Abstract

This study aimed to evaluate the physicochemical and sensory properties of the cookies that were prepared with different concentrations [0, 0.5, 1, 2, 4, and 6 % (w/w)]. The pH of the cookie dough increased significantly at all garlic juice concentrations greater than 1%. The highest dough density value was 1.23, which occurred in the 2% added group; however there was no remarkable differences among the test groups. The spread factor of the cookies showed an inverse relationship with the garlic juice concentration as compared to the control group (10.63). Hardness decreased with increasing garlic juice concentration at levels greater than 1%, and it ranged from 1857.92 to 1695.02. In addition, the L-value decreased with increasing garlic juice concentration, while the a-value gradually increased. In the case of the b-value, however, no significant difference was found compared to that of the control group. In the sensory evaluation, the color of the cookies (3.44-5.11) increased dose dependently with the garlic juice concentration. Taste scores were higher with garlic juice additions over 2%; whereas flavor was considerably greater compared to that of control group. The overall acceptability of the garlic juice cookies was higher than that of the control group. From this investigation, the optimal concentrations of added garlic juice for improvements in cookie quality were found in the range of 1-2%.

마늘 즙을 0, 0.5, 1, 2, 4 및 6%(w/w)로 첨가하여 쿠키를 제조하여 품질특성을 분석하였다. 반죽의 pH는 1% 이상 첨가시 대조군에 비해 유의적으로 상승하였으며, 밀도는 2% 첨가시 1.23로 가장 높았으나, 첨가량에 대한 유의차는 없었다. 마늘 즙을 첨가한 쿠키의 퍼짐성 지수는 $7.51{\sim}8.20$의 범위로 대조군(10.63)에 비해 유의적으로 감소하였으나 첨가량에 따른 통계적인 유의차는 없었다. 경도는 1% 이상 첨가시에는 1857.92-1695.02 g의 범위로 마늘 즙의 첨가량이 증가함에 따라 유의적으로 감소되었다. L값은 마늘 즙의 첨가량이 많아질수록 감소되었고, a값은 증가되었으며 b값은 실험군간의 유의적인 차이가 없었다. 쿠키의 표면색에 대한 관능평가 결과 3.44-5.11로 마늘 즙의 첨가량이 많아질수록 더 어두워지는 것으로 평가되었으며 마늘 맛은 2% 이상 첨가시, 마늘 향은 1% 이상 첨가시 대조군보다 유의적인 차이로 높게 평가되었다. 전반적인 기호도는 1%와 2% 첨가군에서 대조군보다 높은 선호도를 보였으며, 마늘 즙을 첨가한 쿠키 제조시 적정 첨가 농도는 1-2%의 범위인 것으로 판단된다.
