초록

본 연구는 귤피가루를 활용하여 모닝빵을 개발하고 이를 대학기숙사에 거주하고 있는 과체중 및 비만인 20대 남 녀에게 섭취하게 해봄으로써 아침결식률을 낮출 수 있는 새로운 식품 소재를 개발하고자 실시되었다. 체중과 BMI의 경우 GB 섭취군과 CPB 섭취군 모두에서 감소하였으며, CPB 섭취군에서 사전에 비해 사후 유의적으로 체중과 BMI가 감소한 것으로 나타났다 (p < 0.05). WHR은 GB 섭취군에서는 증가하는 경향을 보였으나 CPB 섭취군에서는 유의적으로 감소하였다 (p < 0.05). BFM은 두군 모두에서 유의적으로 증가하였으며 (p < 0.05) 군간에 유의성을 띄지 않았다. TC는 GB 섭취군에서는 증가하는 경향을 보였으나 CPB 섭취군에서는 유의적으로 감소하였다 (p < 0.05). HDL은 두군 모두에서 증가하였고 GB 섭취군에서 유의성을 보였다 (p < 0.05). LDL은 두군 모두에서 유의적으로 감소하였으며 (p < 0.05) 군간에 유의성은 없었다. GOT와 GPT는 GB 섭취군과 CPB 섭취군 모두에서 감소하였고 CPB 섭취군에서 유의성을 보였다 (p < 0.05). GB와 CPB를 섭취한 군간에 신체계측치와 혈액생화학적 수치에서 유의적인 차이를 보이는 항목은 없었으나 CPB 섭취군에서 사전에 비해 TC, LDL, GOT, GPT 수치가 유의적으로 감소하였다는 점에서 (p < 0.05) 본 연구는 시간적 흐름에 따라 변화를 추적하는 종단적 연구에 가깝다고 판단되며 본 연구를 통하여서 귤피가 심혈관계질환의 유병률을 낮춰줄 수 있는 잠재적 가능성이 있음을 임상적으로 확인하였다. 따라서 향후 본 연구와 유사한 연구들이 double blind cross-over study와 같은 대규모 임상연구로 진행되어 귤피의 지질관련 효과들을 보다 명확하게 입증해줄 필요성이 있을 것으로 판단된다.

Purpose: This study was conducted in order to develop morning bread using powdered citrus peels and to examine the effect of its several biological activities for 12 weeks in overweight adults ($$BMI{\geq_-}23$$) living in dormitories of Chonbuk National University. Methods: Control bread was prepared using the same formula except for replacing the wheat flour with 3% citrus peel powder. Subjects were classified according to two groups: Intake group of 3% citrus peel powder fortified morning bread (n = 30) and general morning bread (n = 30). Results: The results of our study showed no significant effects of citrus peel powdered morning bread on anthropometric indices and biochemical characteristics among overweight adults. Despite the slight reduction in total-cholesterol, LDL-cholesterol, GOT, and GPT (p < 0.05), no significant differences in changes of these values were observed between the two groups. Conclusion: The short duration of our intervention might have resulted in the lack of any significant effect. Therefore, conduct of further studies with longer duration is warranted in order that the results from this study can be utilized as a basis for the development of food products with citrus peel powder.
