Abstract
The physiochemical properties of eight different cultivars or newly bred lines of glutionous rice were investigated and obtained following results; (1) The gelatinizing temperature, blue value and alkali number of starch separated from the sample cultivars or lines were similar to those of starch from conventional cultivar Olchal. The expansive power of three newly bred lines were somewhat weaker than that of starch from conventional cultivar, but the expansive power of other four lines were similar to that of conventional cultivar. (2) pH of cooked rice of the ten sample cultivars or breeding lines showed no discernible differences rangeing from 6.54 to 6.60. (3) The degree of gelatinization of cooked rice of newly bred lines were rather lower than that of conventional ones, but the degree of their retrogradation were somewhat higher than that of conventional cultivars. (4) In order to improve the palatability of cooked rice of Tongil (common rice), glutinous rice were mixed in different rate. The results showed that a mix ratio of six per cent glutinous rice was most favourable. The acceptability of common Tongil rice was improved when it was cooked with four to six per cent of glutinous rice mixed, and it showed no significant difference from that of Akibare alone cooked rice. Also no difference was noticed among newly bred glutinous lines in the acceptability when they cooked with common Tongil rice mixed. (5) Injolmi, Yaksik, Misitgaru, Twipap and Yugwa were prepared from glutinous rice of sample cultivars and or breeding lines to study their characteristics in processing and their acceptability. The results indicated that the acceptability score of newly bred lines were lower than that of conventional cultivar in cases of Twipap and Yugwa, but in cases of Injolmi, Yaksik and Misitgaru, identical score was obtained from both of newly bred lines and conventional cultivars.
새로이 육종(育種)된 통일계(統一系) 찹쌀 7계통(系統)과 재래(在來) 찹쌀(Olchal) 1종(種)에 대해서 이들의 이화학적성질(理化學的性質) 및 조리가공특성(調理加工特性)을 조사한 결과는 다음과 같다. (1) 통일계(統一系) 찹쌀 7종(種)에서 분리(分離)한 전분(澱粉)의 호화온도(糊化溫度), blue value, alkali mumber는 표준 재래(在來) 찹쌀의 그것과 비슷하였다. 이들의 팽화력(膨化力)은 통일계(統一系) 찹쌀의 3계통(系統)이 대조 재래(在來) 찹쌀 전분의 그것보다 다소 약한 편이나 기타 4계통(系統)은 비슷하였다. (2) 10종의 시료쌀로 지은 밥의 pH는
