| Popis: | The use of biobased active packing materials is a trend on the food industry especially when natural additives are incorporated. Polysuccinimide is an environmentally friendly biomaterial with no mutagenic effect. The aim of this work is to study the antimicrobial capacity of polysuccinimide functionalized with Oregano’s essential oil and its components migration. Polysuccinimide was obtained by self-condensation thermal reaction of aspartic acid and further functionalization with extracts of oregano’s essential oil. The biomaterial was characterized by Fourier transform infrared spectroscopy, antibacterial activity and migration analysis. The material functionalized at 3% showed antimicrobial efficiency against Escherichia coli and Staphylococcus aureus, with inhibitory halos of 4.00 cm. No migration of thymol and carvacrol was detected which is associated to prolonged release. This is widely sought in materials for biomedical and food fields. |
