Selection of Non-Perforated Breathable Film to Enhance Storability of Cherry Tomato for Modified Atmosphere Storage at Different Temperatures

초록

This study was conducted to find out the appropriate packaging materials to extend the storability and maintainthe quality of cherry tomato for modified atmosphere (MA) storage. Tomatoes were grown by hydroponic at a plastichouse in Gangwon Province. Light red maturity stage tomatoes were harvested and packed with MA condition(10,000; 20,000; 40,000; 60,000; 80,000; and 100,000cc/m2.day.atm O2 permeability film) and perforated film to store at5oC, 11oC and 24oC. The fresh weight loss was less than 0.6% in all non-perforated breathable films at 5oC, 11oC, and24oC, but perforated film had less than 2.93% at 5oC, 13.29% at 11oC and 27.24% at 24oC. The 20,000cc at 5oC and11oC, and the 40,000cc film at 24oC balanced optimum carbon dioxide and oxygen concentration in the package tomaintain quality. The 10,000cc film was appeared the significantly highest ethylene concentration at 5oC, 11oC, and24oC, this film had the lowest O2 permeability. Visual quality, firmness, and soluble solids were maintained in 20,000ccfilms both at 5oC and 11oC, the 40,000cc film at 24oC. There was no any trend in titratable acidity and vitamin C contentof treated packed film types and temperatures at cherry tomatoes packages. Therefore, the appropriate MA conditionfor 5oC and 11oC is 20,000cc/m2.day.atm O2 permeability film; for 24oC it is 40,000cc/m2.day.atm O2 permeabilityfilm because those films extended the storability through the firmness, soluble solids as well as visual quality.
