The goal of this study was to characterize the quality and physiological functionality of some traditional rice wines in Chungnam province, Korea. Non-sterilized and commercial sterilized traditional rice wines from five traditional rice wine factories of Chungnam province were collected and investigated for nutritional components, noxious compounds and physiological functionality. Ethanol content ranged from 16.1-18.3% and pH ranged from 3.27-4.76, and they also contained 0.15% to 0.55% of total acid. All traditional rice wines contained 10.15-139.9 mg% of amino nitrogen and 2.5-25.7% of total sugar. Among organic acids, lactic acid was contained 7.4-29.6 mg%, and succinic acid and propionic acid was also contained 0.2-2.7 mg% and 0.7-8.3 mg%, respectively. Antihypertensive angiotensin I-converting enzyme inhibitory activity were showed 37.0-86.0% in all rice wines, however, fibrinolytic activity, antioxidant activity, SOD-like activity and acetylcholinesterase inhibitory activity were low or not detected.
