Percentage of cumulative in vitro release profiles of (a) microcapsules containing citric acid: M30(16)C(80), M45(16)C(80), and M80(12)C(80); (b) microcapsules containing naringin: M30(16)N(5), M45(16)N(5), and M80(12)N(5), under different pH solutions. The release values displayed in the graphs are an average of three independent release experiments employing microcapsules of the same type, but from different batches (error bars represent standard deviations, ) [134].
