재배 방법이 찰옥수수의 성분과 품질 특성에 미치는 영향을 규명하기 위해, 친환경 및 관행 방법으로 재배된 흑진주, 일미 및 연농1호 품종의 일반성분과 항산화활성을 분석하였다. 조회분은 흑진주, 일미 및 연농1호 모두 재배 방법에 따른 유의적인 차이를 보이지 않았고, 조지방은 흑진주에서는 친 환경 재배가, 일미에서는 관행 재배가 유의적으로 높았다. 조단백질은 흑진주에서는 친환경 재배가, 연농1호에서는 관행 재배가 유의적으로 높았다. 아밀로오스 함량은 친환경 재배에서 유의적으로 높았으며, 유리당은 흑진주에서 친환경 재배가 높았다. 아연 함량은 연농1호의 친환경 재배에서 유의적으로 높은 함량을 나타내었으며, 지방산은 연농1호 친환경 재배에서 palmitic acid, stearic acid 및 oleic acid 함량이 높았다. 비타민 E는 일미품종은 친환경, 흑진주와 연농1호는 관행 재배가 높아 품종 간에 차이를 보였다. 총폴리페놀 함량 및 전자공여능은 흑진주, 일미 및 연농1호 모두에서 친환경 재배보다 관행 재배에서 높게 나타났으며 총 항산화력 에서는 흑진주 관행 재배가 유의적으로 높았고, 일미에서는 친환경 재배에서 유의적으로 높았다. 이상의 결과로 부터 각 품종별로 다른 패턴을 나타내고 있어 일정한 차이를 인정하기 어려우며 따라서 각 품종별 우수한 측정 항목을 평가 하여 친환경 재배에 적합한 품종의 선발이 필요하다고 판단된다. The objective of this study was to investigate the chemical components and quality characteristics of three waxy corn varieties (Heukjinju, Ilmi, and Yeonnong1) harvested by conventional cultivation (CC) and environmentally-friendly cultivation (EFC). Crude ash content of the three corn varieties was higher, but not significant, in CC than EFC. Crude fat and protein contents in Heukjinju were higher in EFC, and amylose content was significantly higher (p<0.001). Free sugar, minerals, and fatty acid composition patterns varied according to the cultivation method. Vitamin E contents in the Heukjinju and Yeonnong1 cultivars were higher in CC than EFC. Total polyphenol content of waxy corns on EFC and CC were 175.28 and 204.00 ㎎/100 g, respectively, in the Heukjinju cultivar (p<0.01), and 148.64 and 158.42 ㎎/100 g, respectively, in the Ilimi cultivar, and 123.24 and 128.30 ㎎/100 g, respectively, in the Yeonnong1 cultivar. 2,2-Diphenyl-1-picrylhydrazyl radical scavenging activity on EFC and CC was 1.51 and 1.76 in Heukjinju cultivar (p<0.05), 0.29 and 0.34 in Ilmi cultivar (p>0.05), and 0.39 and 0.42 ㎎ trolox eq/g in Yeonnong1 cultivar (p>0.05), respectively. However, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonate) radical scavenging activity was higher in CC than EFC.

BACKGROUND: It is very important to monitor the residual characteristics of pesticides in pre-harvest fresh ginseng to ensure consumer safety. METHODS AND RESULTS: Forty-eight fresh ginseng samples were collected from 8 ginseng-growing fields 10 days before harvest and pesticide residues in fresh ginseng with and without rhizome (head of ginseng) and rhizome were analyzed for 320 pesticides by using GC-MS/MS and LC-MS/MS. As a result of the pesticide residue analysis, the number of pesticides detected from the fresh ginseng with rhizome, that without rhizome and rhizome were 26, 25, and 40, respectively, indicating that high number of pesticides found in rhizome, compared with the other parts. Pyraclostrobin was detected with the highest frequency in all samples, reaching to 21.2% in fresh ginseng with rhizome, 16.8% in that without rhizome, and 14.8% in rhizome. CONCLUSION: The residue levels of pesticides detected did not exceed their maximum residue limits, in spite of residual data in fresh ginseng before harvest. The amounts of the estimated daily intakes of all the detected pesticides were found to be from 0.018 to 1.818% of their acceptable daily intakes, indicating that concentrations of pesticides detected from fresh ginseng with and without rhizome collected before harvest do not pose the immediate health risks.
