∗Preparations of stable protein complexes (SPCs) from nine types of human milk were lyophilized and the relative content of different elements in (mixture of the complexes from nine milk preparations) was determined by two-jet plasma atomic emission spectrometry; the relative standard deviation of the values from three replicates was within 5-7 %.
∗∗Average concentration of elements in the case of nine milk lyophilized preparations (see Table 2).
∗∗The data of two-jet plasma atomic emission spectrometry contained reliable peaks corresponding to some elements, but it was possible to estimate only their approximate concentration.
