Laboratory reference materials for dioxins and furans in milk powder
Milk powders spiked with different quantities of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) have been prepared by both freeze-drying and spray-drying. The spray-dried batches have been compared with the freeze-dried ones. The homogeneity of both batches has been verified by determining the PCB, fat and Kjeldahl nitrogen content and the stability was checked using similar tests. The results obtained show that there is no significant difference between the materials and the results can therefore be used as indicative values for the spray-dried laboratory reference material.
