REVINE project : regenerative agricultural approaches to improve ecosystem services in Mediterranean vineyards

Viticulture became central to most western Mediterranean civilisations only a few millennia after grapevine (Vitis vinifera L.) was domesticated in the South Caucasus and the Near East.

Protein instability in wines is challenging, and despite many efforts to find satisfactory alternatives to bentonite, both in terms of stability and quality, the solutions are limited in the wine industry.

Resveratrol, a key polyphenol from grapes and red wine, and omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), abundant in Mediterranean dietary patterns,

Having the possibility to use a wide spectrum of elecromagnetic waves, dielectric spectroscopy is a technique commonly used for electrical characterization of dielectrics or that of materials with high energy storage capacity, just to name a few. Based on the electrical excitation of dipoles (polymer chains or molecules) or ions in relation to the characteristics of a weak external electric field, this method allows the measurement of the complex permittivity or impedance of polarizable materials, each component having a characteristic dipole moment.In recent years, the food industry has also benefited from the potential offered by this technique, whether for the evaluation of fruit quality or during the pasteurization of apple juice [1-3]. As the tests are fast and do not destroy the products, dielectric spectroscopy proved to be an experimental tool suitable for online measurements as well as long-term monitoring.

Following the acquired awareness of the presence of ochratoxin A in grape derivatives, actions were undertaken to contain this contamination, and attempts were made to evaluate the presence of any other molecule belonging to this class.
