전자선 조사에 따른 캠벨얼리 포도의 휘발성 유기성분의 조성과 저장 후(0, 30일)의 변화를 확인하고자 본 연구를 수행하였다. 캠벨얼리 포도에 0.25, 0.5, 0.75 및 1 kGy의 선량으로 전자선 조사한 후 SDE 방법으로 휘발성 유기성분을 추출하고 GC/MS로 분석하였다. 포도와 전자선 조사된 포도의 주요 화합물로는 butanol, hexanal, [E]-2-hexenal, hexanol, 3-methyl-butanol 등이 동정되었으며
Changes in volatile organic compounds were investigated during storage after electron beam irradiation. Grapes were irradiated at 0.25, 0.5, 0.75, and 1.0 kGy and stored for 1 month at . Butanol, hexanal, [E]-2-hexenal, hexanol, and 3-methyl-butanol were the major volatile organic compounds of grapes. The types of volatiles in irradiated grapes were similar to those of non-irradiated samples but concentration differed among treatments. Some volatile compounds decreased during storage, whereas others, especially the esters, increased. Concentration of most volatile compounds were higher in pre-stored grapes than in post-stored fruit (thus, during the 30 days after irradiation by e-beam). Consequently, concentration of volatile organic compounds either increased or decreased after e-beam irradiation but these changes did not correlate with irradiation dose.
