DETERMINATION OF MOISTURE CONTENT

Drying: moisture measurement at the end of drying is essential to follow up drying course and to decide whether it is achieved or not. On one hand, too long a drying course may have bad consequences for quality and food safety because of unexpected fermentations and mould growth. On the other hand, the next step in the process is storage.
