The present study evaluates the effect of osmotic dehydration (OD) of slices of creole apple harvested in the state of Guerrero in an emulsion (600 g solid kg-1 emulsion) prepared with capsul, jamaica and an oleoresin of piquin chili r adurante120 min at 40 °C. In addition, the apple was osmodehydrated in a solution of sucrose and sucrose-jamaica for comparison purposes. The influence of OD on water loss and on the gain of solids during the process was analyzed. In the same direction, the color change, the oil gain, the content of soluble phenols and monomeric anthocyanins were determined, as well as the maximum compression force of the lyophilized osmodehydrated slices. The samples treated with the emulsion showed an increase in the content of oil, soluble phenols and monomeric anthocyanins. The presence of jamaica in the osmotic solution favored the color change of the samples. The micrographs of the osmodehydrated slices with the emulsion revealed the presence of microcapsules with oil soaked in the microstructure of the apple. The obtained results suggest that this technique can be used to impregnate apple slices with oils and functional substances to produce more attractive foods for the consumer.
