Abstract
본 연구는 해발 780m 이상의 고랭지에서 재배된 사계성 딸기의 8개 품종에 대해서 품종 별 특성조사를 통해 이용목적에 따라 분류를 하고, 주요 수출품종인 'Charlotte'의 저장 및 유통 중 고품질 유지를 위해 전처리 기술 중 통풍식 예냉 처리를 실시하여 품질변화를 조사하였다. 가공용으로 이용되는 사계성 딸기의 품종별 경도는 1N 이상과 당도는 $6^{\circ}Brix$ 이상의 값이 요구되며 'Charlotte' 품종이 1.5N 이상으로 가장 경도가 높았다. 가용성 고형물 함량은 'Portola'와 'San Andreas' 품종을 제외한 6 종류 품종 모두 $6^{\circ}Brix$ 이상의 값을 나타냈으며 'Albion', 'Charlotte', 그리고 'Goha' 품종이 다른 품종에 비해 유의적 차이를 보이며 높게 나타났다. 색도지수인 hue angle과 chroma 값은 'Charlotte', 'Flamenco', 'GW-4', 그리고 'San Andreas' 품종에서는 높으며 좀더 선명한 붉은색을 띄었다. 저온 저장실험에 이용한 'Charlotte' 품종은 상온에 저장할 경우 저장 3일이 경과되면서 8% 이상의 중량 감모율을 보였다. 반면 $4^{\circ}C$와 $10^{\circ}C$의 저온저장은 저장 7일 동안 2%의 중량 감모율을 보였다. 저온저장 중에는 온도에 따른 유의적 차이는 없었으나 shelf-life 기간 동안에는 9%까지 무게손실이 증가되었으며 통풍식예냉 처리가 무예냉 처리에 비해서 중량 감모율이 적었다. 가용성 고형물의 함량은 모든 처리구에서 $6-8^{\circ}Brix$를 유지하는데, 예냉 처리에 따른 유의적 차이는 없었다. 곰팡이 발생은 저온 $4^{\circ}C$저장에서 예냉 유무에 관계없이 발생되지 않았으나 shelf-life 기간 동안에는 3일 경과 후부터 발생되었다. 과육의 색도는 저장기간 동안에는 온도처리 및 예냉 처리 유무에 따라서 일정한 경향이 없이 증감을 보이다가 상온으로 옮긴 shelf-life 기간 동안에는 $4^{\circ}C$ 저장된 과실의 경우 착색이 지연되었다. 수출 시 고랭지 사계성 딸기의 품질을 유지하기 위해서는 수확 후 $4^{\circ}C$ 이하의 온도조건을 유지하는 것이 중요하며 통풍식 예냉 효과는 미비하였다. This study was conducted to investigate the quality characteristics of eight everbearing strawberry cultivars and the effect of precooling treatment to maintain the quality during storage and shelf life of 'Charlotte'. Several quality parameters including firmness, soluble solids content (SSC), color, soluble sugars, and organic acids were evaluated. For Successful marketing everbearing strawberries required more than 1 N of firmness and $6^{\circ}Brix$ of SSC, respectively. 'Albion', 'Charlotte', and 'Goha' cultivars were higher in fruit SSC and 'Charlotte' cultivar was higher in fruit firmness among eight cultivars examined in this study. Fruit had more bright red color in 'Charlotte', 'Flamingo', 'GW-4', and 'San Andreas', which may reflect the consumer acceptance. Physicochemical characteristics of 'Charlotte' strawberry after with/without room precooling treatment were evaluated during storage at $4^{\circ}C$, $10^{\circ}C$, and $25^{\circ}C$ and additional 3 days at $25^{\circ}C$ for shelf-life. Weight loss increased about 8% in the fruits stored at $25^{\circ}C$ for 3 days, while in low temperature storage was about 2% for 7 days showing precooling was more effect on during shelf life periods rather than storage periods. Decay was not found during storage at $4^{\circ}C$ regardless of precooling treatment, but fungal growth was found in all the treatments after transferred to room temperature. Precooling treatment did not affect fruit color in shelf life period. For advanced marketing, everbearing strawberry should maintain in low temperature less than $4^{\circ}C$ to sustain quality, but the room precooling showed less significant effect to maintain quality on 'Charlotte' cultivar.
