为降低Ａｓｐａｒｔａｍｅ生产成本，建立了１套水解二肽母液，并用离子交换树脂分离Ｌ苯丙氨酸的回收工艺。该工艺可使Ｌ苯丙氨酸回收率达７２％以上，且其质量完全达到生产Ａｓｐａｒｔａｍｅ的要求
In order to reduce the production cost of Aspartame, a set of hydrolyzed dipeptide mother liquor was established and the L-phenylalanine recovery process was separated by ion exchange resin. The process allows L phenylalanine recovery rate of 72% or more, and its quality fully meet the requirements of the production Aspartame
