ALCOHOLIC BEVERAGE WITH ANTIOXIDATIVE FUNCTION, LOW-TEMPERATURE REMOVING METHOD OF ACETALDEHYDE OF ALCOHOLIC BEVERAGE, REDUCTIVE FERMENTATION METHOD AND OXIDATIVE-REDUCTIVE BREWING METHOD AND APPARATUS THEREFOR

摘要

An alcoholic beverage containing ultrafine bubbles of hydrogen with an antioxidative function is provided that is produced by a reductive fermentation technique of alcohol and contains only a small amount of acetaldehyde. A method and an apparatus of oxidative-reductive fermentation of varieties of alcoholic beverages are provided based on facilitation of proliferation of microorganisms under an oxidative condition and a reductive fermentation technique. The reductive fermentation technique suppresses oxidative degradation of generated pyruvic acid, activate alcohol dehydrogenase, and facilitates production of alcohol from acetaldehyde which is an intermediate product, and a gas exchanging function of the ultrafine bubbles of hydrogen decreases acetaldehyde that remains in a period of alcohol fermentation. The technique facilitates fermentation, increases alcohol yield, decreases acetaldehyde content, and enhances fresh savor, mellow taste and an antioxidative function of an alcoholic beverage.
