THE DAHL PROCESS OF STERILISING MILK.

The process patented by the late Mr Kristian Gerhard Dahl for preserving milk by sterilising it was explained to a number of visitors at the Salisbury Hotel, London, E.C. In this process fresh milk is placed in cans, which are hermetically scaled and then alternately heated and cooled until every trace of ah organism or germ has been destroyed. It is claimed that the milk, thus rendered completely sterile, may be kept in the unopened tins for an indefinite period until required for use. Milk was shown that had been thus kept for three years, and neither in taste nor appearance could it be distinguished from the best fresh milk. The sterilised milk has been found useful for export, and for use on steamers, yachts, &c. It has the advantage of being unsweetened. It is also claimed that there is no danger whatsoever of infection in its use ; that it is admirably adapted to the purpose of the nursery and the needs of the confectioner ; and that it can be converted easily into cream and There is one disadvantage which will be evident on consideration, and that is the balkiness of this form of preserved milk, both as regards storage and transport. Hitherto the Dahi proeess has been adopted only in Norway, but there is now a movement for introducing it into this country.—lndustries.
