Abstract
To investigate the effects of harvesting times on physicochemical and milling properties of rice, milling tests were performed applying laboratory milling systems. Milling and head rice yields were highest in rice harvested at the 45 days after heading at 76.49 and 94.43%, respectively. Milled rice grain harvested 45 days after heading showed the highest minimum viscosity, as shown in the amylogram curves, as well as the lowest consistency viscosity. Protein and amylose contents were highest in rice harvested at 35 days after heading, whereas the instrumental taste score was highest 45 days after heading.
수확시기가 벼의 도정특성과 이화학특성에 미치는 영향을 알아보고자 중만생 품종인 대안벼의 수확시기별 도정 특성을 조사한 결과, 출수 후 45일째(10월 15일) 수확시 도정율은 75.97%, 백미완전립율은 93.33%로 가장 높았다. 출수 후 35일에 조기 수확하면 단백질함량과 아밀로스함량이 높았다. 따라서 중만생 품종인 대안벼의 수확적기는 도정 및 이화학특성으로 볼 때 출수 후
