Polyvinyl alcohol film with chlorine dioxide microcapsules can be used for blueberry preservation by slow-release of chlorine dioxide gas.

ABSTRACT:

Introduction

Chlorine 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.

Methods

In 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.

Results

The self-releasing films had the best overall performance when the microcapsule content was 10% as the film's mechanical proper
