Qcm-based Polyphenol Monitoring for Enhanced Olive Cultivation

Polyphenols are plant-derived molecules that play several metabolic roles. In agricultural products, polyphenols content is considered a key quality marker, improving the antioxidant ability, preservation, colour, flavour, and aroma. In olive cultivation, the analysis of polyphenols levels in olive fruits is a biomarker for plant health and growth, environmental influences, and harvest quality. In this regard, the Quartz Crystal Microbalance (QCM) technique is highly versatile, enabling the detection of polyphenols in complex matrices such as olive derivatives. Its high precision in measuring mass changes allow for the detection and quantification of polyphenols in olive samples to monitor the ripening degree, to optimize the harvest planning, and to get high-quality products. In this work, we present the preparation of novel functional bio-derived polymers as probes for the functionalization of sensors for real-time polyphenols detection in a commercial quartz crystal microbalance equipped with a dissipation monitoring system (QCM-D). These probes were synthesized by simple coupling reactions and their ability to bind to olive polyphenols was evaluated. This platform offers a promising tool for rapid, accurate polyphenol detection, enabling improved quality control and optimization of olive cultivation and food production.
