Malted Milk is a pure food prepared from rich full-cream milk, combined with the valuable nutritive extracts of malted barley and wheat. This product being highly concentrated and partially predigested, supplies a large amount of nutrition with little tax upon the digestive organs. It is a valuable nutrient in dyspepsia or impaired digestion, for fever and wasting diseases, the convalescent, nursing mothers, and the aged.
Peptonised Milk is milk in which the casein or curd has been made soluble and diffusible by means of the Peptonising Tubes. In these Peptonising Tubes, extractum pancreatis, containing the pancreatic ferment which acts especially upon the proteins of milk, is combined with soda bicarbonate in due proportion, and each tube contains sufficient peptonising powder to peptonise a pint of milk. Milk may be peptonised by various methods - by the "cold process," "immediate process," "warm process," etc. The method and degree of peptonisation suitable for any special case is soon determined by experience, by the agreeability of the milk and its digestibility.
Preservation of milk by condensation constitutes a very extensive commercial industry. There are several processes in vogue, and the product is either sweetened or unsweetened. Ordinary unsweetened milk contains about 12 per cent. each of protein and fat and 16 per cent. of the native milk sugar, making the total solids 40 per cent. Cane sugar may be added to the amount of about 40 per cent. more, making the total solids 80 per cent. Milk may also be condensed by forcing filtered air through it, until its volume is reduced to one-fourth the original amount. This product is sold in sterile bottles. Condensed milk is very generally used as a substitute for fresh milk. It is especially valuable in tropical regions and on ocean voyages. It is important that condensed milk be made from clean milk, and kept free from bacteria contamination. The unsweetened brands are especially liable to putrefaction, and should be cared for, when opened, like fresh milk.
When the process of condensation has been carried to complete expulsion of all fluid matter, a powder may be obtained which is sold as milk powder, desiccated milk, etc.
