오가피 열수추출액의 유통 품질의 변화특성을 규명하기 위하여, 오가피( mesh)를 열수 추출한 액을 nylon/PE(0.08 mm) pouch로 밀봉포장하거나 포장하지 않고, 가온조건(40, )에서 10일간 보관하면서 1일 간격으로 이화학적 품질특성을 조사하였다. 보관 중 추출액의 탁도, pH, 총폴리페놀 함량 및 DPPH 유리기 소거능 등은 감소하는 경향을 보였으나 저온과 포장에 의해 감소가 억제됨을 보였다. 적정산도는 고온에서 증가함을 보였으

This study was conducted to investigate the effects of temperature and packaging on the quality characteristics of hot-water extract from Acanthopanax senticosus. The herb samples, ground and sifted( mesh), were extracted by a boiling() water under the atmospheric pressure for 2 hrs. The extract was packed with out nylon PE(0.08 mm) pouch and kept under the condition(40 and ) for 10 days. The reduction of turbidity, pH, polyphenol amount and DPPH radical scavenging activity of extract were retarded by packaging under the low temperature. Titratable acidity was increased with packaging at high temperature. Soluble solid content was not affected by packaging and temperature condition. The changes of quality characteristics followed the first-order reaction rate. Arrhenius equation was applied to determine the effects of temperature on the reaction rate constant, showing high . These results suggested that packaging under lower temperature can be utilized for maintaining the quality of A senticosus extract.
