Encapsulation of betacyanins and polyphenols extracted from leaves and stems of beetroot in Ca(II)-alginate beads: A structural study

The aim of this work was to use the recovery of antioxidant compounds (betacyanin and polyphenols) derived from beetroot industrial wastes (stems and leaves), and their subsequent encapsulation in Ca(II)-alginate beads containing sugars, providing a detailed structural characterization of these syst...
