Resumen

Nowadays, with the demand for healthier foods, the market opportunities for healthier sweeteners allow lucuma flour entrance, as a good alternative. Lucuma (Pouteria lucuma) is a native fruit from Peru, Ecuador and Chile regions. The objective was to elaborate lucuma flour by convection drying at different temperatures and to evaluate its characteristics of centesimal and microbiological compositions and to compare the results with a product commercial sample (4). The samples were dried in a tray dryer with hot air at 2 m/s speed, at temperatures of 55°C, 65°C, and 75°C (Samples 1, 2 and 3, respectively). The total drying time of Sample 1 was longer than Sample 3, which obtained shorter drying time. The evaluated samples presented difference for moisture, ashes and fibers content. The protein contents of prepared samples did not differ significantly among them. The samples differed from each other for vitamin C content and the higher drying temperature presented higher effect on this compound loss. The samples were within microbiological standards established by legislation. Only Sample 4 satisfied granulometry standards. The centesimal composition final results indicated that temperature is an interfering parameter in lucuma flour nutritional quality, in such a way that the higher temperature used in the process, higher the nutritional loss.
