DLA 01 - 09: 2 Samples with Allergens in a Food Matrix, as pastry, chocolate spread or sausage, are provided for qualitative and quantitative determination. One of these samples and the "Spiking Level Sample" were prepared adding the allergenic ingredients. The "Spiking Level Sample" contains the allergens in a simple matrix in similar amounts.
