Electrical Impedance Spectroscopy Techniques for Assessing Ageing, Mechanical Damage, and Chilling Injury in Fruit

Project title: Electrical Impedance Spectroscopy Techniques for Assessing Ageing, Mechanical Damage, and Chilling Injury in Fruit

Project description: This study explores the application of Electrical Impedance Spectroscopy (EIS) as a non-destructive technique for evaluating fruit quality, with a focus on detecting aging, mechanical damage, chilling injury, and ripening stages in various fruit tissues. By employing both contact-based and non-contact EIS approaches, the research aims to address the limitations of existing assessment methods in laboratory and industrial contexts. The contact-based method involves direct electrode application to the fruit surface, enabling high-resolution measurements of internal quality parameters such as moisture content, ripeness, and tissue integrity. In contrast, the non-contact method, employing capacitive impedance measurement provides a rapid, non-invasive solution suitable for large-scale operations by evaluating fruit quality without direct contact. The integration of these approaches creates a comprehensive framework that balances laboratory precision with industrial scalability, advancing sustainable, non-invasive methods for enhancing fruit quality assessment across the supply chain.
