Direct Moisture Determination of Food and Feed Samples Comparing Automated Thermogravimetric and Air Oven loss-on-drying Techniques

<p>Accurate moisture content determination is critical to ensure product quality, consistency, and safety in both food and feed industries. Moisture levels affect texture, taste, and microbial stability, and are key factors in calculating purity, yield, and constituent analysis on a dry basis.</p> <p>One of the most widely used direct moisture determination methods is the loss-on-drying (LOD) technique, where a sample is weighed before and after being heated in a ventilated air oven. The mass loss after drying represents the moisture content of the sample.</p> <p>Standardized AOAC loss-on-drying methods, including AOAC 925.10 for food and AOAC 930.15 for feed, have long been recognized as reliable approaches for moisture analysis. The LECO TGM800 Thermogravimetric Moisture Analyzer provides a fully automated AOAC-compliant solution. meeting method requirements for sample mass, oven temperature, and air flow.</p>
