초록

본 연구에서는 품종 및 숙도에 따른 아로니아의 품질 특성 및 항산화활성을 비교하였다. 물성의 경우 숙도 단계에 따른 변화는 1단계에서 가장 높은 값을 나타냈으며, 숙도 단계가 지날수록 유의적으로 감소하였다. 색도는 품종에 따라 큰 차이를 보이지 않았고 숙도별로는 명도의 경우 1단계에서 높았다가 점차 감소하는 경향을 보였고, 적색도는 1단계에서 가장 낮았고 4단계 이후 유의적 차이를 보이지 않았다. pH는 Mckenzie 품종이 가장 높았고 숙도별로 비교한 결과 pH의 변화는 크지 않았다. 당도는 Viking 품종이 가장 낮았으며 숙도가 높아질수록 당도는 유의적으로 증가하였다. 라디칼 소거능은 숙도가 진행될수록 높은 활성을 나타내었다. 총 폴리페놀 함량 및 총 플라보노이드 함량은 숙도가 진행될수록 점차 감소하는 경향을 보였다.

Aronia has low preference because of astringent and bitter taste. Appropriate processing is essential for eating aronia. For the processing of aronia, the aim of this study is to provide basic information on the cultivar and ripening stages. Three varieties (Viking, Nero and McKenzie) were studied. We divided the stages of maturity into four levels based on color. The physicochemical properties were analyzed. In the case of hardness, the first stage of maturity was the highest, and there was no difference between varieties. As maturation progressed, brightness and yellowness gradually decreased, and redness was highest at the second stage. The sugar content was the lowest in the Viking and significantly increased with the maturity stage. The acidity was highest in the Viking. Nero showed the highest radical scavenging ability. Total polyphenols and flavonoids were the highest in Nero. The highest level was shown at the first stage by the ripening stage.
