흑마늘을 이용한 가공식품개발을 위해 흑마늘을 첨가(0, 1, 3, 5, 7%)한 쿠키를 제조하여 품질 특성을 알아보았다. 쿠키 반죽의 pH는 흑마늘 첨가에 의해 감소하였으며, 밀도 역시 영향을 받는 것으로 나타났다. 쿠키의 퍼짐성은 흑마늘 첨가에 의해 증가하였으며, 쿠키의 색은 L(lightness), b(yellow ness)값이 감소하고, a(redness)값이 증가하는 것으로 나타났다. 쿠키의 경도는 흑마늘 첨가량이 증가할수록 수분 함량이 증가하여 물러졌으며, 쿠키의 관능검사 결과 흑마늘 첨가에 의해 모든 항목(색, 냄새, 맛, 질감, 전체적인 기호도)에 영향을 미쳤고, 흑마늘 1% 첨가군과 3% 첨가군의 선호도가 가장 좋아 흑마늘 쿠키의 개발 가능성이 있는 것으로 확인되었다.
The principal objective of this study was to develop processed food with the effect of aged garlic by assessing the quality characteristics of cookies. Cookie samples were prepared with shredded aged garlic at varied levels of 0, 1, 3, 5, and 7%. The pH of dough decreased significantly with the addition of aged garlic. The spread factor of control samples also evidenced significantly higher values than the other samples. The results of a hardness assessment demonstrated that the addition of aged garlic exerted a significant effect on cookie hardness. The sensory evaluation showed that the properties of color, garlic aroma, and garlic taste of cookies tended to increase with increased levels of addition of aged garlic. The cookies with 1% and 3% added aged garlic had similar or significantly higher acceptance scores than the control cookies, for all properties except color.
