| description | Tea extract is a treasure house of bioactive polyphenol with several health benefits. Use of tea polyphenol in the food product matrix is limited as it is unstable during the handling and processing that even persists during storage. This study develops tea polyphenol microcapsules using Abroma augusta mucilage polysaccharide as a continuous phase. Abroma augusta mucilage (AAM) microcapsules containing tea polyphenol were developed using evaporation-induced self-assembly. The developed microcapsules with varying polyphenol concentrations were in size range of 100 to 250 nm range. High-Resolution Transmission Electron Microscope (HRTEM) further explored that individual microcapsules were composed of smaller particles of ∼ 25 nm size. The microcapsules with encapsulation efficiency above 90% offered pH-dependent release behaviour with an optimum release at neutral pH. Microcapsules offered protection to green tea polyphenol during thermal treatment at 80°C for 20 min. After hydration, microcapsules didn't alter the shear-thinning flow behaviorof the AAM polysaccharide and offered sensory acceptability as a viscous tea infusion. Thus, encapsulated green tea polyphenol could successfully be used as viscous tea infusion for antioxidant delivery. |
