A novel method to prolong bread shelf life: Sachets containing essential oils components

Traditional packaging has reached its limits in ensuring food quality and prolonging shelf life. In this study, we developed antifungal sachets containing essential oils (EOs) in microcapsules (ASEOs-CM) and evaluated their application potential in bread preservation. The results showed that the release of EOs from ASEOs-CM at 25 degrees C followed first-order kinetics. In addition, EOs-containing ASEOs-CM had strong inhibitory effects on microorganisms in vitro and effectively inhibited the growth of molds and yeasts on sliced bread. In the experimental group, the contents of eugenol and citral EOs on bread increased during storage. Breads in three different packages (LDPE, PP and HDPE) had a total shelf life of 13, 13, and 15 d, respectively, while control breads had a shelf life of 5 d. Sachets did not affect the sensory properties of bread. Therefore, the use of ASEOs-CM was an effective, safe, and sustainable preservation method for breads.
