Abstract:
:The objective of the present study was to investigate the effect of different combinations of carrier agents (Maltodextrin, gum arabic and whey protein concentrate) on the emulsion properties, encapsulation efficiency and oxidative stability of encapsulated drumstick oil powder (EDOP), produced by spray drying to increase its usage as an active ingredient. Feed emulsion characteristics were studied in terms of emulsion stability, droplet size, viscosity and surface charge. Obtained spray dried EDOP was characterized for physical and flow properties, microstructure and oxidative stability. EDOP obtained from the MD:GA emulsion showed higher encapsulation efficiency than MD:WPC. Higher encapsulation efficiency along with medium flow properties and better oxidative stability was observed with microcapsules obtained by MD:GA carrier agent. Microstructure of EDOP with MD:GA showed no cracks, smother appearance with continuous wall. EDOP with MD:GA had better stability and were stable at 45°C, which confirms the protective effect of this carrier agent in encapsulating the drumstick oil.
