Alkaline Electrolyzed Water

Home processing can reduce pesticide residues in agricultural products, and the common forms of treatment include washing, peeling, blanching, and cooking. In this study, the removal effects of tap water, micron calcium solution, alkaline electrolyzed water (AlEW), ozone water, active oxygen, and sodium bicarbonate on 10 typical pesticide residues in kumquat, cucumber, and spinach were investigated. The residue magnitudes were determined by chromatography–tandem mass spectrometry (GC-MS/MS, LC-MS/MS), combined with the QuEChERS pretreatment method. The model tests showed that the results of soaking and greenhouse were close. The removal effects of pesticide residues in kumquat and cucumber washing by alkaline electrolyzed water with a high pH value, micron calcium, and active oxygen solution were better than other washing solutions. The sodium bicarbonate solution, ozone water, and active oxygen solution were more effective in reducing pesticide residues in spinach than others. Active oxygen solution showed a better removal efficiency for the 10 pesticides than other treatments because of its alkalinity and oxidizability. Among the ten pesticides, pyrethroid pesticides had a higher removal rate. Additionally, chlorpyrifos were the most difficult to remove. For the majority of pesticides, the pesticide residue magnitudes showed a gradual reduction when increasing the washing time. The results indicated that alkaline solutions were effective for the reduction of pesticide residues when the washing time was longer than 15 min.

Fresh Cut

The efficacy of slightly acidic electrolyzed water (SAEW, 20 mg/l of available chlorine) and sodium hypochlorite solution (NaClO, 120 mg/l of available chlorine) used as potential sanitizers for fresh-cut cucumbers was evaluated. SAEW with a near-neutral pH value (5.0 to 6.5) and lower available chlorine concentration (ACC) had an equivalent or higher efficiency to reduce microbial counts on the cucumbers compared to NaClO solution. A 5-minute treatment of SAEW and NaClO solution significantly reduced the indigenous aerobic bacteria on cucumbers by 1.62 and 1.51 log10 CFU/g, and molds and yeasts by 1.35 and 1.12 log10 CFU/g, respectively (P < 0.05). The reduction of microbial counts on cucumbers by tap water was markedly less than that by SAEW and NaClO solution (P < 0.05). Results indicate that SAEW provides an alternative technique for sanitization of fresh-cut vegetables with environmentally friendly broad spectrum microbial decontamination.

The purpose of this study is to develop the environment-friendly coolant. Cylindrical plunge grinding tests are carried out using alkaline electrolyzed water, high-frequency reduced water and alkali-reduced water as coolant. Most effective coolant is brought out in comparison with surface roughness, grinding force and workpiece surface temperature. Moreover, elemental analyses and measurements of contact angle of treated water are carried out in order to clarify the effect on grinding performance. Furthermore, elemental analyses and observation of evaporation residues in treated water are also carried out. As a result, grinding performance using alkali-reduced water is better than that using alkaline electrolyzed water or high-frequency reduced water.

Electrode Plate

The lab-scale electrolytic cell was designed to produce acidic and alkaline electrolyzed water for cleaning study. Electrolyzed water (EW) was produced by electrolysis of a dilute sodium chloride solution. The generation of free chlorine, pH and oxidation-reduction potential from the electrolysis process by the electrolytic cell were far from the expected value. Thus, the lab-scale electrolytic cell was revamped by using the acrylic slot to hold the electrode plate and a membrane holder without metal screws. This revamp work is to reduce the resistance for current flow with the aim to increase the value of chemical properties (pH, oxidation-reduction potential, free chlorine) for acidic and alkaline electrolyzed water. Findings have shown that the current was increased from 0.013A to 2.5A after the revamp process. As a result of the revamp, the value of pH, oxidationreduction potential and free chlorine for acidic electrolyzed water was increased by 1.7 times, 2.7 times, and 20 times higher than previous results respectively. While for alkaline electrolyzed water, the value of pH and oxidation-reduction potential was increased by 1.4 times and 6.2 times higher than previous results respectively.
