Abstract

The effect of packaging material in enhancing the shelf life and maintaining the postharvest quality of endive (Cichorium endivia L.) was studied. Endive were packed in three packaging materials: paper box (control); paper box with endive wrapped in high density polyethylene (HDPE) film; and plastic box container covered with high density polyethylene (HDPE) film. The quality characteristics, such as fresh weight loss, soil plant analysis development (SPAD) value, and appearance of endive were investigated during 20 days of storage at $2^{\circ}C$. The endive wrapped with HDPE film inside the paper box showed the lowest weight loss, highest SPAD value and the best appearance compared to those wrapped in other packaging types during storage. The results indicate that the marketability of endive can be optimized with proper packaging and storage.

본 연구에서는 엔다이브의 선도유지를 위하여 수확 후 포장방법을 달리한 후 저장하며 품질변화를 조사하였다. 엔다이브를 수확한 후 종이박스, 종이박스에 HDPE 필름 속포장, 농산물유통상자(P박스)에 HDPE 필름 등으로 포장한 후 $2^{\circ}C$에 저장하며 저장 중 중량감모, 수분함량, 엽록소 함량, 경도, 표면색도 및 신선도 등을 평가하였다. 저장기간이 경과함에 따라 관행적 방법인 종이박스로 포장한 엔다이브의 중량감모율이 다른 방법으로 포장한 처리구보다 가장 높았고, 수분함량이 가장 낮았다. SPAD 지수는 종이박스에 HDPE 필름으로 속포장한 엔다이브가 다른 포장방법에 비하여 높은 값을 유지하였으며 저장 중 경도 감소폭이 낮았다. 종이박스로 포장한 엔다이브는 저장 중 황화현상이 많이 일어났으며 전체 색 변화가 가장 심했고, 종이박스에 HDPE 필름으로 속포장한 엔다이브의 색변화가 가장 적었다. 따라서 엔다이브의 수확 후 선도유지를 위하여 종이박스에 HDPE 필름으로 속포장하는 것이 품질유지에 효과적인 방법이라 판단된다.
