Abstract

This study investigated the quality characteristics of cookies added with the powder of pomace powder, which was produced as a by-product in Korean rice wine (Takju). The quality of cookies was evaluated based on moisture content, color, hardness, and sensory evaluation. Cookies were prepared by addition of 0, 5, 10, and 15% Takju pomace powders to basic flour formulation. The pH values of dough added with Takju pomace powder were 3.04-6.52, which was lower than that of the control group. The moisture contents of cookies were 6.92-6.52% and were lowest in cookies added with 15% Takju pomace powder. The L value was reduced according to the increase in Takju pomace powder. On the contrary, a value increased. Especially, a value of the control was negative (-0.96) while those of cookies added with Takju pomace powder were positive. There were no significant differences in the b value of these cookies. For texture, hardness of cookies was lowest in 15% Takju pomace powder cookies. The results of the sensory evaluation compared to cookies with 10% powder Takju pomace were superior in appearance, taste and overall preference.

본 연구에서는 탁주 부산물로 얻어지는 주박을 첨가한 쿠키를 제조하고 5-15% 수준으로 첨가하고 이에 따른 쿠키의 pH, 수분함량, 색도와 조직감, 관능평가를 통하여 품질특성을 조사하였다. 주박 분말의 첨가량을 달리하여 제조한 쿠키 반죽의 pH는 3.04-6.52 수준으로 주박 분말 5% 첨가구에서는 무첨가보다 낮아지고 10% 이상에서는 주박 첨가량이 증가할수록 pH는 높아지는 것으로 나타났다. 쿠키의 수분함량은 주박 5% 첨가 수준은 무첨가와 유의적 차이를 보이지 않으나 10% 이상의 첨가에서는 점차 낮아지는 경향을 보였다. 색도는 주박의 첨가량이 증가하면서 L 값과 b 값은 유의적으로 감소하는 경향을 나타내었으며 a 값은 증가하는 경향을 보였다. 관능평가를 실시한 결과, 주박 분말 10% 첨가구에서 외관과 맛에 대한 기호도가 가장 높은 것으로 평가하였고, 향과 질감 기호도에서는 5%가 가장 높았다(p<0.05). 종합적인 기호도가 가장 높은 것으로 평가한 주박 첨가량은 10%인 것으로 평가하였다.
