Abstract

This study investigated the changes in functional components of barley powder produced from different grain varieties (Dahan, Hinchalssalbori, Heukgwang, Huknuri and Boseokchal) and varying milling degrees (27, 23, 19, and 15%). Total polyphenol contents increased with a decrease in the milling degree, with content ranges of 0.97-1.40, 1.19-1.66, 1.22-1.77, 1.30-1.93, and 1.46-2.12 mg/g, respectively. Total flavonoids content also increased with a decrease in the milling degree. The total polyphenol and flavonoids contents were the highest in barley powder from Huknuri and Boseokchal grains. Total dietary fiber, arabinoxylan, and GABA contents increased with a decrease in the milling degree. As the milling degrees decreased, ${\beta}$-glucan contents, which was the highest in Hinchalssalbori and Boseokchal, decreased with ranges of 4.98-7.29, 5.26-7.03, 4.84-7.17, 4.84-700, and 4.66-6.33 mg/100 g, respectively. These results provide useful data for selection of an appropriate variety and milling degree to achieve a high quality in barley processing.

보릿가루의 활용도를 높이기 위하여 5가지 품종의 보리에 대한 도정도별 기능성분 변화를 분석하였다. 도정도별 총 폴리페놀 함량은 도정도가 27, 23, 19, 15%와 원곡으로 감소함에 따라 각각 0.97-1.40, 1.19-1.66, 1.22-1.77, 1.30-1.93과 1.46-2.12 mg/g 범위에서 증가하였으며, 총 플라보노이드 함량 또한 도정도가 감소함에 따라 증가하였으며, 유색보리인 흑누리와 보석찰이 높았다. 식품섬유 함량은 도정도가 감소함에 따라 각각 10.79-13.36, 10.78-14.34, 10.34-14.71과 10.47-14.87 g/100 g (원곡 18.21-21.22 g/100 g) 범위에서 증가하였으며, 베타글루칸 함량은 감소하였다. 찰성보리인 흰찰쌀과 보석찰이 식품섬유와 베타글루칸 함량이 높았다. 총 아라비노자일란 함량은 도정도가 감소함에 따라 증가하였다. GABA 함량은 도정도에 따라 각각 0.33-1.79, 0.33-1.84, 0.48-2.02와 0.55-2.26 mg/100 g (원곡 1.61-4.46 mg/100 g) 범위에서 증가하였으며, 품종에 따라 큰 차이를 나타내었다. 이상의 결과로 부터 보리를 이용한 가공제품을 개발하기 위해서는 가공적성을 파악하여 적합한 품종과 도정도를 결정하기 위한 연구가 진행되어야 할 것으로 판단된다.
