Abstract
The quantitative changes of constituents in early lactation milk were analyzed chemically, and the colloidal properties of milk were experimented by the method of ultrafiltration.
The following results were obtained.
Thoughthe amounts of each component, except lactose, phosphorus, and calcium, were higher in early lactation milk than in ordinary milk, these generally showed a tendency to decrease with the progress of the lactation stage and on the contrary, the amounts of lactose and phosphorus showed the reverse tendency.
The amount of soluble calcium in human milk were higher than that in cow milk. So, it was suggested that the colloidal properties of human milk and cow milk were different.
