Abstract
The release kinetics of nisin from poly(butylene adipate-
co-terephthalate) (PBAT) to distilled water was studied at of 5.6, 22 and 40
°C. The release kinetics of nisin from PBAT film was described using Fick’s second law of diffusion, partition coefficient, and Weibull model. The diffusion coefficients (
D) determined were 0.93, 2.29, and 5.78
