- Abstract
Different methods of sterilization are used in food packaging for the packaging of raw or processed foods. The use of gamma radiation as a sterilizing source of packaging does not alter several fundamental aspects of food, besides increasing the shelf life and freshness of food. The application doses are in the range between 10 and 50 kGy, with the dose of 25 kGy being the most used. Thus, this work aims to analyze the influence of the dose of 25 kGy on the properties of the film of PBAT – poly (butylene adipate co‐terephthalate) additivated with orange essential oil. In the results, it is identified, by FTIR and PCA, that the irradiation alters PBAT's vibrational modes. Films additivated with 10% oil show minor changes in the mechanical properties of tensile strength. But, in general, from the results obtained, all films are still fit for application as active packaging.
