초록

우리 사과의 낙과 및 등외품의 식품으로써 이용가치를 높이고 사과장아찌의 품질개선을 위한 기초자료를 제공하기 위해 지역 농가에서 생산한 각기 다른 여섯 품종의 사과를 사용하여 사과 장아찌를 제조하였으며, 숙성 및 저장 기간에 따른 이화학적 품질특성과 관능평가를 통한 사과품종의 적합성을 조사하였다. 전체적인 사과장아찌의 초기 수분함량은 14.19~16.94%였으나 숙성이 진행됨에 따라 평균 25%정도 증가하여 유지되는 경향을 나타냈다. pH는 품종에 상관없이 3.98에서 4.55 범위에서 거의 일정하게 유지되었으며, 총산도는 0.8~1.3% 범위에서 숙성 10일째 까지 다소 감소하다 증가하여 유지되었다. 숙성 중 당도는 초기 60~68%였으나 숙성 5일째에 34~27%로 감소하였으며, 그 후 25~23%의 당도를 유지하였다. 염도는 초기에 0.94~1.64%였으나 저장 중 증가하여 15일 이후 사용한 사과 품종에 상관없이 3.5~3.8%로 비슷하였다. 관능적 특성은 홍로 품종을 사용한 사과장아찌의 경우 맛과 식감이 좋은 것으로 평가되었으며, 쓰가루 품종을 사용한 경우 색과 맛이 비교적 우수한 것으로 평가되었다. 갈라 품종의 경우 색, 향, 맛, 조직감 모두 비교적 좋은 평가를 받았으며, 특히 맛과 향이 좋은 것으로 나타났다. 전체적인 기호도는 갈라 품종을 사용한 사과장아찌를 가장 선호하는 것으로 평가되었다.

Quality characteristics, such as moisture content, pH, acidity, sugar content, salinity, flavor, taste, color, and overall acceptance of apple Jangachi prepared with different apple cultivars were investigated after different times in storage. The initial moisture content of apple Jangachi was 14.19-16.94% according to cultivar. After 5 days of storage, the moisture content increased to 23.26-26.91%. The pH was 3.98-4.55 regardless of cultivar. Total acidity decreased at first and then increased slightly after 10 days in the range of 0.8% to 1.3%. The sugar content of apple Jangachi decreased from 60-68% to 27-34% on the 5th day and was maintained at 23-25% after 5 days regardless of apple cultivar. The salinity of apple Jangachi increased from 0.94-1.64% to 3.5-3.8% after 15 day regardless of cultivar. In the sensory evaluation, apple Jangachi prepared with the Gala cultivar was given the best ratings in overall acceptability.
