미세천공 포장재가 신선절단 사과의 품질유지에 미치는 영향을 확인하기 위하여, 원형사과(Malus domestica Borkh. cv. Red Delicious)를 제심, 절단한 후 레이저로 미세공을 하나 천공한 것과 천공하지 않은 polyolefin 필름으로 밀봉 포장하고 에서 3주간 저장하면서 이화학적 품질 특성들의 변화를 조사하였다. 절단사과의 과육경도는 저장 1주 후부터 천공포장구에서 유의적으로 높은 값은 보였고, 가용성 고형분 함량은 저장

The effect of microperforated packaging films on fresh-cut apples was studied Apples (Malus domestica Borkh. cv. Red Delicious) were cored and cut, packaged in laser microperforated film or non-microperforated polyolefin film, and stored for 3 weeks at 4C. The flesh firmness of apples packaged in microperforated film during the storage period was significantly higher than that of apples packaged in non-microperforated film, and the level of soluble solids was also higher. The browning index, titratable acidity, pH, acetaldehyde and ethanol levels were not affected by microperforation. These results show that microperforated films could be used for retention of flesh firmness in fresh-cut apples.
