울릉미역취의 저장기간 연장을 위한 MAP기술을 개발하기 위하여, 포장재질과 저장온도가 품질 특성에 미치는 영향을 조사하였다. 울릉미역취를 6월경에 수확하여 PP, Antifogging-OPP, LDPE, Macroperforated-HDPE, Nylon/PE, PVC/PE 재질의 필름으로 밀봉포장하고 4, 10, 에서 저장하면서 포장내의 기체 농도와 품질 특성을 분석하였다. 저장온도 에서 포장 내의 산소 농도를 비교해보면 PP와 A-

Modified atmosphere packaging (MAP) was assessed in terms of extending the shelf life of Solidago virgaurea spp. gigantea. In June 2005 Solidago virgaurea spp. gigantea were harvested from Ulleung Island, packaged in PP, Antifogging-OPP, LDPE, Macroperforated-HDPE, nylon/PE, or PVC/PE film, then stored at 4, 10 or for up to 14 days. The concentration decreased to in the PP and A-OPP packaging, to in LDPE packaging, and to 2% in nylon/PE and PVC/PE packaging at . The concentration increased to 5% at in PP, A-OPP and LDPE packaging, but increased consistently in the nylon/PE and PVC/PE packaging. Weight loss was markedly reduced by all MAP films except M-HDPE, and which was enhanced with decreasing storage temperature. The soluble solids and pH were not affected by the packaging material at and , but were affected at . The highest score for sensory qualities (appearance, color and overall acceptability) was obtained for vegetables stored at in PP films. Our results show that MAP using PP films and storage can effectively maintain the quality of Solidago virgaurea spp. gigantea.
