Abstract

Mixed juice of pear and strawberry was fermented by commercial Saccharomyces cerevisiae C-2 at $25^{\circ}C$ for 7 days and obtained the pear-strawberry fermentative concentrates (PSFC). The PSFC showed high ACE inhibitory activity of 70.8%. The PSFC drink was prepared by using PSFC and by-materials including amylopeptide, and determined changes of quality and ACE inhibitory activity during storage of $20^{\circ}C$ and $40^{\circ}C$. PSFC drink was very stable at storage of $20^{\circ}C$ for 8 weeks without any quality and ACE inhibitory activity.

기호도가 높으면서 생리기능성이 우수한 배 음료를 개발하고자 배와 딸기를 혼합하여 시판 알콜 발효 효모인 Saccharomyces cerevisiae C-2로 발효시켰다. 이 발효액을 감압 농축하여 얻은 농축물로 음료를 제조한 후 $20^{\circ}C$$40^{\circ}C$에서 8주까지 저장하면서 품질과 생리 기능성변화를 조사하였다. 발효 농축물은 항고혈압활성인 엔지오텐신전환효소 (ACE) 저해 활성이 70.8%로 우수하였고 이를 이용하여 제조한 배 음료는 $20^{\circ}C$에서 8주까지 pH와 생균수 및 항고혈압성 ACE저해 활성 등이 큰 변화가 없이 안정하였다.
