Article UV-Shielding Biopolymer Coatings Loaded With Bioactive Compounds for Food Packaging Applications(MDPI, 2025) Gennaro, Matteo; Buyuktas, Duygu; Carullo, Daniele; Pinto, Andrea; Dallavalle, Sabrina; Farris, StefanoFour natural bioactive compounds with UV-absorbing properties-curcumin, quercetin, caffeic acid, and hymecromone-were incorporated into pectin-based coatings deposited on oriented polypropylene (OPP) to develop packaging films with UV-shielding capabilities. The effects of both bioactive compounds (used individually or in combination) and coating thickness (delta = 0.12-1.2 mu m) on the optical properties (UV-Vis transmittance and haze) of the coated OPP samples were investigated. Coating deposition enhanced the UV-barrier properties in relation to the type of bioactive compound, following the order of caffeic acid > hymecromone > curcumin > quercetin. Regardless of the type of bioactive compound used, no significant changes were observed in clarity, haze, and tensile parameters of OPP, whereas the pectin coatings dramatically improved the oxygen barrier performance of the plastic substrate. Additionally, a greater coating thickness resulted in a lower UV-light transmittance of coated PP films. Although the combination of hymecromone and caffeic acid did not exhibit a synergistic effect, it demonstrated an additive benefit, effectively broadening the wavelength range of UV protection in the final packaging materials. While this study highlights that a performance gap remains compared to commercially available UV-shielding materials, it underscores the potential of replacing synthetic UV-absorbing additives with natural compounds through coating technologies rather than masterbatch incorporation.Review Citation - WoS: 41Citation - Scopus: 43Electrochemical Sensors in the Food Sector: a Review(American Chemical Society, 2024) Ghaani, Masoud; Azimzadeh, Mostafa; Büyüktaş, Duygu; Carullo, Daniele; Farris, StefanoIn a world that is becoming increasingly concerned with health, safety, and the sustainability of food supply chains, the control and assurance of food quality have become of utmost importance. This review examines the application and potential of electrochemical sensors in the dynamic field of food science to meet these expanding demands. The article introduces electrochemical sensors and describes their operational mechanics and the components contributing to their function. A summary of the most prevalent electrochemical methods outlines the diverse food analysis techniques available. The review shifts to discussing the food science applications of these sensors, highlighting their crucial role in detecting compounds in food samples like meat, fish, juice, and milk for contemporary quality control. This paper showcases electrochemical sensors' utility in food analysis, underscoring their significance as powerful, efficient tools for maintaining food safety and how they could transform our approach to global food quality control and assurance.
