英文名称:L-Lysine
CAS 号:56-87-1
分子式 :C6H14N2O2
相对分子质量:146.19
特性与用处:
白色或近白色自在流动性的结晶性粉末。几乎无臭。263~264℃熔化并分化。一般较安稳,高湿度60%以下安稳,60%以上则生成二水合物。与维生素C和维生素k3共存则易着色。碱性条件及直接与还原糖存在下加热则分化。易溶于水(40g/ml,35℃),
营养强化剂。用于强化食物中的赖氨酸。黑麦、米、玉米、花生粉等所含赖氨酸为限制氨基酸,小麦、芝麻、燕麦等所含赖氨酸为榜 限制氨基酸。日本的强化规则用量(以L-赖氨酸计):小麦粉、通心粉、速煮面等为150mg/100g;面包、饼干等为100mg/100g;速煮面50mg/100g。尚可用于蛋黄酱、牛乳、方便面等。
