The Green Extraction of Blueberry By-Products: An Evaluation of the Bioactive Potential of the Anthocyanin/Polyphenol Fraction
In the context of a circular economy, this study published by the Department of Drug Science and Technology (Dipartimento di Scienza e Tecnologia del Farmaco) explores the valorization of blueberry pomace (BP) as a source of bioactive compounds through sustainable extraction methods.
This study provides a robust framework for the valorization of agri-food by-products, contributing to sustainable development and the advancement of natural bioactive products.
The integration of green extraction technologies and the circular economy model can drive innovation, promoting the development of effective and ecofriendly production.
The antioxidant activity of the extracts was measured using the BRS device (BQC Redox Technologies), designed for precise and rapid redox state assessment.
For the determination, blueberry pomace extracts were solubilized in distilled water and subsequently diluted in a 1:1 ratio with the BRS electrolyte solution. Each assay utilized a BRS disposable strip, with 50 µL of the solution being applied to the test area. Measurements are expressed in microcoulombs (µC) and were converted to Trolox equivalents via a calibration curve integrated within the device.
