The Effect of Functional MA Film Packaging on Storage of Mature-Red Tomato

The mature-red tomato fruits (cv. Pinky world) were packaged with functional modified atmosphere (MA) film (0.03, 0.06 mm) and stored at 0, 5, $15^{\circ}C$. The results showed that the concentrations of $CO_2$ and $O_2$ inside MA package were about $4.21{\sim}8.17%$ and $9.78{\sim}14.45%$ under steady state during storage 29 days at 0, $5^{\circ}C$, respectively. The MA packaging(MAP) suppressed the fruits softening and the color change. The minimum lycopene content and maximum firmness were separately observed in fruits packaged with MA film (0.03 mm) at $5^{\circ}C$ storage and film(0.06 mm) at $0^{\circ}C$, which the lycopene content 6.08 mg/100 g, and firmness was 0.49 Kgf at 29 th day storage. The optimal conditions to keep high quality of tomato fruits were obtained by MAP during storage at $0^{\circ}C$ for 29 days, independently of the film thickness, in which the adequate gas composition was $CO_2$ at $4.2%{\sim}5.6%$, $O_2$ at $14.3%{\sim}14.5%$, respectively.

토마토(Pinky 종)를 기능성 MA필름(두께 0.03, 0.06mm)으로 포장하여 0, 5, $15^{\circ}C$에 저장하면서 품질 변화를 조사하였다. 저장 29일에 MA포장재 내의 $CO_2$, $O_2$농도는 각각 $4.21{\sim}8.17%$, $9.78{\sim}14.45%$였고, 전반적으로 MA 포장구에서 연화와 색택의 변화가 억제되었다. 저장 29일에 MA포장(0.03두께)을 한 후 $5^{\circ}C$에 저장한 토마토의 경도(0.49 kgf)가 가장 높았고, MA 포장(0.06두께)을 한 후 $0^{\circ}C$에 저장한 토마토가 최소 라이코펜 함량(6.08mg/100g)을 보였다. 토마토의 품질 유지를 위한 최적 조건은 MA 장을 하여 $0^{\circ}C$에 저장하는 것이 바람직한 것으로 나타났으며 필름 두께간에는 유의적인 차이가 나타나지 않았다. 또한 MA 포장재 내의 최적 가스 조성은 $CO_2$는 $4.2%{\sim}5.6%$, $O_2$는 $14.3%{\sim}14.5%$로 나타났다.
