Abstract Moisture content plays a crucial role in determining the quality, shelf life, and market value of grains. Therefore, accurately measuring and detecting moisture levels is essential for efficient storage and processing. This study examines various methods used to determine moisture content, covering both traditional and modern techniques. Conventional methods like oven drying have been reliable for moisture measurement but often require more time and are unsuitable for real-time analysis. In contrast, advanced methods such as capacitance, microwave, and near-infrared (NIR) spectroscopy provide faster and more accurate measurements, often without damaging the grains. The study explores the principles, advantages, and limitations of each technique, focusing on their accuracy, efficiency, and cost-effectiveness. Experimental results highlight the effectiveness of non-destructive methods, which allow quick and precise evaluation without harming the grains. This emphasizes the importance of adopting modern moisture detection technologies in post-harvest management and agricultural practices to enhance food security and reduce waste in the grain supply chain. Given the impact of moisture content on grain quality, accurately and promptly detecting moisture levels is essential for farmers, grain handlers, and food processors. Modern moisture detection techniques provide real-time feedback, enabling operators to adjust storage conditions and processing parameters quickly. Capacitance-based methods measure the dielectric properties of grains, offering fast and non-invasive moisture readings. Microwave-based techniques use the interaction between microwave signals and water molecules in grains, providing high accuracy even in large quantities. Near-infrared spectroscopy (NIR) measures light absorption at specific wavelengths to estimate moisture levels, making it suitable for large-scale, continuous monitoring. The use of these advanced techniques improves post-harvest management by helping farmers and processors make better storage decisions, reduce spoilage, and maintain nutritional quality. Non-destructive methods are particularly valuable because they deliver rapid and precise results without affecting grain quality.
