Abstract

Edible flowers are harvested at the full bloom stage and distributed without floral stems, which makes the flower quality deteriorated quickly. Thereby, this study was carried out for selection of effective storage film at room temperature during the distribution of edible flowers. Edible flowers, snapdragon (Antirrhinum majus), pot-marigold (Calendula officinalis), sweet violet (Viola odorata), clove pink (Dianthus caryophyllus), wild pansy (Viola tricolor), nasturtium (Tropaeolum majus) were used to select the effective storage film at room temperature during the distribution, polyethylene (PE) film (0.03 mm), polypropylene (PP) film (0.03 mm). PP (LF10) film packing was very effective for longer shelf life for sweet violet, clove pink, and wild pansy. But, there were little different for pot-marigold and nasturtium. Wilting at sweet violet, clove pink, and wild pansy, and petal-soft rot and color break at nasturtium were appeared. Browning and rot were appeared to snapdragon.

식용꽃은 일반적으로 개화된 상태에서 수확, 줄기가 없는 상태에서 유통되므로 저장성이 급격히 저하되는 것이 단점이다. 이에 본 연구는 여러 종류의 포장 필름 중 식용꽃의 상온유통을 위한 효과적인 포장재를 선발하기 위하여 실시하였다. 식용꽃 재료로는 꾸준한 수요로 연중생산 되고 있는 금어초, 금잔화, 비올라, 패랭이, 팬지, 한련화 등 총 6종으로 실시하였다. 유통 시 적용할 포장 필름을 선발하기 위하여 0.03mm 두께의 polyethlene (PE) film와 polypropylene (PP) film을 대조구로 하였으며 필름 표면의 미세한 천공을 통해 산소투과도 (OTR-Oxygen Transmission Rate)를 조절할 수 있는 6가지 종류의 필름인 PE 0.03 mm (LF10, LF20, LF30), PP 0.0 3mm (LF10, LF20, LF30) 등을 이용하였다. 식용꽃의 상온 유통시 금잔화, 한련화는 필름별 차이가 없었으며, 비올라, 패랭이, 팬지는 PP (LF10)필름이 효과적인 것으로 나타났다. 비올라, 패랭이, 팬지는 꽃잎이 바깥쪽부터 말리기 시작하면서 노화 증상이 나타났고, 한련화는 꽃잎 무름과 변색, 금어초는 갈색 점이 나타나면서 부패증상이 나타나는 등 식용꽃 종류별로 노화 유형이 뚜렷하게 구분되었다.
