“…Studies have shown that blueberries are rich in many biologically beneficial compounds, including anthocyanins, glucose, fructose, vitamins (A, D, and E), folic acid, minerals (such as phosphorus, potassium, and magnesium), and organic acids ( 1 , 2 ), which have high healthcare value and development prospects ( 3 ). However, owing to their thin skin and lack of hard shell protection, blueberries are susceptible to mechanical damage during harvest, transportation, and storage ( 4 – 6 ), which leads to the susceptibility of blueberries to microbial infestation after harvest ( 7 , 8 ). Mold is a common cause of blueberry rot, which affects its quality and reduces the economic benefit of the blueberry industry.…”

IntroductionChlorine dioxide (ClO2) is a safe and efficient bactericide with unique advantages in reducing foodborne illnesses, inhibiting microbial growth, and maintaining the nutritional quality of food. However, gaseous ClO2 is sensitive to heat, vibration, and light, which limits its application.MethodsIn this study, a ClO2 precursor-stabilized ClO2 aqueous solution was encapsulated by the double emulsion method, and a high-performance ClO2 self-releasing polyvinyl alcohol (PVA) film was prepared to investigate its performance and effect on blueberry quality during storage.ResultsThe self-releasing films had the best overall performance when the microcapsule content was 10% as the film's mechanical properties, thermal stability, and film barrier properties were significantly improved. The inhibition rates of Listeria monocytogenes and Escherichia coli were 93.69% and 95.55%, respectively, and the mycelial growth of Staphylococcus griseus was successfully inhibited. The resulting ClO2 self-releasing films were used for blueberry preservation, and an experimental study found that the ClO2 self-releasing antimicrobial film group delayed the quality decline of blueberries. During the 14-day storage period, no mold contamination was observed in the ClO2 self-releasing film group, and blueberries in the antibacterial film group had higher anthocyanin accumulation during the storage period.DiscussionResearch analysis showed that films containing ClO2 microcapsules are promising materials for future fruit and vegetable packaging.
