Abstract

Effects of cultivation methods on quality characteristics, pasting characteristics, chemical components, and antioxidant activities of sweet potatoes (Ipomoea batatas (L.) Lam) were determined. The Brix degree, hunter color value, pasting characteristics, moisture, protein, and mineral contents of the sweet potatoes showed significant differences from cultivation methods. The total polyphenol and flavonoid contents of the methanolic extracts of the sweet potato's pericarp were higher than sweet potato's sarcocarp. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of the sweet potato's pericarp on the conventional culture and successful cropped hairy vetch culture was 776.38 and 715.20 mg TE/100 g sample. The 2,2'-azino-bis-3-ethylbenzo-thiazoline-6-sulfonic acid (ABTS) radical scavenging activity of the sweet potato's pericarp on the conventional culture and successful cropped hairy vetch culture was 708.03 and 708.58 mg TE/100 g sample. Generally, there was a difference in antioxidant compound content and radical scavenging activity on the methanolic extract of sweet potato with cultivation methods.

재배방법을 달리하여 재배한 고구마의 품질특성과 화학성분 및 항산화활성의 변화를 분석하여 고구마 친환경재배에 적합한 녹비작물 설정의 기초자료로 활용하고자 하였다. 녹비작물 재배 후 후작으로 재배한 고구마에 대한 당도 및 색도 등의 품질특성과 호화특성을 분석한 결과 전작물에 따라 유의적으로 차이를 보이는 것으로 나타났다. 수확된 고구마를 과피와 과육으로 분리하여 수분(62.5-80.6 g/100 g), 단백질(2.6-3.9 g/100 g) 등의 일반성분과 칼륨, 칼슘, 마그네슘, 나트륨 등의 무기성분 함량을 분석한 결과 전작물에 따라 유의적으로 차이를 보였다. 재배방법을 달리하여 재배한 고구마를 과피와 과육으로 구분하여 메탄올로 추출하여 총 폴리페놀, 플라보노이드 함량을 분석한 결과 과육보다 과피 추출물이 유의적으로 높은 함량을 보였다(p<0.05). 가장 높은 함량을 보인 처리구는 관행재배 방법으로 재배한 고구마(SP1)로서 과피 추출물에서 각각 9.38 mg GAE/g sample 및 5.57 mg CE/g sample으로 유의적으로 가장 높았다(p<0.05). DPPH 및 ABTS radical 소거활성 또한 항산화성분과 마찬가지로 과육보다 과피 추출물이 유의적으로 높은 활성을 보였으며(p<0.05), 관행재배 방법으로 재배한 고구마(SP1) 과피 추출물이 각각 776.38 및 708.03mg TE/100 g sample로 유의적으로 가장 높은 활성을 보였고, 헤어리베치 후작으로 재배한 고구마(SP2)가 각각 715.20 및 708.58mg TE/100 g sample로 비교적 높은 활성을 보였다. 이상의 결과에서 관행재배 방법으로 재배한 고구마(SP1)가 높은 항산화성을 보였으며, 헤어리베치 후작으로 재배한 고구마(SP2)가 그 다음의 항산화성을 보여 다른 작물에 비해 유리할 것으로 판단된다.
