Abstract. Understanding the hydration characteristics of different cereals and legumes is important for gaining insights into their processability and for determining seed dormancy. Hydration kinetics can also provide valuable information on the hydration rate and extent of volume and weight uptake. In this study, a seed hydration analysis system was developed for application in research and industry, where there is a need to understand hydration rates of seeds. The system is able to simultaneously soak seeds and measure their volume, weight, and density. The system also records and presents data in real time using a computer. The system was successfully evaluated to measure volume and weight with 97.87% and 99.08% accuracy, respectively. Examples of the scope of the hydration analysis system are also presented.
