鹼性電解水制酸、抗氧化及抗突變性之研究

由於水質污染情形日益嚴重，導致飲用水的水源處理需經多層過濾及各種化學試劑進行殺菌，如氯、氟、臭氧等。因此市面上出現各式淨水器，如純水機、逆滲透機（RO）等。近日更出現標榜能製造出機能水（如磁化水、電解水、能量水）等機種。本研究以市售家用電解水機所獲之鹼性電解水，探討水質特性與功能性。 自來水經家用電解水機器後，水體的pH值與氧化還原電位（ORP）會因電壓之改變而發生顯著之變化。本試驗採用之鹼性電解水pH值與ORP分別有8.7（-84mV）、9.1（-110mV）、9.3（-121mV）及9.5（-130mV）等四種。由試驗結果可知：在模擬生理性動態胃模型中發現，各種電解程度之鹼性電解水，並不會大幅度改變胃部pH值，同時也不具有緩衝及制酸效用。在抗氧化方面，鹼性電解水之抗氧化力與清除過氧化氫及氫氧自由基的能力皆會隨著劑量的增加而提高。此外，鹼性電解水可有效降低誘突變劑（N-methyl-N’-nitro-N- nitroso-guanidine；MNNG、t-BuOOH及2-amino-3-methylimidazo-〔4,5-f〕-quinoline ；IQ）對Salmonella typhimurium TA98、TA100、TA102之誘突變性，無論有無S9的存在下其抑制率皆可達30%-50%左右。

Physical or chemical treatments （e.g. Cl2, F, O3）were used to clarify drinking water because of water pollution. Therefore, many water treating machines were produced, for example pure water machine and revere-osmosis machine（RO）. Recently, machines for functional water（e.g. magnetizations water, electrolyzed water were developed）. The purpose of this study was to evaluate the properties and functions of alkaline electrolyzed water obtained for home used machine. Four alkaline electrolyzed water sample were used in this study. Then pH value and oxidantion-reduction potential（ORP）were quite different, such as 8.7（-84 mV）, 9.1（-110 mV）, 9.3（-121 mV）, 9.5（-130 mV）. Results revealed that the alkaline electrolyzed water samples did not change stomach pH value and had no buffer and antacid function in the artificial stomach model. The antioxidant activity and free radical scavenging efficiency of alkaline electrolyzed water showed dose-dependent and increased with the ORP. Further more, alkaline electrolyzed water also can reduced 30-50% of the function of mutagenic agents（such as N-methyl-N’-nitro-N-nitroso-guanidine（MNNG）, t-BuOOH, 2-amino-3-methylimidazo-〔4,5-f〕-quinoline （IQ））toward Salmonella typhimurium TA98, TA100 and TA102.
