Abstract

This study was carried out to investigate the nutritive value and functional proterties of chloroplastic protein and cytoplasmic protein which are a leaf protein concentrates of acacia. The results obtained are as follows; 1. The limited amino acids of chloroplastic protein and cytoplasmic protein in acacia leaf were methionine & tryptophan in both cases. 2. Digestibilities of chloroplastic protein and cytoplasmic protein were 72.59% and 60.24%, respectively. 3. Bulk density, water absorption, emulsifying capacity and emulsion stability of the chloroplastic protein and cytoplasmic protein were not greatly different from those of milk casein, but water solubilities of those were lower than that of milk casein. 4. Fat absorption of the cytoplasmic protein was similar to that of milk casein, but that of the chloroplastic protein was lower than that of milk casein.

아카시아 엽단백질(葉蛋白質)을 식량화(食糧化)할 목적(目的)으로 엽록체단백질(葉綠體蛋白質) 및 세포질단백질(細胞質蛋白質)을 조제(調製)하여 영양가(營養價)와 기능적(機能的) 성질(性質)을 조사(調査)한 결과(結果)는 다음과 같다. 1. 아카시아잎의 엽록체단백질(葉綠體蛋白質) 및 세포질단백질(細胞質蛋白質)은 methionine 과 tryptophan 이 제한(制限) 아미노산 이었다. 2. 소화율(消化率)은 엽록체단백질(葉綠體蛋白質)이 72.59%, 세포질단백질(細胞質蛋白質)이 62.24% 이었다. 3 부피밀도, 흡수도(吸水度), 유화능력(乳化能力)및 유제(乳濟)의 안정성(安定性)은 milk casein에 비해 별차이가 없으나 용해도(溶解度)는 상당히 낮았다. 4 세포질단백질(細胞質蛋白質)의 지방흡착도(脂肪吸着度)는 milk casein 과 비슷하나 엽록체단백질(葉綠體蛋白質)은 상당히 낮았다.
