Abstract

With a view to improving the method of rice marketing quality estimation, vaietal milling characteristics and apparent qualities were studied and their statistical interrelationships were computed for 2 years crops, using 22 varieties of Japonica type and Japonica x Indica type (Tongil). The milling yield was the highest for Japonica, while the broken rice yields was the highest for Japa.xInd. type. But bran yield did not show any significant differences among rice types. Milling factors were volume weight of brown rice, dehulling yield, and Polishing yields; the better these factors, the higher the yield. High apparent quality milled rice with high milling yield were produced from rice types whose broken rice, chalked rice, husk yield and bran yield were little and/or low.

우리나라 쌀의 품종별 도정 및 품위특성을 조사하여 합리적인 시장성을 평가할 수 있는 방법을 모색하고자 일반계 쌀과 다수계 쌀의 품종별로 품위 및 도정특성을 조사 분석한 결과는 다음과 같다. 유형별 도정률은 일반계가 높고 쇄미율은 통일계가 높았으나 미강률은 큰 차이가 없었으며 벼에서 쌀까지의 도정률은 현미의 용적중, 제현율 및 현백률이 높은 품종이 요구되고 현미의 쇄립률, 심복백립률, 왕겨율, 쇄미율 및 미강률이 낮은 품종은 쌀의 품위 및 수율이 향상되었다.
