수도수(TW), 0.85% 식염수(0.85% NaCl) 및 0.5% Sodium metabisulfite(0.5% SMS)를 대조구로 하고 강산성 전기분해수(SAEW ; Strong Acidic Electrolyzed Water, pH 2.53, ORP 1,088 mV, HClO 91.25 ppm)와 약알칼리 전기분해수 (LAEW ; Law Altaline Electrolyzed Water, pH 8.756, ORP 534 mV, HClO 105
The efficacy of strong acidic electrolyzed water (SAEW) at pH 2.53, with ORP of 1,088 mV and HClO concentration of 91.25 ppm, and low alkaline electrolyzed water (LAEW) at pH 8.756, with ORP of 534 mV and HClO concentration of 105.70 ppm, as storing liquids for peeled potato and sweet potato was evaluated in this study. During storage at , total phenolic contents and PPO activities of peeled potato and sweet potato stored in SAEW and LAEW were lower than those of control samples stored in tap racer (TW) with 0.85% (w/v) NaCl and 0.5% (w/v) sodium metabisulfite (SMS). Increment in color differences and decreases in hardness of peeled potato and sweet potato stored in SAEW and LAEW were lower than those of controls. Also, SAEW and LAEW inhibited growth of microorganisms for at least 3-6 days of storage. The sensory characteristics of peeled potato and sweet potato stored in LAEW were best during the first half of the storage period, compared to samples preserved by other methods.
