This Technical Specification specifies an ELISA-method for the determination of hazelnut concentration in food samples.Spiking experiments using diluted ground hazelnut have been used to validate the method’s use on food matrices such as mixed grain cereals, dark chocolate (45 % cocoa) and ice cream. The range of the method is 0,5 mg to 5,0 mg hazelnut protein per kg of food sample. As hazelnut kernels typically contain between 12 % to 15 % protein [2], [3], this equates to approximately 3,7 mg to 37 mg hazelnut kernel per kg of food sample. The upper limit of the range of quantitation can be extended, if required, by further dilution of sample extracts.The method is commercially available ) and has been validated in-house by the manufacturer. The data is included in A.2.The method has been successfully validated by a collaborative study. The study was organized by the Working Group established by the Federal Office of Consumer Protection and Food Safety (BVL) for the execution of § 64 of the German Food and Feed Code (LFGB) for the determination of hazelnut content in dark chocolate. Thirteen German laboratories participated. The data are included in A.3.
