Abstract

Although the global coffee market is growing every year and the demand for coffee wrapping paper is increasing accordingly, research on the effect of PE material and PP material on the coffee aroma used in the sealant layer, which will directly contact the product, is lacking. In this study, we studied the change of aroma patterns and flavor materials by adding coffee to PP and PE pouches. In addition, we observed changes in aroma patterns depending on the temperature and the presence of the deoxidizer. As a result, it was found that the PP type packaging material was slightly better than the PE type packaging material, but the performance was hardly changed by the material. Rather, the change in the aroma pattern due to temperature was dominant rather than the material. It is ideal that refrigerated distribution ($4^{\circ}C$) is the best storage temperature and sales are done within a short period of time. Among the indicators, pyridine was the most suitable material to study and there are many data about pyridine. Therefore, it is expected that the results can be derived by using pyridine.

전 세계적으로 커피 시장이 매년 커지고 있고 이에 따라 커피 포장지의 수요 역시 증가하고 있지만 제품에 직접적으로 접촉하게 될 씰란트 층에 사용되는 PE 재질과 PP 재질이 커피 향에 미치는 영향에 대한 연구는 부족한 실태이다. 본 연구에서는 전자코(Electronic nose)와 기체크로마토그래피와 질량분석기(GC/MS)를 이용하여, PP와 PE 재질의 파우치에 커피를 담아 향기 패턴과 향 물질의 변화를 연구해 보았다. 저장기간에 따른 휘발성분 분석 결과, 커피의 향기 성분 분석에 적합한 지표 물질은 pyridine이었다. 추가적으로 온도($4^{\circ}C$, $25^{\circ}C$ and $40^{\circ}C$)와 탈산소제의 유무에 따른 향기 패턴 변화 역시 관찰하였다. 그 결과, 미미하게나마 PP계열 포장재가 PE계열 포장재보다 보향성이 좋았으나 재질에 의한 성능의 변화는 거의 없다는 결과를 얻었다. 오히려 재질보다는 온도에 의한 향기 패턴 변화가 지배적이었다. 냉장 유통($4^{\circ}C$)이 가장 좋은 보관 온도였고 짧은 기간 내에 판매가 이루어지는 것이 이상적이다.
