性质描述: 白色至黄白色结晶或结晶性粉。熔点275-282℃(293℃),无臭或略有臭味,味略甜。L-型的苦味,D-型的甜度与蔗糖相似。0.2%水溶液的pH为5.5-7.0。耐酸、耐光性差。溶于水(25℃时溶解度0.4%)、稀酸和碱,微溶于乙醇。
生产方法: 吲哚经缩合生成夹拉明(3-二甲氨甲基吲哚),进一步缩合生成α-羧酸乙酯-β(3-吲哚)-N-乙酰基-α-丙氨酸乙酯,经水解、脱羧、再水解生成DL-色氨酸。
用途: 营养增补剂、抗氧化剂,可添加明胶、玉米等色氨酸含量少的食品中。与赖氨酸、蛋氨酸、苏氨酸合用于牛肉、米、玉米等,可得最佳效果。DL-色氨酸经旋光折分制得L-色氨酸,是氨基酸输液及综合氨基酸制剂和重要成份,可治疗烟酸缺乏症。作为饲料添加剂,参与动物体内血浆蛋白质的更新,促进核黄素发挥作用,有助于烟酸及血红素的合成,可显著增加怀孕动物胎仔体内抗体,对泌乳期的乳牛和母猪有促进沁乳的作用。当畜禽缺乏色氨酸时,生长停滞,体重下降,脂肪积累降低,种公畜睾丸萎缩。
