Drying gives dried samples lower nutritional quality than fresh samples because of physiological changes that takes place. Pretreatments of pepper by steam and by water blanching are common methods, but osmotic dehydration also has a significant effect on the quality of dried foods. The effect of the pretreatments and drying methods on the drying rate and nutritional quality of dried pepper were investigated. Osmotically dehydrated samples had the lowest drying time, while pretreated samples dried faster than untreated samples generally. The nutritional quality of the dried samples, however, varied with the different pretreatment methods. This indicates that pretreatment enhances drying rate and also affects the quality of the final dried product. Dried pepper can thus be pretreated with blanching or dipping in osmotic solutions for products of higher nutritional quality. This will give dried pepper that will meet the nutritional requirement of the consumers better than untreated dried pepper.
