Abstract

The study was established to compare fruit qualities and antioxidant compounds in 'Niitaka' pear (Pyrus pyriforia) trees grown in the organic and conventional farming systems. Fruits in the organic system appeared to have dark red color on the fruit surface. Fruit weight, soluble solids, acidity, firmness, and stone cells were not different between the farming systems. Organic fruits had a greater potassium concentration than the conventional fruits, but phosphorous, calcium, and magnesium concentrations in fruits were not different between the treatments. Peel, flesh, and juice parts in the organic fruits had greater phenolic compounds compared to the conventional fruits. Peel parts had much greater antioxidant compounds than the flesh parts, regardless of the treated-fruits. All fruits grown in the conventional and organic systems had a similar DPPH ($\alpha$, $\alpha$-diphenyl-$\beta$-picryl-hydrazyl) radical-scavenging activity in the peel, but flesh parts in organic fruits had a greater DPPH than the conventional fruits. Phenol and flavonoid compounds in the peel and flesh were positively related to the DPPH radical-scavenging activity. There were no significant differences for the nitrite scavenging activity in the peel and flesh parts between the treatments.

본 연구는 유기재배와 관행재배 된 배 '신고' 과실특성과 항산화 활성을 비교하기 위해서 수행되었다. 유기농으로 재배된 과실은 진한 적색계열의 과피색을 보였고, 관행과 유기재배 된 과실의 무게, 당 및 산함량, 경도, 그리고 석세포 함량은 별다른 유의성이 나타나지 않았다. 과실 중 K는 유기재배에서 높았고, 다른 무기성분인 P, Ca, 그리고 Mg는 비슷한 농도를 보였다. 유기농 과실은 관행에 비교해서 과피와 과육 그리고 과즙에서 페놀함량이 유의적으로 높았고, 과피는 과육보다 재배방법에 상관없이 항산화 물질에서 모두 높은 함량을 나타냈다. DPPH 라디칼 제거능은 과피에서는 처리간에 별다른 영향이 없었고, 과육에서는 유기농 과실에서 관행보다 더 높게 나타났다. 페놀함량과 플라보노이드 모두 DPPH 라디칼 제거능과 강한 유의 상관관계가 나타났다. 배과육과 과피내 아질산염은 처리간에 비슷한 제거효과를 보였다.
