Abstract
Betacyanin microcapsules were made from betacyanin extract (extracted from red
dragon fruit peel) and coated with coating material, consist of maltodextrin + gum arabic. The
effect of heating on the stability of betacyanin content and color in beverage model containing
betacyanin were studied. Betacyanin microcapsules were applicate in water with different
pasteurization temperatures (65°C, 70°C, 75°C, 80°C) and time heating (10 minutes, 20 minutes,
and 30 minutes). The result showed betacyanin content was not significantly decreased after it
heated for 10 minutes to 20 minutes. This indicated betacyanin microcapsules from red dragon
peel was potential to be natural food colorant in beverage model
