In the experimental codes, capitals, N and C, refers to microcapsules prepared by spray drying from the mixtures without and with anhydrous citric acid, respectively. Next to a capital, two-digit numbers, 00, 05, and 10, means the mixing ratios (15:0, 15:5, and 15:10, respectively) of either waxy corn starch-anhydrous citric acid or waxy corn starch and Ainsliaea acerifolia extract, based on their respective total solid contents.
WCS, waxy corn starch; CA, anhydrous citric acid; AA, Ainsliaea acerifolia extract; EC, encapsulation capacity
Mean values of three measurements; Values sharing the same lowercase letters within columns are not significantly different (p<0.05).
