Conservation advances on Physalis peruviana L. and Spondia purpurea: a review

Abstract

This research aims to describe the different methodologies that have been developed for the conservation of two fruits (Physalis peruviana L. and Spondia purpurea) present in the Ecuadorian highlands, as well as in other American countries. Information has been collected regarding the development of alternative and efficient technologies for the conservation of these fruits and their bioactive compounds. The studies performed to date are associated with the effect that the different conservation methods have shown in the post-harvest behavior (color, antioxidant potential, polyphenols, etc.) of the fruits, as well as its characterization in different maturation stages (soluble solids, acidity, pH, etc.). The contrast and comparison of this information will support choosing the most appropriate methodology according to the objectives to be achieved and the available resources. The research concludes that the knowledge about the healthy components in fruits increase their consumption and therefore motivates, the research to preserve these components for a longer time, reducing costs and waste.
