Dye and Metabolite Reference Materials
Les colorants sont largement utilisés dans divers secteurs, et les couleurs synthétiques sont populaires dans la production alimentaire en raison de facteurs tels que leur faible coût, leur résistance à la lumière et la stabilité de leur couleur.
Dans les analyses alimentaires, des aliments pour animaux et des boissons, les colorants peuvent relever de plusieurs catégories réglementaires principales : additif autorisé, autorisé mais sous surveillance/considéré comme préférable à éviter par certains groupes (comme les « six de Southampton »), et interdit/non autorisé.
Les substances interdites/non autorisées peuvent être des ingrédients planifiés qui deviennent non conformes s’ils sont exportés vers un autre pays ou ajoutés frauduleusement pour renforcer les couleurs naturelles (comme les colorants Sudan dans les épices), ou des résidus et métabolites de traitements vétérinaires autorisés qui persistent dans les produits animaux.
Nous proposons une large gamme de matériaux de référence pour colorants et métabolites, incluant de nombreux produits accrédités ISO/IEC 17034 et 17025. Notre portefeuille comprend également des colorants marqués isotopiquement tels que Sudan I-d5, ainsi que des mélanges de colorants azoïques ou de benzidines, ainsi que des colorants autorisés et interdits.
