Abstract


The objective of this study was to evaluate the effect of indirect solar drying (ISD) and conventional (CD) (40, 50, 60 °C) on the concentration of phenolic compounds of strawberry slices, coated with opuntia mucilage (Opuntia ficus indica), and measured with the spectrophotometric method. The indirect solar dryer uses solar-thermal and photovoltaic technology with temperatures between 40 and 60 °C. The concentration of anthocyanins was higher in the ISD than in CD. The strawberry coated with the nopal mucilage has a preservation of phenolic compounds in CD and IDS.
