Abstract
The product forming after oxidative acid digestion of the breast milk and the usage of ethyl ether or petroleum ether to remove the fat by solvent extraction has been identified as galactaric (mucic) acid, C6H10O8. This compound cannot be discarded, as its capability to form stable complexes with most important bioactive ions (Cu2+, Zn2+ Mg2+, and others) can lead to their vigorous sequestration from nitric acid solution before being measured by spectroscopic techniques.
