Study On Effects Of Electrolyzed Oxidizing Water On Reducing Pathogens Contamination On Seafood And Processing Surrounding

Electrolyzed water is a new kind of functional water, generated through electrolysis from dilute salt solution in an electric field. In recent years, AEW has been regarded as a novel and effective sanitizer and used widely in medicine, agriculture, and food industry in order to improve safety for consumers. In this paper, the following aspects were reviewed and done some research in this thesis.Study on the inhibitory effects of electrolyzed oxidizing (EO) water made from water and seawater on food-borne pathogenic bacteria:The changes of parameters and the inhibitory effects of EO water was studied. It is suggested that both two kinds of EO water had effective effect on the food-borne pathogenic bacteria. The EO water made from 0.1%NaCl solution for 15min could kill Listeria monocytogenes (6.52Log1OCFU/mL) Vibrio parahaemolyticas (6.41 Log1OCFU/mL), Morganella morganii (6.03Log10CFU/mL) and Escherichia coli O157:H7. Salmonella enteritidis(6.15Log10CFU/mL)in 0.5min,2min, 5min and 10min. But the EO water made from seawater (salinity:2.76%) could made it in only 1min.Study on the of eliminating effects of electrolyzed oxidizing (EO) water by generating tap water and seawater:two kinds of EO water made from 0.1%NaC solution and the seawater (salinity:2.76%) were used to deal with the fish, shrimp and shellfish which were artificial contaminated with Salmonella enteritidis, Vibrio parahaemolyticas, Listeria monocytogenes, Morganella morganii, Escherichia coli O157:H7. The result suggested that both two kinds of EO water could inhibit 90% of the bacterium in the fish, shrimp and shellfish which contained 3.27Log10CFU/g,4.22Log10CFU/g,4.59Log10CFU/g respectively. And they can be applied in the production of aquatic products and improve the safety of them.Electrolyzed oxidizing (EO) water made from seawater was used to deal with the stainless steel sheet, ceramic tile, floor tile, mops and gloves which were artificial contaminated with bacteria to simulated the production environment. It was indicated in the experiment the EO water can kill all of the Salmonella enteritidis, Vibrio parahaemolyticas, Listeria monocytogenes, Morganella morganii on the surfaces of the stainless steel sheet, ceramic tile, floor tile, and Escherichia coli O157:H7 on the ceramic tile in 5 minutes which contained 7.12Log10CFU/mL,7.92LoglOCFU/mL,7.56Log10CFU/mL,9.11 Log 10CFU/mL and 7.99LoglOCFU/mL respectively. But the bacteria on the mops and gloves existed all the same after 5 minutes'treatment because of their coarse and bibulous texture, in which Salmonella enteritidis and Listeria monocytogenes were eliminated most and reduced 6.3 Log10CFU/mL and 6.52 LoglOCFU/mL respectively.
