- Abstract:
- With fresh-cut broccoli as test materials，control function of ozone water of different concentrations and treatment time on the surface of moulds and yeasts，bacteria，coliform bacteria and other microbial contamination were studied.The results showed that ozone water could effectively reduce the pollution of fresh-cut broccoli caused by microorganisms，made the count of fresh-cut broccoli mold and yeast reduced one order of magnitude，the total number of bacteria reduced two to three orders of magnitude.All the number of storage 8 days of coliform what were processed by 2.0 mg/L and 4.0 mg/L of ozone water conform to standards of cooking food.The method achieved the purpose what could extend shelf life，ensure food safety，and increase the value of the goods.
