초록

생강이 가지고 있는 항산화력을 최대화 시키기 위해 다양한 제조 공정에서 흑생강을 제조하였다. 증숙 온도 및 시간에 따른 DPPH radical 소거능을 측정하였고, 이를 반응표면 분석법에 의해 최적화된 제조 공정을 선정하였다. DPPH radical 소거능을 최대화 할 수 있는 최적 점을 설정한 결과 93.2oC에서 6시간의 증숙 공정이 설정되었다. 제조한 흑생강을 음료로 개발하기 위해, 매실 농축액과 꿀을 혼합하여 기능성과 선호도가 높은 음료를 제조하였다. DPPH radical 소거능, 플라보노이드 함량, 관능평가의 canonical 계수를 이용하여 수적 최적화를 통하여 최적 배합비를 구한 결과, 흑생강 추출물 14.2%, 매실농축액 5%, 꿀 10.8%로 나타났고 desirability가 0.615로 설정되었다. 이때의 종속 변수값들은 DPPH radical 소거능 46.0 mg/L, 플라보노이드 함량 29.9 mg/L, 선호도 5.284로 예측되었다.

Black ginger, obtained from steaming and drying process, provides the various functional properties. This study was performed to investigate the optimum processing conditions for black ginger with high content of biologically active substance such as anti-oxidations. Optimum processing conditions such as temperature and time for black ginger was determined by response surface methodology (RSM) with manufacturing process and functionality. The optimum steaming condition was determined 6 hours at 93.2oC, and 82.7 mg/L DPPH scavenging activities was obtained at this condition. The black ginger drink was made with black ginger extracts, Japanese apricot, and honey. Interaction effects of these ingredients were investigated by modified distance based on design and analyzed by linear, nonlinear regression model, and RSM. The optimization of mixture ratio was made by statistical modeling using DPPH scavenging activities and sensory properties which are the important target constraints in drink. Total flavonoids showed a linear canonical form, while preference and antiradical activity showed a nonlinear canonical form indicating the higher interaction among mixtures. The response trace plot revealed that antiradical activity, sensory properties and total flavonoids were quite sensitive to the drink blending. The optimum formulation of the drink was set at 14.2% of black ginger extracts, 5% of Japanese apricot, and 10.8% honey.
