NOVELTY - A water preparation system comprises an electrolysis device in fluid communication with a water preconditioning system and configured to perform electrolysis on the preconditioned water, where the system outputs alkaline water and/or acidic water with a stable negative oxidation reduction potential.    USE - The system is used for preparing water with a stable negative oxidation reduction potential, useful as fermentation liquor of all kinds of fermentation processes, e.g. drug production or food processing by microorganisms. The water is also used in increasing the oxygen content of blood and tissues, oxygenation of wounds to increase the rate of healing and to reduce infections, oxygenated organ transplant storage media, tumor oxygenation for radiation therapy and chemotherapy, lung bypass by oxygenated liquids in case of pulmonary deficiencies, carbon monoxide poisoning, mouthwashes, dentifrices, topical including cosmetic treatment media, contact lens treating solutions, and cell level therapeutic applications. It is used as solvents for physiological saline isotonic solutions. It is used in a beauty product, a non-drug product, skin-care product, makeup product, hair care product, fragrance, body care product, and oral care product. It can also be used in agricultural food, canned good, instant food, livestock food, fishery food, and fermented food. It is used in beverages, e.g. alcoholic beverages such as brewed sake, synthetic sake, shochu, sweet sake, beer, whisky, liquor, fruit liquor, and favorite soft beverages or refreshing beverages such as fruit juice.    ADVANTAGE - The water improves a quality of food and beverage and has beneficial effects that can be sustained over a long term.    DETAILED DESCRIPTION - A water preparation system (103) comprises;    (1) a water preconditioning system to receive water (10, 20) from a water source and output water preconditioned for electrolysis;    (2) an electrolysis device in fluid communication with the water preconditioning system and configured to perform electrolysis on the preconditioned water, where the system outputs alkaline water and/or acidic water with a stable negative oxidation reduction potential (ORP);    (3) an oxygen generator for generating oxygen;    (4) a combining unit coupled to the oxygen generator for combining the oxygen with the negative ORP water; and    (5) a diffusion chamber coupled to the combining unit for receiving the combined negative ORP water and oxygen and manipulating them into a vortex to cause the oxygen to diffuse into the negative ORP water.
