Studies on Processing Techniques in Barley - Ⅱ. The Processing and Cooking Quality of Cut-polished Barley in Naked Barley
1981년 전남지방에서 생산된 쌀보리 '영산보리'를 공시하여 일반보리쌀은 농업기술연구소에 설치되어 있는 표준도정시설로, 할맥은 맥류연구소에서 확립된 할맥가공방법으로 가공하여 도정수율, 입형, 소요전력, 화학성분 그리고 취반특성을 구명한 결과는 다음과 같다. 1. 도정율은 일반보리쌀이 70.10%인데 비하여 할맥이 68.27% 였다. 2. 입장/입폭비율은 할맥이 2.88인데 일반보리 쌀이 1.36이었으며 천립중은 할맥이 9.5g인데 일반보리쌀이 18.5 g 이었다. 3. 가공중 소요전력은 일반보리쌀이 91.1 kW/1.000kg인데 비하여 할맥이 105.1 kw/1,000 kg 으로 할맥가공에서 140.0kW/1,000 kg 더 많이 소요되었다. 4. 단백질, MgO 함량은 할맥이 일반보리쌀에서 보다 높았으나, P2 O5, K2 O 및 Mn은 거의 차가 없었다. 5. 취반후 백도의 차이는 일반보리쌀이 45.5%, 할맥이 49.5%, 수분흡수율은 일반보리쌀이 225.7%, 할맥이 312.7 %, 팽윤성은 일반보리쌀이 283%, 할맥이 318%로 할맥이 일반보리쌀보다 각각 4.0, 87.0 및 35% 높았다.및 35% 높았다.
These studies were carried out to find out the polishing properties and cooking quality of the cut-polished barley. Naked barley, Youngsanbori which was produced in Chonnam province, Korea in 1981, was applied for this experiment. Polished barley was produced by the conventional method and cut-barley was manufactured by the method established by Wheat and Barley Research Institute. The yield of cut-polished barley was 68.2% and that of conventionally polished barley was 70.1 %. The ratio of length to width was 2.88 in cut-polished barley and that of conventionally polished barley was 1.36. And weight of 1,000 kernel was 9.5g in cut-polished barley and 18.5g in conventionally polished barley. Energy consumption was found to be 91.1
