Influence of different pectins on powder characteristics of microencapsulated anthocyanins and their impact on drug retention of shellac coated granulate

► Pectin and caffeine are copigments for anthocyanins. ► Anthocyanin rich blueberry extract is spray dried using pectins and caffeine. ► These additives have no influence on the morphology of spray dried microcapsules. ► Initial retention of anthocyanins in SGF depends on the waterbinding capacity. ► The higher the waterbinding capacity, the lower the anthocyanin release.
