Physicochemical and Thermal Evaluation of a Mixed-Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.). [PDF]
J Food SciABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...
