Determining Moisture Content - Food Quality Safety

Feb 03, 2017 The drying oven, commonly used for commercial purposes, is the established reference method for loss on drying (LoD) by TGA. In this procedure, a sample is weighed and subsequently heated to allow for the release of moisture. Following this, the sample is cooled in the desiccator before reweighing. Moisture content is calculated by the ...

In conclusion, drying samples at 135C for 2 h is not appropriate for determining the moisture content in whey permeate, whey powder, or DDGS as well as the mixed diet containing these ingredients. The oven-drying method at 105C for 5 to 6 h appears to be appropriate for whey permeate and whey powder, and at 105C for 2 to 3 h for DDGS.

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.
