低磷牛奶的制备

Preparation of low- phosphorus milk

本文主要讨论合成勃姆石有效去除牛奶中磷酸离子的能力。将勃姆石加入牛奶中,滤过后通过对滤液中总磷、磷酸离子和其它成分的浓度测定,发现勃姆石能有效地吸附牛奶中的磷酸离子,吸附量与处理时间和勃姆石添加量而定。处理后牛奶中有机磷和其它乳成分的含量未发生改变,说明低磷牛奶的质量与处理前基本相同。

The ability of synthetic boehmite to remove phosphate ions from milk was investigated. Boehmite was added to samples of milk, and the concentrations of total Phosphorus, phosphate ions and other substances in the filtrates were measured after filtration .It was found that boehmite adsorbed phosphate ions efficiently and that the adsorption depended on treatment time and on the amount of boehmite. Since levels of Phosphorus bound to organic substances and ingredients in the milk did not change, the quality of the milk was considered to be the same as that of the oringinal milk.
