Abstract

Quality deterioration during storage such as weight and fruit firmness loss after harvest is one of the main problems in summer cultivation of mini paprika. Objective of this study was to determine appropriate storage temperature and duration in the mini paprika('Hivita Yellow' and 'Hivita Red'). More fruit firmness loss during storage was observed at higher storage temperature. Fruit firmness of 'Hivita Yellow' at $20^{\circ}C$ was $99.6g/cm^2$ after a 5-day storage whereas that decreased by $73.0g/cm^2$ after a 40-day storage. Storing 'Hivita Yellow' at $8^{\circ}C$ showed the lowest fruit firmness loss with 109.7 and $92.7g/cm^2$ after a 5-day and a 40-day storage, respectively. In both cultivars, soluble solids content of fruits was higher at $20^{\circ}C$ than at 4, 8 and $12^{\circ}C$. Higher temperature triggered more water loss of the fruits with more occurrence of soft rot and shriveling symptoms. The changes in electrolyte conductivity of fruits during storage was higher in the fruits at lower temperature. Fruit stored at $20^{\circ}C$ showed the highest respiration(more $CO_2$ and less $O_2$) during storage than fruits at the other storage temperatures.

미니파프리카의 저장 후 수분손실과 경도변화로 인한 상품과실의 감소는 여름재배에서 주요한 문제점 중의 하나이다. 본 연구의 목적은 미니파프리카('하이비타 엘로우'와 '하이비타 레드')의 저장기간에 따른 적정 저장온도를 구명하는데 있다. 미니파프리카의 저장온도 시험에서 경도변화는 $8^{\circ}C$에서 저장한 것 보다 $20^{\circ}C$에 저장한 것이 변화가 높은 것으로 나타났다. 하이비타 엘로우의 경우 5일 저장 후 $20^{\circ}C$에서 경도가 $99.6g/cm^2$이었으며, 40일 저장은 $73.0g/cm^2$로 5일 처리와 비교할 때 $26.6g/cm^2$의 차이가 있는데 반하여 $8^{\circ}C$ 저장은 $109.7g/cm^2$에서 $92.7g/cm^2$으로 $17.0g/cm^2$ 의 차이가 나타나 $8^{\circ}C$에서 경도 감소가 적은 것으로 나타났다. 가용성 당 함량은 두 품종 모두 4, 8, $12^{\circ}C$ 보다 $20^{\circ}C$에서 높은 경향을 보였으며, 과실의 부패와 수분손실에 의한 과피주름짐 현상도 $20^{\circ}C$에서 높았다. 공기조성 변화는 $20^{\circ}C$ 처리구에서 $CO_2$ 함량이 높고 $O_2$ 함량이 낮았다.
