Storage stability of encapsulated anthocyanin-rich extract from black carrot (Daucus carota ssp. Sativus) using different coating materials

Abstract

The enzymatic assisted cum hydraulic pressed extract of black carrot which has high anthocyanin content were encapsulated through spray drier using a mixture of Jack fruit seed starch, Soy protein and NBRE-15 (SET -1) and in the second set of experiment using Jack fruit seed starch, Whey protein and NBRE-15 (SET-2) as coating materials. The quality attributes of the powders which were produced at an optimum mixture of SET -1 and SET-2 were characterized by anthocyanin content, antioxidant capacity and L*, a*, b*, C and Hº value. It was reported that SET-1 was found better-encapsulating material as compared to SET-2. SET-1 had higher retention of anthocyanin content, colour, antioxidant activity during storage at 25 ºC.
