Abstract

This study was performed to examine the processibility aptitude for the addition of Dobyeong to pigmented rice bran extract. Dobyeong from pigmented rice was less bulky and coarser than Dobyeong-added pigmented bran extract. The viscosity and degree of retrogradation in Dobyeong-added Pigmented bran extract were lower than Dobyeong from pigmented rice, indicating that the inhibitory action of retrogradation was higher in Dobyeong-added pigmented bran extract. The scores for springiness, adhesiveness, cohesiveness, gumminess, and chewiness were increased in Dobyeong-added pigmented bran extract. Dobyeong-added pigmented bran extract showed a decreased natural flavor of pigmented rice and degree of retrogradation, but had higher scores in color values. Dobyeong-added pigmented bran extract was more acceptable in sensory evaluation. Based on these results, the use of rice-added pigmented bran extract instead of pigmented rice in rice-processed food has advantageous effects in terms of the palatability of polished rice and phytochemicals of pigmented non-polished rice. This study will help develop new health-promoting rice products.

본 연구에서는 유색미를 미강과 배유 부분으로 분리 활용함으로써 쌀 가공제품의 다양화에 대한 연구의 일환으로, 유색미 미강층 에탄올 추출물 일정량 첨가시켜 제조한 도병의 가공적성을 검토하였다. 일반미에 유색미 미강층 에탄올 추출물 0.5% 첨가하여 제조한도병과 유색미로만 만든 도병을 비교분석하였다. 연구결과 유색미 도병이 유색미 미강추출물을 첨가한 도병에 비해 부피가 줄어들어 있고 조직도 거침을 알 수 있다. 유색미 도병에 비해 유색미 에탄올 추출물을 첨가한 도병에서 점도가 더 낮게 나타나 유색미 단독으로 도병을 제조하는 것보다 일반미에 미강 추출분획을 첨가하여 도법을 제조하는 것이 노화억제 효과가 더 큼을 알 수 있다. 탄력성, 부착성, 응집성, 껌성 및 씹힘성은 유색미 도병에 비해 유색미 분획추출을 첨가한 도병에서 유의하게 증가하였고, 유색미 도병과 유색미 추출분획을 첨가한 찹쌀도병 간에 경도 차이는 없었다. 유색미 도병에 비해 유색미 에탄올 추출물을 첨가한 찹쌀도병은 유색미의 강한 향은 반감시키고, 노화가 덜 일어났으며 색감과 전반적인 기호도에서 높은 점수를 나타내었다. 따라서 유색미 미강추출물을 첨가하여 도병을 제조 할 경우 식품에서 중요한 기능인 기호성도 고려하면서 유색미의 생리활성물질까지 이용할 수 있으므로 건강 기능성 쌀 가공식품 제조용 신소재로서의 적극적인 활용이 가능할 것으로 사료된다.
