Encapsulation Potential
Research confirms tara gum as a promising natural polymer for encapsulation � protecting and delivering bioactive compounds with stability and controlled release.
Key Properties
Spray-dried tara gum: particle size D50 = 3.46 �m, spherical shape, smooth surface. Glass transition temp: 141.69�C (comparable to maltodextrin 155�C, gum arabic 140�C). Low moisture (8.63%), water activity (0.37), hygroscopicity � good storage stability.
Best Drying Method
Among spray drying, forced convection, and vacuum drying, spray-dried tara gum showed best physicochemical characteristics: higher lightness, smallest particles, superior thermal properties.
Future Applications
Promising for encapsulating vitamins, probiotics, flavors, and pharmaceuticals. Research recommends continued investigation into practical food and pharma applications.
