A method of beverage (wine, fruit juice) deoxygenation has been developed using electrochemically regenerated metal chelates to remove the oxygen from a recycling gas stream. The gas stream which is used to deoxygenate the beverage is fed to the electrochemically regenerated metal chelate solution where the oxygen is selectively removed. The gas is then returned to the beverage to further deoxygenate the fluid. The system has the advantage that flavor components are not removed. The reaction of the metal chelates with the oxygen is not completely effficient, resulting in the production of off-flavors. This project addresses this chemistry which must be improved before the system can be practical. Metal chelate chemistry in the presence of oxygen and beverage flavor components is to be studied.

研究了一种利用电化学再生金属螯合物去除循环气流中的氧气的饮料（葡萄酒、果汁）脱氧方法。用于饮料脱氧的气流被送入电化学再生的金属螯合溶液，其中氧被选择性地去除。然后将气体返回到饮料中，进一步使液体脱氧。该系统的优点是风味成分不会被去除。金属螯合物与氧的反应不是完全有效，导致产生异味。该项目解决了在系统实际应用之前必须改进的化学问题。研究了氧和饮料风味成分存在下的金属螯合化学。
