Microencapsulación de aceites mediante secado por aspersión: avances, beneficios y aplicaciones en América Latina

Abstract

Spray drying Microencapsulation applied to oils is a technique with great potential to provide protection to various formulations susceptible to physicochemical degradation. Knowing the current state of this technique and the extent of the studies concerning this matter in Latin America is essential to devise the next steps to take for the development of this technique. The analysis of 42 investigations published in indexed scientific journals with the participation of Researchers in Latin America was carried out, studying the type of oil, encapsulation matrix, additives and homogenization methods of the emulsions, scale of the drying process and the properties of the final product. After the review of the articles, a growing number of publications were observed with the aim of evaluating new formulations of a great variety of encapsulated vegetable, animal, and essential oils to preserve their properties for longer periods of time, giving these oils more versatility to be incorporated into food formulations. In the end, it can be stated that although there have been a great variety of studies in Latin America on encapsulation of oils by spray drying, there are still many fields to be covered and opportunities are open to continue with the experimentation of encapsulation of new oils. optimization of the parameters and scaling of these processes.
