Predictive modeling of allowable storage time of finger millet grains using artificial neural network and support vector regression approaches

The study aimed to establish safe storage guidelines for long-term preservation of finger millet grains and to develop a model for predicting the allowable storage time. The experiment was conducted at various temperature (15, 25, 35 and 45 degrees C) and moisture contents (8, 11, 14, 17 and 20% wb). Changes in response variables such as germination, free fatty acid and mold growth were systematically monitored. Finger millet with a moisture content above 14% should be dried to safe moisture levels within 3-5 weeks at 30 degrees C or within 5-10 weeks at 15 degrees C to preserve grain quality. To maintain high quality and seed viability of finger millet, moisture content and storage temperature should be below 12% and 20 degrees C, respectively for up to 34 weeks. The study also assessed the use of artificial neural network and support vector regression models in predicting the safe storage period for finger millet grains.
