| The aim of this study was investigated long distance export condition of paprika from Korea to Canada, and evaluated the effect of non-perforated breathable films on the storability of paprika during MA storage in the simulated long distance export condition. The long distance export condition of paprika from Korea to Canada was $7{pm}1^{circ}C$ and RH 90% during shipping for 20 days, and then the temperature of that was increased to $13^{circ}C$ for 3 hours during transferring from refrigerated container to storage room in Canada, and decreased $3{sim}4^{circ}C$ for 3 days before distributing to local markets. The temperature and relative humidity of local markets was $16^{circ}C$ and 60%, respectively. The packing material treatments were non-packing, as control, perforated film (6 mm diameter hole, $18holes/m^2$), and 3 kind of laser treated non-perforated films (oxygen transmission rate was 5,000, 20,000 and 100,000 $cc/m^2{cdot}day{cdot}atm$). Under the simulated long distance export condition; $7^{circ}C$ and RH 90% for 15 days and then $20^{circ}C$ and RH 55% for 7 days, the fresh weight loss of paprika was less than 1% in 3 kind of laser treated non-perforated film treatments but was more than 4% in control and perforated film treatment that showed severe deterioration of visual quality after 20 days of storage. The atmosphere of paprika packages was changed 5% oxygen and 15% carbon dioxide in 5,000 $cc/m^2{cdot}day{cdot}atm$ treatment, and 16% oxygen and 4~5% carbon dioxide in 20,000 $cc/m^2{cdot}day{cdot}atm$ treatment during room temperature storage after cold storage for 15 days. A carbon dioxide concentration of these 2 treatments was exceeded the optimal MA and CA condition. There was no significant difference in ethylene concentration among 3 kind of laser treated non-perforated film treatments. A paprika packed with 100,000 $cc/m^2{cdot}day{cdot}atm$ non-perforated film showed the highest visual quality under the simulated long distance export condition. However, the firmness and soluble solids did not show any significant difference among 3 kind of laser treated non-perforated film treatments. Therefore, we may suggest that 100,000 $cc/m^2{cdot}day{cdot}atm$ laser treated non-perforated film was the proper film for MAP of paprika under long distance export condition that was $7{pm}1^{circ}C$ and RH 90% for 15 days, and then $20^{circ}C$ and RH 55% for 7 days. |
