Methods for moisture and water content determinations
The moisture content influences the physical properties of a substance such as weight, density, viscosity, refractive index, electrical conductivity and many more. Chemical, thermogravimetric or loss on drying techniques are used to determine this content.
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)
