This study was conducted to define the optimal Lycium chinense miller washing method for developing the Lycium chinense cleaner and we analyzed the Lycium chinense miller washing characteristics for removing pesticides and microorganism according to washing methods; habitual washing method, air bubble washing method and nozzle spray washing method. The results were summarized as follows; 1. In case of measuring physical properties according to the varieties, maximum yield strength of Hokwang was 2.562 kgf, minimum yield strength of Hokwang was 0.269 kgf and average yield strength was about 1 kgf. 2. In case of measuring change of bacteria according to washing methods, the number of bacteria of non-washing method was more than the number of bacteria of habitual washing method or mechanical washing method and the number of nozzle spray washing method was least. 3. Ahjoksiseuteurobin of 0.218 ppm was detected in the untreated sample, 0.051 ppm was detected in the habitual washing method, 0.047 ppm was detected in the air bubble washing method and 0.034 ppm was detected in nozzle spray washing method. Every amount detected were less than 2 ppm that is reference value and the detected amount was least in case of nozzle spay cleaning method. Cypermethrin of 0.772 ppm was detected in the non-cleaned sample, 0.089ppm was detected in habitual washing method, 0.26 ppm was detected in the air bubble washing method and 0.292 ppm was detected in the nozzle spray washing method. Every detected amount of Cypermethrin were less than 5 ppm that is reference value and the detected amount was least in case of habitual washing method.

This study was performed in order to determine whether a combined treatment of ultrasound and sodium hypochlorite (NaOCl) is more effective than individual treatment on reducing Listeria monocytogenes ATCC19118 on stainless steel and iceberg lettuce. The bactericidal effect of ultrasound and NaOCl was investigated in tryptic soy broth (TSB), on stainless steel and iceberg lettuce. Various concentrations of NaOCl (50, 100, 150, and 200 ppm) were tested along with various ultrasound treatment times (5, 20, 40, 60, 80, and 100 min). The combined treatment of ultrasound and NaOCl resulted in greater bacterial reductions than either treatment alone, without causing any significant changes in lettuce texture. The synergistic values of combined ultrasound and NaOCl treatments in TSB, on stainless steel, and on iceberg lettuce were 0.01-0.99 log10 colony-forming units (CFU)/mL, 0.01-0.62 log 10 CFU/g, and 0.12-1.66 log10 CFU/g, respectively. These results suggest that the combination of ultrasound and NaOCl was more effective than each treatment against Listeria monocytogenes, and that this combination can effectively sanitize fresh products such as iceberg lettuce.
