| Summary, etc. | Moringa oleifera L is a nutrient-rich plant gaining global popularity for its health benefits, but its leaves are highly perishable and require effective drying methods to preserve their proximate analytes. This study optimized the drying conditions of the leaves at different maturity stages using an Automated Multi Commodity Heat Pump Dryer (AMCHPD), specifically, a) comparing the nutritional outcomes to traditional methods and commercial powders, b) to identify the best drying techniques for maintaining their nutritional quality, and c) to determine the drying kinetics of malunggay leaves. An experimental approach to examine the drying of Moringa oleifera with the AMCHPD, varying temperature and humidity, and analyzing drying kinetics through Origin statistical software. It involved drying leaves of different maturities, powdering them, and assessing nutritional parameters like crude protein, crude fiber, and ash content. The research focused on determining optimal drying conditions to preserve proximate analysis, and analyzing the physical and nutritional characteristics of the powdered leaves. The drying kinetics data were fitted to several mathematical models, with the Page model providing the best fit. Proximate analysis revealed variations at 2 weeks old, crude protein 29.86%, crude fiber 5.14%, moisture 8%, and ash 7.01%, 3 weeks old, crude protein 29.16%, crude fiber 5.24% moisture 7.56%, ash 9.04%, 4 weeks old, crude protein 30.76%, crude fiber 5.32, moisture 6.99%, ash 9.31%, 5 weeks old, crude protein 28.10%, crude fiber 5.35%, moisture 6.74%, ash 9.98% across different maturity levels. The drying results showed that drying time decreased with increasing temperature, and all tested temperatures 40℃, 50℃, 60℃ effectively reduced moisture content at 11.0%. The Page model provided the best fit for drying kinetics. Color analysis showed that the powder became less bright and more greenish as it dried. |
