Abstract

General component and mineral contents according to species of Capsicum annuum were investigated. In addition, chuichung cucumber, white dadagi cucumber, and yellowish overripe cucumber were cooked by using seven different methods (boiling, steaming, pan-cooking, roasting, pan-frying, deep-frying, and microwaving), and retention rates of general components and minerals according to species were evaluated. Weight loss was observed in all cucumber species using all cooking methods. Most general component and mineral contents of C. annuum samples were significantly different according to species, and cooking method (P<0.05), whereas Fe and Cu contents were not significantly affected by species and cooking method, respectively. As a result, the highest protein, fat, ash contents were detected in deep-fried C. annuum, and high moisture contents were detected in raw, boiled, and steamed C. annuum. High mineral contents were detected in roasted and microwaved chuichung cucumber, deep-fried white dadagi cucumber and yellowish overripe cucumber. Retention rates of C. annuum by cooking method, ranged from 30~100% for protein, 10~100% for fat, 35~90% for moisture, and 30~100% for ash. High retention rates were observed for minerals in boiled, roasted, and microwaved chuichung cucumber, and deep-fried white dadagi cucumber and yellowish overripe cucumber. However, in yellowish overripe cucumber, mineral retentions rate were remarkably lowered by boiling and steaming, resulting in rates of 20~45%. These results were the data used as the basis for development of cucumbers.

본 연구는 오이의 종류와 조리방법에 따라 일반성분 및 무기질 함량을 비교하고자 하였다. 오이는 취청오이, 백다다기오이, 노각 3종류를 생재료와 삶기, 찌기, 굽기, 로스팅, 볶기, 튀기기, 전자레인지 7가지 조리방법을 사용하였다. 이를 통해 일반성분과 무기성분의 잔존율과 각각의 함량에 대한 종류 및 조리방법의 상관성을 조사하였다. 실험에 사용된 오이는 모두 조리과정에서 중량이 감소하였다. 대부분의 일반성분과 무기질은 종류와 조리방법의 영향을 모두 받았지만 단백질은 영향을 받지 않았고, 철 함량은 조리방법에 의해 영향을 받지 않았으며, 구리 함량은 종류에 대한 영향을 받지 않는 것으로 나타났다. 일반성분 중 단백질, 지방, 회분은 튀기기 했을 때 함량이 높았고 수분은 원재료, 삶기, 찌기를 했을 때 높았다. 무기질은 로스팅과 전자레인지 조리를 한취청오이의 함량이 높았고, 백다다기오이와 노각은 튀기기를 했을 때 전반적인 함량이 높았다. 단백질, 지방, 수분, 회분의 잔존율은 각각 30~100%, 10~100%, 35~90%, 30~100% 범위로 나타났다. 무기질은 로스팅, 전자레인지, 삶기를 한 취청오이가 높은 잔존율을 보였고, 백다다기오이와 노각은 튀기기를 했을 때 높은 잔존율을 보였다. 취청오이는 찌기를 했을 때, 백다다기오이와 노각은 삶기와 찌기를 했을 때 잔존율이 낮았으며, 특히 노각의 경우 20~45%로 낮은 잔존율을 보였다. 이러한 결과들을 종합해 보았을 때 오이에 대한 조리 전후에 대한 기초 자료로 활용이 가능할 것으로 생각되며, 다양한 오이 종류에 대한 추가적인 연구가 필요할 것으로 생각된다.
