Abstract
Milssal is a polished, partially gelatinized pressed wheat grain and it is being consumed in Korea. This study was conducted to establish 2 practical means of providing needed lysine to the Korean population through fortification of Milssal. The results are summarized as follow: Lysine infusion of Milssal was significantly higher than polished wheat grain and affected by such factors as time and concentration of infusion solution. Cooking characteristics including water-uptake ratio and expanded volume were apparently better than polished wheat. After conducting the series of fortification experiments under actual manufacturing conditions. a reasonable process was chosen. In the developed process. lysine HCl solution was sprayed instead of water to the cleaned and debranned wheat grains during the regular wetting process. There was no differences in appearance and taste of Milssal before and after fortification. Fortification of the protein of Milssal with lysine has been found to bring a significant improvement in the growth rate of rats and the protein efficiency ratio. Stability remained relatively high throughout the storage period(90 days at
우리 나라 평균 식단에서 부족되고 있는 lysine을 밀쌀에 정량적으로 강화(强化)함으로써, 밀쌀 자체는 물론 우리 나라 국민의 섭취단백질을 질적으로 향상(向上)시킬 수 있는 방안(方案)을 모색코저 본 연구를 시도하였다. 따라서 밀쌀을 lysine 강화대상 곡류로 정하고, 정맥(精麥)(polished wheat) 및 밀쌀의 물리화학적 성상, 공장규모에서의 강화실험, 강화밀쌀의 저장시험 및 영양실험을 행하여 다음과 같은 결과를 얻었다. 1. 밀쌀은 호화건고(糊化乾固) 및 균열상태를 보임으로서 경도(硬度)는 정맥(精麥)보다 낮았고, 수분(水分) 및 L-lysine HCl 흡수능(吸收能)은 정맥(精麥)이 더 낮았다. 그리고 정맥(精麥) 및 밀쌀의 L-lysine HCl 흡수능(吸收能)은 침지 L-lysine HCl 용액의 농도에 거의 비례하였고 침제(浸濟) 초기에 급격히 흡수(吸收)하였다. 그리고 이들의 취반특성(炊飯特性)도 다소 차이가 있었다. 2. 공장규모(工場規模)의 L-lysine HCl 강화에 대한 일련의 실험결과, 기존 밀쌀제조공정 중의 가수공정(加水工程)에서 강화함으로써 기존 시설을 효용(效用)할 수 있었고, 강화농도가 균일한 밀쌀제품을 얻을 수 있었다. 그리고 공정 중의 L-lysine HCl 손실율은
