复合氨基酸输液的色泽是考察输液质量的重要指标。其考核方法是用72型分光光度计于430um波长、测得光密度不允许>0.008。使产品色泽发黄,光密度增加其主要原因,一是在制剂过程中充N_2不足或贮存过程瓶盖不严N_2外流;二是输液中存在还原糖,(特别是添加质量不纯的山梨醇),ε—氨基与还原糖羰基发生“Mallard Reaction”(美拉德反应而致。)本反应可 The color of the composite amino acid infusion is an important indicator of quality of infusion. The assessment method is the use of 72 spectrophotometer at 430um wavelength, the measured optical density does not allow> 0.008. Make product color yellow, the main reason for the increase of optical density, one is insufficient filling N 2 in the preparation process or the captive N 2 outflow in the storage process; the other is reducing sugar in the infusion (especially adding sorbitol with impure quality ), ε-amino and reducing sugar carbonyl “Mallard Reaction” (Maillard reaction caused.) The reaction can be
