“…These results are similar to those obtained by Rahman et al (2011), who reported that 100 ppm chlorine treatment for 3 min showed superior reduction of TPC than 1 min in carrot samples; however, 5 min exposure was not significantly better. Likewise, 100 ppm NaClO treatment for 3 min reduced microbial counts in cabbage and a non-significant difference was observed for 10 min exposure (Rahman et al, 2010).…”

“…However, the combination of EW with chitosan showed better antimicrobial efficacy than the combination of EW with CMC. Rahman et al (2011) investigated about the combination treatment of alkaline EW and citric acid with mild heat to ensure microbial safety and sensory quality of shredded carrots. The results showed that the dipping in sanitiser solution for 3 min at 50 C is effective to reduce the microbial count but did not influence the tissue, pH and surface colour of shredded carrots, compared to the untreated control.…”

Food safety is a priority for the food industry and to achieve this result a correct plant sanitation programme is of the utmost importance. Among various disinfection techniques, an emerging one is represented by the use of electrolysed water (EW) as the disinfecting agent. The use of EW is compliant with the desire to find alternatives to chlorination and heat treatments, representing a green cleaning alternative to toxic disinfectants. EW is an activated liquid, obtained by passing a diluted saline solution (NaCl, KCl or MgCl 2 ) through an electrolytic cell, thus causing the production from the anode side of electrolysed oxidising water, containing high dissolved oxygen, free chlorine and characterised by a low pH (2.3-2.7) and a high oxidation-reduction potential (ORP > 1,000 mV). At the same time from the cathode side electrolysed reduced water is produced, with high pH (10.0-11.5), high dissolved hydrogen and low ORP (À800 to À900 mV). Unlike other chemical disinfectants, EW is not harmful for skin and mucous membranes and is quite easy to handle. Furthermore, the use of EW is relatively inexpensive and, above all, is a sustainable technique. Currently used sanitisers (e.g. glutaraldehyde, formaldehyde, etc.) are effective, but their adverse effects on the environment are well known. Differently from these chemicals, the use of EW has a reduced impact on the environment and because of its properties, it may find several applications in the food industry. In this work, the characteristics and some EW applications as sustainable sanitation technique applied in the food industry are reported and discussed.

“…Acid electrolyzed water AcEW and alkaline electrolyzed water AlEW are produced by the electrolysis of dilute sodium chloride NaCl solution on the anode side and the cathode side of an instrument, respectively, where the anode and cathode are separated by an ionpermeable diaphragm. AcEW is commonly used in the agricultural field as a disinfectant in farm and food hygiene Guentzel et al, 2008;Lu et al, 2010;Rahman et al, 2011 . It is also widely used for the disinfection of medical instruments such as dialyzers Tanaka et al, 2000, endoscopes Lee et al, 2004, and dentures Nagamatsu et al, 2001 because of its potent antimicrobial potential Nisola et al, 2011;Feliciano et al, 2012 .…”

There have been attempts to apply AlEW as a supplementary agent for disinfection because of its high potential for decontamination Kim et al, 2005;Park et al, 2009;Rahman et al 2011 . In dentistry, several studies have applied AcEW to oral hygiene Tanaka et al, 1999;Shiba et al, 2000;Qing et al, 2006 , and AcEW was proven effective for the treatment of oral candidiasis Tanaka et al, 1999 .…”

Bactericidal Action of Photodynamic Antimicrobial Chemotherapy (PACT) with Photosensitizers Used as Plaque-Disclosing Agents against Experimental Biofilm

et al. 2016

Our previous study revealed that the photo-irradiation of rose bengal, erythrosine, and phloxine, xanthene photosensitizers, used as dental plaque disclosing agents, could exert bactericidal action on planktonic Streptococcus mutans via the singlet oxygen. In the present study, the photo-irradiation induced bactericidal activity of the three xanthene compounds against the experimental biofilm of S. mutans was investigated in combination with acid electrolyzed water AcEW and alkaline electrolyzed water AlEW . As a result, only the photo-irradiated rose bengal in AlEW showed prominent bactericidal activity with a >3-log reduction of the viable bacterial count. Since our previous study showed that the affinity of rose bengal to bacterial cells was superior to that of erythrosine and phloxine, it was speculated that AlEW damaged the extracellular matrix of the experimental biofilm, which would let the rose bengal easily be bound to the bacterial cells. From these results, it is strongly suggested that rose bengal is a suitable photosensitizer for use as a plaque disclosing agent in photodynamic antimicrobial chemotherapy to treat dental plaque.
