Aplicación de la técnica de microencapsulación de betalaínas extraídas a partir de la remolacha (Beta vulgaris)

Abstract

The present research work establishes the application of the microencapsulation technique of betalains extracted from beetroot. The parts of the beetroot studied are the leaves, the husk and the pulp, obtaining by spectrophotometry that the part of the beetroot with the highest content of betalains are the leaves. The determination of antioxidant activity of the encapsulated samples indicates that the best microcapsulating agent of betalains is maltodextrin with gelatin. The betalains are degraded between 50 to 80 Celsius degrees, forming dehydrogenated products of yellow coloration; maintaining an endothermic behavior between 28.6 Celsius degrees to 128.7 Celsius degrees.
