초록

본 연구에서는 비름나물, 참취, 민들레, 미나리, 부추, 곰취, 홑잎나물 등 식생활에서 많이 섭취되고 있는 7종 나물의 생시료와 데친 후의 수분, 단백질, 지질, 회분, 무기질, 식이섬유와 비타민 함량 등 영양성분 변화를 비교 분석하였다. 데치기 전후 7종 나물의 수분 함량은 각각 71.28~92.68 g/100 g과 76.90~92.09 g/100 g으로 시료 간 유의적인 차이를 나타내었다(P<0.05). 영양성분 비교 분석을 위해 수분을 제외한 모든 성분의 함량은 건조물 중량 100 g 기준으로 환산하였다. 단백질 함량과 조지방 함량은 곰취가 33.38 g/100 g과 4.50 g/100 g으로 분석시료 중 가장 높은 함량을 나타내었다. 조회분 함량은 비름나물이 19.89 g/100 g으로 가장 높은 함량을 나타내었고 홑잎나물에서 5.21 g/100 g으로 가장 낮은 함량을 나타내었다. 무기성분 중 칼슘 함량은 비름나물이 1,534.44 mg/100 g으로 가장 높은 함량을 나타내었으며 그다음으로 곰취, 민들레, 홑잎나물, 참취, 부추, 미나리 순으로 시료 간 유의적인 차이를 나타내었다(P<0.05). 철 함량은 민들레가 55.23 mg/100 g으로 가장 높은 함량을 나타내었으며, 나트륨 함량은 비름나물이 743.18 mg/100 g으로 기타 채소에 비해 유의적으로 높은 함량을 나타내었다. 칼륨과 마그네슘 함량은 비름나물에서 각각 7,710.63 mg/100 g과 1,786.67 mg/100 g으로 가장 높은 함량을 나타내었다. 총 식이섬유는 홑잎나물, 부추, 미나리, 비름나물, 곰취, 참취, 민들레 순으로 홑잎나물에서 59.75 g/100 g으로 가장 높은 함량을 나타내었다. 리보플래빈 함량은 곰취와 참취가 각각 3.10 mg/100 g, 3.08 mg/100 g으로 기타 채소보다 유의적으로 높은 함량을 나타내었다(P<0.05). 비타민 C 함량은 홑잎나물에서 468.28 mg/100 g으로 기타 나물보다 유의적으로 높은 함량을 나타내었으며 민들레 시료는 22.48 mg/100 g으로 가장 낮은 함량을 나타내었다. 주요 영양소 권장섭취량에 대한 기여도를 보면 단백질, 칼슘, 식이섬유, 비타민 등 성분에 대해서는 홑잎나물이 기여도가 높았다. 철 성분은 민들레가 기여도가 컸으며 칼륨, 마그네슘, 나트륨 등 성분은 비름나물이 성인 권장섭취량에 대한 기여도가 높았다. 이상의 결과로부터 나물은 종류에 따라 영양성분 함량의 차이가 있으며, 어느 한 종류의 나물을 섭취하기보다 여러 가지 나물을 골고루 섭취하는 것이 바람직할 것으로 생각된다.

This study examined the nutritional compositions of seven raw and blanched green vegetables: Amaranthus mangostanus L. (AM), Aster scaber Thunberg, Taraxacum platycarpum H. Dahlstedt (TP), Oenanthe javanica (Blume) DC, Allium tuberosum Rottler, Ligularia fischeri (Ledeb.) Turcz (LF), and Euonymus alatus (Thunb.) Siebold (EA). Proximate compositions (moisture, protein, ash, dietary fiber, and fat), minerals (calcium, phosphorus, iron, potassium, sodium, and magnesium), and vitamins (riboflavin and vitamin C) were analyzed in the study. In this study, moisture contents of raw and blanched green vegetables were 71.28~92.68 g/100 g and 76.90~92.09 g/100 g, respectively. The protein and fat contents of raw LF (33.38 g/100 g and 4.50 g/100 g dry weight basis, respectively) were higher than those of other cultivars. Ash contents of AM were significantly higher than those of their respective raw samples. Potassium, magnesium, calcium, and sodium contents of AM were 7,710.63 mg/100 g, 1,786.67 mg/100 g, 1,534.44 mg/100 g, and 743.18 mg/100 g, respectively. In the case of raw green vegetables, iron content of TP was 55.23 mg/100 g, which was the highest value among tested green vegetables. Total dietary fiber content of EA was 59.75 g/100 g, which was the highest value. Riboflavin content was highest in the raw and blanched LF (3.10 mg/100 g and 3.05 mg/100 g, respectively). Vitamin C contents of raw and blanched EA were 468.28 mg/100 g and 471.42 mg/100 g, respectively, which were higher than the other values. There were differences in nutritional ingredients according to different types of green vegetables. Therefore, it is advisable to evenly ingest various green vegetables.
