O)NHR1 (where R and R1 are 1-6 alkyl or H); (ii) cycloaliphatic esters and ketones; (iii) phenol derivs.; (iv) heterocyclic ketones of formula (II): with a double bond in the posn. of 1 of the dotted lines, where X is H or OH if the double bond is in the ring, or O if the double bond is outside the ring; R2 and R3 are lower alkyl and Z is O or S; (v) caryophyllene derivs. or (vi) epoxy-beta-ionone, 6-methyl-hepta-3,5-diene-2-one, 3-isopropylcyclopent-2-ene-1-one, octa-3,5-diene-2-one, nonane-2,5,8-trione, 2-methyl-5-(alpha-methyl-alpha-hydroxyethyl)cyclohex-2-ene-1-one, or 4-methylthiobutan-2-one. Food, fodder, drinks and pharmaceuticals may be treated, as well as tobacco. The taste of tea, coffee and lime-flower tea can be modified; the additives may be used in meat, esp. smoked meat, and cocoa. |
