Abstract

To investigate the effects of the improvement of postharvest quality on fresh tomato, antimicrobial microperforated (AMP) films were prepared and their antimicrobial abilities were observed. AMP films were made by coating different types of natural antimicrobial agents such as cinnamon, clove, and clary sage essential oils into microperforated (MP) films. Cinnamon essential oil of 10% (v/v) has proven to be very effective as inhibitor of the mold growth on tomato, compared to the clove and clary sage essential oils. Quality changes of fresh tomatoes packed using the natural AMP films (AMP10 and AMP30) and MP films (MP10 and MP30) during storage were evaluated. Total microbial growth, weight loss, firmness, lycopene content, and decay rate as the major quality parameters were monitored over 9 days at $15^{\circ}C$. The oxygen transmission rates and mechanical properties between the natural AMP and MP films were also compared. There was no significant difference in change of oxygen transmission rate, tensile strength and elongation between the AMP and MP films. For storage studies, the freshness of tomato packaged in AMP30 film was higher than that in OPP film (the control), MP10, MP30, and AMP10 films. Especially, AMP30 film exhibited high efficiency compared to the control for tomato decay during storage periods. Based on the results, the microperforation and antimicrobial properties of the packaged films may significantly affect the maintenance of an optimum gas composition within the package atmosphere for increasing the storage life and quality of produce. They were also effective on the inhibition of microbial growth by controlled release of antimicrobial agent at an appropriate rate from the package into the tomato. Natural antimicrobial agent coating microperforated films could use potential functional package as a method of extending the freshness of postharvest tomato for storage.

본 연구는 수확 후 송이토마토의 품질 유지를 확보하기 위하여 포장 내부의 적정 산소와 이산화탄소 농도를 유지하고 천연항균물질을 적용하여 과채류의 호흡장해 및 부패 미생물의 발생을 억제하는 효과를 얻고자 하였다. 이를 위하여 천연항균물질이 코팅된 미세천공필름으로 포장한 송이 토마토의 저장 중 품질변화 효과를 관찰하였다. 송이토마토 곰팡이균 발생 억제를 위한 계피유, 클로브유, 및 클라리 세이지유의 천연항균물질들의 항균성 평가는 계피유에서 가장 높은 항균성을 보여주었다. 천연항균물질이 코팅된 미세 천공필름의 산소 투과도는 무처리 미세천공필름과 비교하였을 때 유의적인 차이는 없었으며, 각 포장필름의 물리적 특성 평가에서 항균물질 코팅된 필름의 인장강도와 신장률 값은 무처리 및 미세천공필름 값과 비교하여 유사한 값을 나타냈다. 10% 계피유가 코팅된 항균미세천공필름(AMP30), 무처리 미세천공필름(MP10, MP30), 그리고 일반 OPP필름으로 포장한 송이토마토의 포장재 내 기체조성 평가는 MP30과 AMP30필름에서 송이토마토의 적정 선도유지를 위한 기체조성 조건인 각각 5.0와 4.8% 산소 농도 그리고 4.3와 4.4% 이산화탄소 농도를 유지하는 것을 관찰할 수 있었다. 또한 $15^{\circ}C$의 저장성 평가 실험에서 항균미세천공필름(AMP30)이 다른 필름포장재보다 송이토마토의 경도, 중량 감소, 그리고 부패 현상을 억제하는데 효과적인 결과를 나타냈다. 따라서 계피유가 처리된 천연항균 특성을 가진 미세천공필름 적용은 신선 송이토마토의 품질 개선에 효과적인 방법인 것으로 판단된다.
