Aspartame is a dipeptide containing aspartic acid and phenylalanine methyl ester. It is a nutritive sweetener with a caloric value equivalent to that of other proteins and with sweetness approximately 180 times that of sucrose. Thus, for equivalent sweetening power, it contributes only 0.5% of the kilocalories of sugar. Numerous studies have shown no potential toxicity of amounts of aspartame likely to be ingested, or even of abuse doses. Although aspartame cannot fully replace sugar, it appears to be a safe and acceptable sweetener for those who must, or desire to, reduce their intake of sucrose.
阿斯巴甜是一种含有天冬氨酸和苯丙氨酸甲酯的二肽。它是一种营养性甜味剂，热值与其他蛋白质相当，甜度约为蔗糖的180倍。因此，就同等甜度而言，它所提供的热量仅为糖的0.5%。大量研究表明，摄入阿斯巴甜的正常量甚至过量量都没有潜在毒性。虽然阿斯巴甜不能完全替代糖，但对于那些必须或希望减少蔗糖摄入量的人来说，它似乎是一种安全且可接受的甜味剂。
