Abstract

This study was conducted to investigate the quality characteristics of eight Kimchi cabbage cultivars and the effect of cold storage on the quality of two kinds of cabbage cultivars, such as 'CR-Nongshim', and 'Ryouckgwang'. Early planted and harvested cultivars at July showed that fresh weight was lower than late harvested cultivars at September, because early harvesting time of July was heavy rainy season at highlands of Gangwon province. The firmness was more than 10 N for all cultivars and 'Cheongock', 'Sanjanggoon', and 'Ryouckgwang' cultivars had high value of firmness among them. No differences among the cultivars were found in appearance, freshness, and texture evaluations at harvest. Sweetness and bitterness had statistical differences and showed high value in 'Ryouckgwang' and in 'CR-Nongshim' and 'Sooho'. Two Kimchi cabbage cultivars such as 'CR-Nongshim' and 'Ryouckgwang' were stored at $0^{\circ}C$, $2^{\circ}C$, $5^{\circ}C$, and room temperature ($25^{\circ}C$) with more than 90% RH. Significant difference was found in weight loss during room and low temperature storage. In general, weight loss of the Kimchi cabbages at room temperature was significantly increased by 15% within 3 days, whereas it was delayed at low temperature until 3 weeks on all Kimchi cabbage cultivars. Firmness of 'CR-Nongshim' was higher than 'Ryouckgwang' but there was no difference within low storage temperatures. Appearance among the sensory factors was a critical indicator to estimate storage periods. On the point of appearance, storage period at $0^{\circ}C$ was 1 week and $2^{\circ}C$ and $5^{\circ}C$ was 3 weeks and 1 week in 'CR-Nongshim' cultivar, respectively. The storage period of 'Ryouckgwang' cultivar was 2 weeks, 4 weeks, and 2 weeks, respectively. Conclusively, storage at $2^{\circ}C$ with more than 90% RH was recommended as optimum temperature to maintain quality in both cultivars.

본 연구는 여름철에 고랭지 지역에서 재배되는 8종류 배추의 품종별 품질 특성을 조사하고 '력광'과 'CR-농심'의 적정 저온저장 조건을 제시하기 위해서 수행되었다. 7월에 조기 수확한 품종은 9 월에 수확된 배추에 비해서 낮은 구중을 보이는데, 이는 7월의 배추 수확기간 동안 강원도 지역의 기상조건 악화에서 기인한 것으로 보인다. 배추 품종별 경도는 10N 이상으로 '청옥', '상장군', 그리고 '력광'에서 높게 나타났다. 관능평가 결과의 경우 외관, 신선함, 그리고 조직감은 배추 품종에 따른 차이가 없었다. 관능평가 항목 중 단맛은 '력광'이 가장 높고, 'CR-농심'과 '슈퍼춘광'이 그 다음을 이었고, 쓴맛은 'CR-농심'과 '수호'에서 높았다. 저장조건 최적화를 위한 실험에 이용된 배추는 'CR-농심'과 '력광'으로 고랭지 지역에서 80일 동안 재배된 것을 수확하여, $0^{\circ}C$, $2^{\circ}C$, $5^{\circ}C$, 그리고 $25^{\circ}C$의 상대습도 90% 이상조건에서 저장하였다. 상온저장은 품종에 상관없이 저장기간은 3일 이내로 무게손실률은 15% 이상을 보이고 있고, $0^{\circ}C$$5^{\circ}C$ 처리구에서는 각각 18%와 20% 이상의 무게손실률을 보였다. 그러나 $2^{\circ}C$에 저장할 경우 저장기간은 두 품종 모두 3주 이상으로 연장되었다. 경도는 'CR-농심'이 '력광'에 비해서 높으며 각 온도별 저장기간 동안에 유의적 차이가 없었다. 관능평가 항목 중 외관 모습은 배추의 저장 가능기간을 판단할 수 있는 품질 인자였다. 'CR-농심'은 $0^{\circ}C$, $2^{\circ}C$, 그리고 $5^{\circ}C$에서 저장 가능기간이 각각 1주, 3주, 그리고 1주인 반면 '력광'은 2주, 4주, 그리고 2주 동안 가능하였다. 'CR-농심'과 '력광'의 저장기간 동안 품질유지를 위한 저장온도는 $2^{\circ}C$ 온도조건이 최적저장 온도였다.
