Previously we demonstrated that in very brief, one-bottle intake tests, human infants, both well nourished and protein calorie malnourished, ingested greater amounts of soup with added MSG compared with soup alone. The potentiating effect of MSG in plain aqueous solution was tested in the current experiments. In contrast to data with sucrose and salt solution, where infants preferentially ingest these compounds compared with a water diluent, aqueous MSG solutions were rejected relative to water. The implications of this observation for understanding the mechanisms of MSG perception and pleasantness were discussed.
此前我们证明，在非常简短的单瓶摄入测试中，营养良好和蛋白质热量营养不良的人类婴儿，与单独的汤相比，摄入了更多添加了味精的汤。在当前实验中测试了味精在纯水溶液中的增效作用。与蔗糖和盐溶液的数据相反，婴儿相对于水稀释剂更倾向于摄入这些化合物，而味精水溶液相对于水则被拒绝。讨论了这一观察结果对理解味精感知机制和愉悦感的意义。
