Summary:Green coffee beans (CB, Indonesian Mandheling) were fermented with three kinds of mushrooms (Phellinus linteus, PL; Hericium erinaceum, HE; Ganoderma lucidum, GL) or two kinds of mycelia from molds (Monascus purpureus, MP; Monascus ruber, MR) using solid-state culture to enhance physiological activity. After the roasting of fermented green coffee beans, roasted coffees were extracted with a hot-water decoction or 95% ethanol reflux. Yields from hot water extracts (HW, 17.7~25.3%) were higher than those from ethanolic extracts (EE, 9.5~12.2%). Hot-water extracts of roasted coffees from green coffee beans fermented with two molds (MP-CB-HW and MR-CB-HW) showed higher total polyphenols, flavonoids, and DPPH free radical scavenging activity than roasted coffees from non-fermented (CB-HW) or fermented green coffee beans with the three mycelia from mushrooms. MR-CB-HW also had the most potent macrophage stimulating and mitogenic activity (1.32 and 1.40-fold of CB-HW, respectively). In addition, MP-CB-EE and MR-CB-EE did not show any cytotoxicity to the RAW 264.7 cell at a concentration of $100{\mu}g/mL$, and these extracts significantly inhibited nitric oxide (NO) production from the LPS-stimulated RAW 264.7 cell line (38.6 and 37.0% of the LPS-treated group). Meanwhile, the chlorogenic acid concentrations of MP-CB-HW or MR-CB-HW highly increased (to 76.21 or $76.73{\mu}g/mL$, respectively), but caffeine concentrations were not affected by solid-state fermentation. In conclusion, the physiological activities of roasted coffees were enhanced by the solid-state culture of green coffee beans with M. purpureus or M. ruber, suggesting that these roasted coffees could possibly serve industrial applications as functional coffee beverages. 커피의 생리활성을 증진시키기 위해 고체발효를 이용하여 인도네시아산 Mandheling 커피생두에 3종의 버섯 균사체(Phellinus linteus, PL; Hericium erinaceum, HE; Ganoderma lucidum, GL) 및 2종의 홍국균 균사체(Monascus purpureus, MP; Monascus ruber, MR)를 배양하였다. 균사체-고체발효 커피생두를 로스팅하여 얻은 원두커피는 decoction법에 의한 열수추출물과 reflux에 의한 에탄올추출물로 조제하였는데, 열수추출물(HW, 수율 17.7~25.3%)은 에탄올추출물(EE, 9.5~12.2%)보다 더 높은 수율을 나타내었다. 2종의 홍국균 균사체-고체발효 커피생두로부터 조제된 원두커피 열수추출물(MP-CB-HW, MR-CB-HW)은 비발효 원두커피 또는 3종 버섯 균사체-고체발효 원두커피 열수추출물보다 높은 총 폴리페놀 및 플라보노이드 함량과 DPPH 자유라디칼 소거능을 나타내었다. 또한, 홍국균 균사체-고체발효 원두커피 중에서도 MR-CB-HW는 가장 높은 마크로파지 활성과 마이토젠 활성을 나타내었다(CB-HW의 1.32배와 1.40배). MP-CB-EE와 MR-CB-EE는 $100{\mu}g/mL$의 시료농도에서 세포에 대한 독성을 나타내지 않으면서도 LPS로 유도된 RAW 264.7 세포의 산화질소(NO)의 생성을 효과적으로 억제하였다(LPS 처리군의 38.6과 37.0%). 한편, 홍국균 균사체를 이용한 고체발효는 카페인 함량에 영향을 주지 않으면서 클로로겐산을 유의적으로 증가시켰다($76.21{\sim}76.73{\mu}g/mL$). 결론적으로 원두커피의 생리활성은 M. purpureus 또는 M. ruber와 커피생두의 고체발효에 의해서 증진되었으며 이러한 결과는 홍국균-고체발효 원두커피가 기능성 커피음료의 소재로 이용될 가능성을 제시하는 것으로 사료된다.
