Abstract
Determinations of minerals were made on the samples of human milk and of commercial modified milk powder in Japan, in order to elucidate problems for improvement of milk powder.
Following ten elements, namely, K, Na, Ca, Mg, P, Cl, Fe, Cu, Mo and Zn were determined, and their “standard contents” were 50mg, 15mg, 26mg, 4mg, 14mg, 38mg, 76μg, 27μg, 0.2μg and 201μg, respectively, which were represented as mean value from the samples which had been obtained from Japanese women during the period of 2 to 4 months after parturition.
All the samples of modified milk powder under investigation had been those on the market in Japan since 1953, and problems on the improvement for humanization in respect of minerals were considered.
Discussions were based rather on general balance of minerals than on individual element in milk, although relatively higher content of Zn in milk powder was noted.
