Abstract

In this paper we present both results obtained by numerical modeling and experimental results of grape processing in high frequency electromagnetic field. Numerical modeling was performed with the HFSS 15.0 software for the processing in high frequency field. Experimental determinations were made with an applicator with adjustable power from 100 to 1000 W. The following varieties of grapes were processed: Muscat Ottonel, Merlot, and Pinot Noir (harvested in the Crisana-Santimreu vineyard in 2014). The three chosen varieties are characterized by different color and aroma. In our research we aimed at establishing effective processing techniques both in terms of energy and to obtain a high quality final product.
