用途:饲料中加入甜菜碱具有保护饲料中维生素的作用.饲料能耐高温.存贮期长.能大大提高饲料的利用率.而且还可以降低成本.鸡饲料加入0.05%的甜菜碱.能代替0.1%的蛋氨酸,饵料中加入甜菜碱对鱼虾有诱食作用.可大量用于水产品的彭化剂,猪饲料中加入甜菜碱.猪爱吃.而且瘦肉率提高.1kg甜菜碱相当于3.5kg的蛋氨酸.甜菜碱提供甲基的能力为氯化胆碱的1.2倍.是蛋氨酸的3.8倍.饲效十分显著.
生产方法:(1) 提取法.甜菜制糖的母液中含有12%-15%的甜菜碱.可以直接回收.将300份母液加热至50℃.加入80份氯化钙.搅拌一定时间后趁热过滤.滤液用盐酸酸化后冷却至20-30℃结晶.经分离.干燥得甜菜碱约30份.
(2)合成法.由氯乙酸与三甲胺季铵化而得.
用16%的氢氧化钠溶液将195份48.6%的氯乙酸水溶液中和成氯乙酸钠溶液.然后与360份16.4%的三甲胺溶液混合.于50℃下通气1h.于80℃下再通气1h.反应物稀释后经离子树脂(Dowex-50-8)吸附.氨水洗脱得甜菜碱溶液.再经真空浓缩.结晶得成品.
