Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Differences in Dairy Products Milk is a fluid, and has been so regarded from time immemorial. It has been bought and sold by liquid measure. And in referring to the use of milk it is ordinarily spoken of as a fluid. We say commonly that we drink milk, and rarely speak of eating it. Yet milk is food rather than drink. It is the perfect food provided by Nature for the young of the most important grand division of the animal kingdom. And we know it is largely consumed as food by human beings of all ages. It is, then, as a food that milk, and chiefly the milk of the cow, is so conspicuous in commerce and in domestic economy. But our first idea of human food is a solid substance and although some food appears in a liquid form, it is valued for the solid matter it contains. Milk is no exception. It is a fluid because largely composed of water; but all its other constituent parts are solids, and they are what give milk its food value. Some of these constituents, the curd or caseine, the sugar and the salts or mineral matter, are dissolved in water; other parts, the fats, are in semi-solid particles, held in suspen sion in the fluid, causing the opaque appearance So milk is at once a solution and an emulsion. (by emulsion, a word itself meaning milk-like, we intend to describe a physical mixture of different substances like oil and water, which do not form a chemical union.) To thoroughly understand milk, its composi tion and value, it must, therefore, be examined chemically and physically.
