    • Excellent sweetener compositions containing aspartame (APM) and APM derivative and being similar to sucrose in tasting properties, which can be easily, uniformly and efficiently produced at a high purity by the process for producing N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine methyl ester by the reductive alkylation of APM and 3,3-dimethylbutyraldehyde which comprises using 3,3-dimethylbutyraldehyde in an amount at most equimolar to APM for producing N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine methyl ester from a portion of the APM existing in the reaction system, then separating the reducing agent from the liquid reaction mixture, and effecting crystallization followed by the separation of the crystals thus precipitated.
    • 优良的甜味剂组合物含有阿斯巴甜(APM)和APM衍生物并且在品尝性质上类似于蔗糖,通过生产N- [N-(3,3-二甲基丁基)氨基甲酸酯)的方法可以容易地, -L-α-天冬氨酰基] -L-苯丙氨酸甲酯通过APM和3,3-二甲基丁醛的还原烷基化反应制备,该方法包括使用最多与APM等摩尔量的3,3-二甲基丁醛生产N- [N-(3 ,3-二甲基丁基)-L-α-天冬氨酰基] -L-苯丙氨酸甲酯从反应体系中存在的部分APM中分离出来,然后从液体反应混合物中分离出还原剂,并进行结晶,随后分离 晶体因此沉淀。
