Control of moisture in cookies, crackers, biscuits, and crispbreads is necessary in order to optimize the quality of the product and the production process. Moisture measurements can be made on or off-line. Online measurements greatly improve efficiency; they eliminate the need for routine laboratory moisture testing and provide an instantaneous measurement so that necessary process changes can be implemented sooner. Offline moisture measurements are simple, sample a greater product area, and are quicker than using Infrared balances or oven tests.
