Effect of cleaning solutions on the quality of fresh-cut Hami melons

In order to define the effects of different cleaning solutions on quality of fresh-cut Hami melon,the fresh-cut Hami melons were washed with tap water,acidic electrolyzed water(AEW),neutral electrolyzed water(NEW) and sodium hypochlorite,stored at 4℃ for 12 days,testing their bacterial residue,total soluble solids,titratable acid,vitamin C,malonaldehyde and sensory. Results reveled that washing with acidic electrolyzed water could effectively restrain the microbial growth,maintained content of total soluble solids,vitamin C and titratable acid,delayed the increasing of malonaldehyde content. However,although the effects of neutral electrolyzed water and sodium hypochlorite were better than those of the tap water,they were less efficient than those of acidic electrolyzed water. Taking into account of all these,acidic electrolyzed water washing could maintained good commodity value and prolong the shelf life of fresh-cut Hami melon.
