Comprehensive studies on the properties of apple juice treated by non-thermal atmospheric plasma in a flow-through system

A. Dzimitrowicz, A. Bielawska-pohl, et al.

This innovative study led by Anna Dzimitrowicz and colleagues reveals how a non-thermal atmospheric plasma system can enhance the nutritional content and shelf life of apple juice without compromising its quality. The findings suggest potential antitumor activity against colorectal adenocarcinoma cells, opening new avenues in food treatment and cancer research.

Abstract
This study optimized a non-thermal atmospheric plasma (NTAP) system for continuous-flow apple juice (AJ) treatment. The effects of various parameters (discharge current, flow rate, electrode distance) on AJ properties were investigated using design of experiments and response surface methodology. NTAP treatment increased the concentration of several minerals (Ca, Fe, K, Mg, Na, Sr, Al, B, Ba, Cu, Mn, Zn) and total phenolic content, while extending shelf life. Importantly, NTAP treatment did not alter the structure of organic compounds, °Brix value, color, or ferric ion reducing antioxidant power. Furthermore, the treated AJ showed no cytotoxicity towards non-malignant human cells but exhibited induced cytotoxicity in human colorectal adenocarcinoma cells, suggesting potential antitumor activity.
