a The experiments were performed using a thermogravimetric analyzer at 30 °C and a N2 flow of 1.0 mL min−1. k and t50% represent the release rate constant and the times required for the release of 50% of the fragrance, respectively. b R2, the values of the correlation coefficient to the mathematical model; n, the exponent in the Weibull equation.
