Abstract: The aim of the article was to study the water-saving ability of acid electrolyzed water in fresh-cut carrots washing procedure. The bacteriostatic effect of the acid electrolyzed water on fresh-cut carrots was investigated in the condition of different water consuming proportions and multiple washing which compared with commercial sanitizer (sodium hypochlorite) . Meanwhile, the phy-chemical properties of washing water were measured. Results indicated that acid electrolyzed water showed significant bacteriostatic effect in washing fresh-cut carrots under the condition of low water consuming proportion. The recycling use of acid electrolyzed water could maintain a significant bacteriostatic effect and prevent cross contamination in washing water. Due to the water-saving advantages, acid electrolyzed water could be used to improve the application in fresh-cut vegetables in future.
