The chemical composition, distribution of N and P compounds and fatty acid composition of composite milk from mothers in Sapporo were investigated.
1. The chemical compositions (total protein, fat, lactose and ash) were close to those prsented by NRC. Ca and P were less, but Na was more, than NRC values and those in the Standard Tables of Food Composition in Japan.
2. The ratio of casein: albumin-globulin: non-protein N was 43.0: 37.0: 19.1, -whereby the total N amounted to 181.4mg/100g milk. It seemd that casein N content was a little higher than those obtained for foreign woman milk, although the values in the foregoing literatures varied greatly in themselves.
3. Among several characteristics of fat, the iodine value took the highest numbers ever reported. Linoleic and linolenic acid contents were higher than those in foreign woman milk.
4. The ratio of acid-insoluble P: acid-soluble organic P: inorganic P, in total P of 12.9mg%, was 16.3: 47.3: 36.4. A majority of the acid-soluble P passed through collodion films. Total P of 91.0mg% in cow's milk, on the contrary, showed a higher percentage of inorganic P content, and 31.9% of it was impermeable colloidal P of inorganic nature.
