We proposed an innovative and economic method for rapid production of functionalized orange juice (OJ) with excellent nutritional properties, prolonged shelf life, and safe consumption. To reach this goal, we have employed direct current atmospheric pressure glow discharge, generated in contact with a flowing liquid cathode (FLC-dc-APGD) in a highly-throughput reaction-discharge system. It was found that controlled FLC-dc-APGD-treatment of OJ lead to increase the concentration of selected metals and phenolic compounds. The so-obtained OJ had the same qualitative composition of fragrance as the untreated one, however, its shelf life was prolonged up to 26 days. Furthermore, OJ exposed to FLC-dc-APGD-treatment did not exhibit any cytotoxic properties towards non-malignant human intestinal epithelial cell lines. On the other hand, the induction of cell cytotoxicity was observed in human colorectal adenocarcinoma cells line after FLC-dc-APGD-treated OJ application. We truly believe that produced by us functionalized OJ might be a tempting alternative to classic, non-treated by FLC-dc-APGD OJ.
我们提出了一种创新且经济的方法，可用于快速生产具有优异营养特性、延长保质期和安全消费的功能性橙汁（OJ）。为了实现这一目标，我们采用了在高通量反应-放电系统中与流动液体阴极（FLC-dc-APGD）接触产生的直流常压辉光放电。研究发现，OJ 的受控 FLC-dc-APGD 处理会导致所选金属和酚类化合物浓度增加。所得 OJ 的香气成分与未处理的 OJ 相同，但保质期延长至 26 天。此外，暴露于 FLC-dc-APGD 处理的 OJ 对非恶性人肠上皮细胞系没有任何细胞毒性。另一方面，在应用 FLC-dc-APGD 处理的 OJ 后，观察到人类结直肠腺癌细胞系的细胞毒性诱导。我们坚信，我们生产的功能性 OJ 可能是经典的、未经 FLC-dc-APGD 处理的 OJ 的诱人替代品。
