Abstract

In this study, we evaluated the physicochemical and sensory characteristics of cookies containing various concentrations (0, 3, 5, 7 and 9%) of broccoli (Brassica oleracea var. italica Plenck) powder. Cookies containing broccoli powder evidenced significantly lower L value than were noted in the control. The L values of brightness decreased significantly with the addition of broccoli powder to the cookie formula. The a values also decreased significantly with the addition of broccoli powder. The b value of yellowness increased significantly with increasing amounts of broccoli powder added to the cookie formula. The spread ratio increased proportionally with the quantity of broccoli powder added to the cookie formulation. The loss rate and leavening rate of the samples to which 7% and 9% broccoli powder was added were higher than those noted in the samples to which 3% and 5% broccoli powder was added. In terms of hardness, the values were significantly reduced in accordance with the amount of added broccoli powder. The results of our sensory evaluation demonstrated that the sample to which 7% powder was added was significantly more preferable in terms of overall acceptability than others. The quality characteristics of the 7% added samples evidenced significantly similar or higher values as compared to those of the controls, raising the possibility of developments in health-functional cookies.

브로콜리 분말의 이용 가능성을 검토하기 위해 밀가루 양에 대한 브로콜리 분말 첨가량을 0%, 3%, 5%, 7%, 9%로 각각 달리 하여 쿠키를 제조한 후 물리적, 관능적 특성을 비교하였다. 명도를 나타내는 L값과 적색도를 나타내는 a값은 브로콜리 분말 첨가량이 증가할수록 유의적으로 낮아졌다. 황색도를 나타내는 b값은 3% 첨가구를 제외하고 브로콜리 분말 첨가량이 증가함에 따라 유의적으로 증가하였다(p<0.05). 브로콜리 분말 첨가 쿠키의 퍼짐성 측정 결과, 대조구에 비해 브로콜리 분말 첨가량의 증가에 따라 퍼짐성은 점차 증가하였다. 손실율은 3%와 5% 첨가구에서 대조구보다 다소 낮게 나타났으나 7%와 9% 첨가구는 브로콜리 분말 첨가량이 증가함에 증가하였다. 팽창율은 5% 첨가구까지는 대조구에 비해 낮게 나왔고 첨가 비율이 증가함에 따라 9% 첨가구는 대조구보다 높게 나왔다. 브로콜리 분말 첨가 쿠키의 경도 측정 결과 대조구에 비해 3% 첨가구에서 다소 증가하였으나 유의적인 차이는 없었고, 브로콜리 첨가량이 증가할수록 쿠키의 경도는 유의적으로 감소하였다(p<0.05). 브로콜리 분말을 첨가하여 제조한 쿠키의 외관, 향기, 색, 조직감과 전반적인 기호도에 대한 관능적 특성을 조사한 결과, 외관은 5%와 7% 첨가구가 대조구에 비해 선호도가 높은 것으로 유의성 있는 결과를 보였으며, 향기는 모든 첨가구에서 대조구보다 선호하는 것으로 나타났고 특히, 5%와 7% 첨가구가 높은 점수를 받았다. 색은 3%와 5% 첨가구에서는 대조구보다 낮은 점수를 받았고, 7%와 9% 첨가구는 대조구와 유의적 차이가 없었다. 조직감과 전반적 기호도에서는 대조구보다 선호도가 감소하는 것으로 나타났다. 관능적 특성 조사 결과를 종합해 볼 때 7%가 가장 기호도가 좋은 것으로 나타냈다. 본 실험에서는 브로콜리 분말을 쿠키 제조에 다양한 수준으로 첨가하여 브로콜리 분말 첨가 쿠키의 개발 가능성 검토 결과, 브로콜리의 이용성을 높임과 동시에 기능성을 고려한 기호식품의 하나가 될 수 있으리라고 생각 된다.
