Description

In Portugal, pears are traditionally dried by a direct sun-exposure method. However, because of the disadvantages associated with this procedure, alternative dryings are being tested. The objectives of this study were to evaluate how drying influences the color of pears, and to compare the products dried through different systems, to evaluate which one allows obtaining a product as much as possible with the same color of the traditional pears. From the results obtained was possible to see that dryings in systems with exposure to the sun (through glass) allow obtaining products that do not differ much from the traditional dried pears.
