  • Page 59 METER recommends offsetting the model to a primary reference method (Section 2.5.4). Once a moisture model is loaded on the AQUALAB 3, it will return a moisture content reading. Until a linear offset has been performed, this moisture content value should not be considered precise and should be discarded (Section 2.5.4).

This allows food manufacturers to decrease rework/waste and increase product consistency and make a significant business impact.
  • Page 75 SYSTEM nuclear magnetic resonance (NMR), may also be used. Moisture content determination is essential in meeting product nutritional labeling regulations, specifying recipes, and monitoring processes. However, moisture content alone is not a reliable indicator for predicting microbial responses and chemical reactions in materials. The limitations of moisture content measurement are attributed to differences in the intensity that water associates with other components.
  • Page 76 There are several advantages in having a temperature-controlled water activity meter. A few major reasons are detailed here.
  • Page 77 In order to infer moisture content from water activity, an isotherm for the particular product is needed. METER sells an isotherm generator called the AQUALAB Vapor Sorption Analyzer (VSA) or METER can run the isotherm for a fee.
