QA/QC in Beverage Production: Cocoa Mix and Powdered Drinks

To achieve good solubility, the particulates contained in powdered beverages are most often engineered to be very fine. Thus, visual examination or a conventional macroscopic analysis usually cannot or only partially provide the necessary information about the product. Advanced analytical methods are required to accurately analyse the composition of powdered beverages. FT-IR imaging enables identification of foreign contaminants as well as the individual major ingredients in a mixture by creating a chemical map to visualise the overall distribution.
