Adding physiological fruit drop extracts of Citrus aurantium L. var Daidai into pullulan/bacterial cellulose packaging film improves the film's properties and effectively maintains the quality of strawberries.
The comprehensive utilisation of food waste has become a global development demand for enhancing their added value. This study aimed to develop and utilise physiological fruit drop of Citrus aurantium L. var Daidai with rich phenolic acids and flavonoids. Therefore, different concentrations (1%, 3%, 5%, 10% wt, based on pullulan weight) of daidai physiological fruit drop extracts (DE) were incorporated into pullulan/bacterial cellulose (BC) packaging film (PB2-DE). The effects of different concentrations of DE on composite films were comprehensively evaluated. It was found that the mechanical properties, ultraviolet barrier properties, and antioxidant properties of the films were improved with the addition of DE. Moreover, application tests have verified that films containing DE can effectively maintain the attractive quality of strawberries. Conclusively, the results demonstrated the feasibility of DE incorporation into films to increase the value of the waste and the potential applicability of films containing DE in strawberry preservation. Limes physiological fruit drop extracts were added to Pullulan/BC film to effectively preserve strawberries.image
