Thiazoles, thiophene, thiazoline and thienyl derivatives.
European Parliament and Council Regulation (EC) N° 2232/96 sets out the basic rules for the use of flavouring substances in or on foodstuffs in the EU. It furthermore lays down a procedure for the establishment of a EU-wide positive list of flavouring substances. After its establishment only those flavouring substances listed may be added to foods.
The substances of the register are distributed in groups of structurally related compounds which are expected to show some metabolic and biological behaviour in common.
These chemical groups for flavouring substances are listed below.
|1||Straight-chain primary aliphatic alcohols/aldehydes/acids, acetals and esters with esters containing saturated alcohols and acetals containing saturated aldehydes. No aromatic or heteroaromatic moiety as a component of an ester or acetal.|
|2||Branched-chain primary aliphatic alcohols/aldehydes/acids, acetal and esters with esters containing branched-chain alcohols and acetals containing branched-chain aldehydes. No aromatic or heteroaromatic moiety as a component of an ester or acetal.|
|3||alpha, beta-unsaturated (alkene or alkyne) straight-chain and branched-chain aliphatic primary alcohols/aldehydes/acids, acetals and esters with esters containing alpha, beta-unsaturated alcohol and acetal containing alpha, beta-unsaturated alcohols or aldehydes. No aromatic or heteroaromatic moiety as a component of an ester or acetal.|
|4||Non-conjugated and accumulated unsaturated straight-chain and branched-chain aliphatic primary alcohols/aldehydes/acids, acetals and esters with esters containing unsaturated alcohols and acetals containing unsaturated alcohols or aldehydes. No aromatic or heteroaromatic moiety as a component of an ester or acetal.|
|5||Saturated and unsaturated aliphatic secondary alcohols/ketones/ketals/esters with esters containing secondary alcohols. No aromatic or heteroaromatic moiety as a component of an ester or ketal.|
|6||Aliphatic, alicyclic and aromatic saturated and unsaturated tertiary alcohols and esters with esters containing tertiary alcohols. Esters may contain any acid component.|
|7||Primary alicyclic saturated and unsaturated alcohols/aldehydes/acids/acetals/esters with esters containing alicyclic alcohols. Esters/acetals may contain aliphatic acyclic or alicylic acids or alcohol component.|
|8||Secondary alicyclic saturated and unsaturated alcohols/ketones/ketals/esters with ketals containing alicyclic alcohols or ketones and esters containing secondary alicyclic alcohols. Esters may contain aliphatic acyclic or alicyclic acid component.|
|9||Primary aliphatic saturated or unsaturated alcohols/aldehydes/acids/acetals/esters with a second primary, secondary or tertiary oxygenated functional group including aliphatic lactones.|
|10||Secondary aliphatic saturated or unsaturated alcohols/ketones/ketals/esters with a second secondary or tertiary oxygenated functional group.|
|11||Alicyclic and aromatic lactones.|
|12||Maltol derivatives and ketodioxane derivatives.|

|19||Capsaicin related substances and related amides.|
|20||Aliphatic and aromatic mono- and di- thiols and mono-, di-, tri-, and polysulfides with or without additional oxygenated functional groups.|

|25||Phenol derivatives containing ring-alkyl, ring-alkoxy, and side-chains with an oxygenated functional group.|
|26||Aromatic ethers including anisole derivatives.|
|28||Pyridine, pyrrole, and quinoline derivatives.|
|29||Thiazoles, thiophene, thiazoline and thienyl derivatives.|
