초록

건강 기능성이 강화된 커피음료의 개발을 위해 생리활성이 우수한 것으로 보고된 작두콩을 부소재로 선발한 후, 커피에 농도별로 첨가하여 커피음료를 제조하고, 항산화 효과를 평가하였다. 커피 추출방식에 따른 작두콩 첨가 커피를 대상으로 총페놀성 화합물의 함량 분석과 DPPH radical-scavenging 활성, 환원력, ABTS+ radical-scavenging 활성, hydroxyl radical-scavenging 활성 등의 생리활성 평가를 행한 결과, 모든 항목에서 작두콩 첨가에 따라 농도 의존적으로 활성이 향상됨이 확인되었다. 동물실험을 통한 cholestery ester hydroperoxide(CE-OOH) 생성 억제능에 있어서도 커피 한 잔 분량의 소량만을 쥐에 경구투여하였음에도 대조구에 비해 더 높은 CE-OOH 생성 억제 경향이 관찰되었다. 따라서, 작두콩 첨가 커피를 일상적으로 섭취할 경우 커피만을 음용하였을 때보다 카페인 저감효과 및 항산화능의 향상효과를 기대할 수 있을 것으로 판단되어 작두콩 첨가 커피의 상용화가 기대되는 바이다.

영어초록

Coffee is one of the most popular non-alcoholic beverages worldwide and is known to exhibit various beneficial therapeutic effects. Recently, studies on blending coffee, which contains added natural sources of biologically active compounds, have been published, with the aim of enhancing the health benefits of coffee-based beverages. For example, sword bean (SB) has been reported to exert various physiological activities and roasted SB is consumed as a coffee-like drink. Thus, we herein selected SB as a blending material to enhance the health function of coffee. SB-added coffee samples were prepared by mixing SB extract with coffee extract, and the antioxidant activities of the resulting mixtures were evaluated. The total phenolics content, DPPH radical-scavenging activity, reducing power, ABTS+ radical-scavenging activity, and hydroxyl radical-scavenging activity found to be directly proportional to the quantity of added SD extract. Moreover, inhibitory effects on the formation of cholesteryl ester hydroperoxides in copper ion-induced rat blood plasma oxidation were observed even upon the oral administration of only a small quantity of SD-blended coffee. It was therefore suggested that SB exhibits potential for use as a blending material for coffee beverages, whereby the intake of SB-added coffee may have more beneficial health properties in vivo compared to the intake of coffee beverages alone.
