Abstract

${\beta}-Carotene$, vitamin E, and folate contents according to color and species of Capsicum annuum were investigated. In addition, four C. annuum species were cooked by using different methods (boiling, pan-cooking, pan-frying, deep-frying, steaming, roasting, and microwaving), and retention rates of ${\beta}-Carotene$, vitamin E, and folate affected by color and species were evaluated. Weight loss was observed in all paprika and pepper species using all cooking methods. ${\beta}-Carotene$ and folate contents of C. annuum samples were significantly different by color, species, and cooking method (P<0.05), whereas vitamin E contents were not significantly affected by species. ${\beta}-Carotene$, vitamin E, and folate contents (mg/100 g) of raw C. annuum showed ranges of 95.4 (green pepper)~2,441.1 (red pepper), 0.7 (green paprika)~4.2 (red paprika), and 6.2 (green pepper)~148.7 (red pepper). As a result, the highest ${\beta}-Carotene$, vitamin E, and folate contents were detected in deep fried red pepper, roasted red pepper, and boiled red pepper, respectively, among the cooked samples. Retention rates of C. annuum varied by cooking method, resulting in ranges of 77.3% (boiled red pepper)~356.4% (roasted green pepper) for ${\beta}-Carotene$, 2.0% (microwaved red pepper)~789.3% (deep-fried green paprika) for vitamin E, and 20.9% (microwaved red pepper)~445.1% (steamed green pepper) for folate. Over 75% retention rates were observed for ${\beta}-Carotene$, vitamin E, and folate in all samples except for red pepper. However, in red pepper, vitamin E and folate retentions were remarkably lowered by deep frying and micro-waving, resulting in rates of 2.0~32.1%. This study provides information on effective cooking methods for vitamin retention in C. annuum depending on color and species.

본 연구는 파프리카와 고추 간의 품종별, 색깔별로 나누어 조리방법에 따라 베타카로틴, 비타민 E, 엽산의 함량을 비교하고자 하였다. 또한, 4종류의 시료를 서로 다른 조리방법(삶기, 굽기, 볶기, 튀기기, 찌기, 로스팅, 전자레인지)을 사용하였고, 이를 통해 베타카로틴, 비타민 E, 엽산의 잔존율과 각각의 함량에 대한 색, 종류, 조리방법의 상관성을 조사하였다. 파프리카와 고추는 모두 조리과정에서 중량이 감소하였다. 베타카로틴, 엽산의 함량은 색깔, 종류, 조리방법의 영향을 받았고(P<0.05), 비타민 E의 함량은 영향을 크게 받지 않았다. 조리 전 시료의 베타카로틴, 비타민 E, 엽산 함량(mg/100 g) 범위는 각각 95.4(풋고추)~2,441.1(홍고추), 0.7(녹색 파프리카)~4.2(적색 파프리카), 6.2(풋고추)~148.7(홍고추)로 나타났다. 조리 후 베타카로틴, 비타민 E, 엽산의 함량은 각각 튀긴 홍고추, 로스팅한 홍고추, 삶은 홍고추에서 가장 높은 함량을 보였다. 잔존율의 경우 베타카로틴, 비타민 E, 엽산이 각각 77.3(홍고추-삶기)~356.4(풋고추-로스팅)%, 2.0(홍고추-전자레인지)~789.3(녹색 파프리카-튀기기)%, 20.9(홍고추-전자레인지)~445.1(풋고추-찌기)% 범위로 나타났다. 홍고추를 제외한 나머지 모든 시료에서 베타카로틴, 비타민 E, 엽산이 조리방법에 상관없이 75% 이상의 높은 잔존율을 보였다. 홍고추의 비타민 E와 엽산은 튀기기와 전자레인지에서 2.0~32.1% 범위로 낮은 잔존율을 보였다. 이러한 결과들을 종합해 보았을 때 파프리카와 고추의 조리 전후에 대한 기초자료로 활용이 가능할 것으로 생각하며, 전자레인지를 이용한 조리방법에 따른 영양소 파괴에 대한 추가적인 연구가 필요할 것으로 생각한다.
