"100毫升牛奶最多只能兑75毫升水（并加入0.54克三聚氰胺）。"
was calculated according to the solubility of melamine in water (0.31g/100 ml), so 0.54g/175ml

total "protein" = 2.23 g from 0.54 g melamine
+ milk protein 0.73x4 = 2.92 = 5.15 g

5.15 g protein / 175 ml = 2.94 g "protein" / 100 ml.

    - 97％从楼下捡来的，没核对，不过你那约等于一算就少好几毫升水：） (无内容) - blackbox (0 bytes) 2008-09-17, 12:46:09 (259710)

  - sorry, you are right (this time!). but melamine might be more soluable in fat. - baiguo (1 bytes) 2008-09-17, 10:47:45 (259646)
