challenges in measuring moisture content of

Furthermore, the maximum permissible moisture content in certain products may be governed by legislation (e.g. national food regulations). Typically, moisture content is determined via a thermogravimetric approach, i.e. by loss on drying, in which the sample is heated and the weight loss due to evaporation of moisture is recorded.Learn the Six Methods For Determining Moisture - Kett2017-10-8 · The original primary moisture measurement method was Loss On Drying (LOD). In an LOD test, the sample is weighed, dried, and weighed again. The difference in the two weights (Loss on Drying) is then compared with either the original weight (Wet-base test) or final weight (Dry-base test) and the moisture content calculated.
