Application of dehydration technologies as a tool to foster bioeconomics and fruit consumption in rural populations in South America

Abstract

Strengthening the use and improvement of species native to South America may lead to the development of new food products with high nutritional potential, in addition to contributing to disease prevention, thus meeting the varied demands of consumption. The focus of this strategy is especially on native plant species and/or introduced species, but which have become very popular for presenting edible fruits appreciated for their characteristic flavor and aroma. In addition, the pulp of such fruits has antioxidant potential, which makes it possible to call them functional foods. However, perishability and seasonality hinder production on a larger scale, and it is necessary to explore conservation alternatives to make the fruit pulp available all year round. Studies have shown the use of conventional technologies and emerging and promising technologies for the preservation of the organoleptic characteristics of fruits. Finally, the strengths and weaknesses of each conservation technique are discussed in view of the variety of fruits found in different regions of the world and especially in South American countries.
