【摘要】 鲁梅克斯ｋ － １ 酸模，是以鲜叶为主的新型高蛋白植物，单位蛋白产量为大豆的５倍。鲁梅克斯叶蛋白，又称为核酮糖双磷酸羧化酶，在绿叶中主要起酶促转化二氧化碳进行光合碳水化合物的作用，为酶活性蛋白质。鲁梅克斯叶蛋白的极性氨基酸分布在蛋白体外，使叶蛋白天然就具有良好的溶解特性。以ｐＨ３ 值制得的叶蛋白与４０ ％ 玉米油乳化，在质量分数为４ ％ 时，乳化能力为大豆分离蛋白的９ 倍，发泡能力和泡沫稳定性不仅高于大豆，也远大于鸡蛋蛋白。叶蛋白的必需氨基酸含量符合ＦＡＯ／ ＷＨＯ 按人体需要规定的模式值，为高营养全价蛋白。更多还原

【Abstract】 Rumex K-1,a new rich-protein green-leaf plant,can yield 5 times of protein per unit greater than soybean.Rumex,enzymatically active protein,which is also called Ribulosebisphosphate carboxylase/oxygenase(Rubisco),plays a key role in photosynthesis to transform carbon dioxide catalyzed by enzymes in green leaves.Leaf protein naturally possesses good solubitity,as polar amino acid residues locate on the protein surface and nonpolar hydrophobic side chains bury in the interior of the molecule in Rumex.When the leaf protein obtained at pH 3 was emulsified with 40% corn oil,the emulfication capacities of 4% concentration were 9 times greater than that of soybean protein isolate respectively,and the foaming property and foam stability were not only higher than that of soybean,but much higher than that of egg white.The leaf protein,that the content of EAA content accords with the requirement of FAO/WHO reference pattern,is an excellent nutritive value protein.更多还原
