Why measuring moisture ?
Most natural products contain moisture. The water content per se is seldom of interest. Rather, it shows whether a product intended for trade and production has standard properties such as

• Storability
• Agglomeration in the case of powders
• Microbiolgical stability
• Flow properties, viscosity
• Dry substance content
• Concentration or purity
• Commercial grade (compliance with quality agreements)
• Nutritional value of the product
• Legal conformity (statutory regulations governing food)
