ABSTRACT
The effect of air temperature (50°C, 60°C, 70°C, 80°C and 90°C) and pre-treatments (steam, water palm oil-water, groundnut oil-water blanching) on the drying characteristics and quality of bell pepper was investigated. The results were fitted to six thin-layer drying models and Parabolic model gave the best fit. The pretreated samples dried faster than untreated samples and had lower values of total energy needed and specific energy requirement. The ascorbic acid content, color and rehydration index varied from 129.1 to 316.8 mg/100 g dry matter, 0.1 to 0.9, 22 to 33 mL and pretreated dried pepper generally had higher values than untreated samples. INSET: 18.

    Despite the interest in growing raspberries ( Rubus idaeus) in the southeastern USA, production is limited by the lack of cultivars adapted to the climate. One of these major climate adaptations is the ability to tolerate fluctuating winter temperatures. Perennial plants have adapted to these...
