Finally the residue of beef may be put into a bag and subjected to pressure to remove as much of the juice contained therein as possible. The difference between beef tea and soup stock, as will be seen, is largely in the filtering. The beef tea should retain the coagulated flocks, while in the soup stock they are removed. One pound of good lean beef and one pint of water yield about one-half pound of good beef tea. As in the case of soup stock, beef tea is not a very nutritive substance. It is, however, stimulating, and the nourishment which it contains is quickly absorbed. The soft, coagulated flocks of albumin are readily digested, and often a patient may be nourished for days on a preparation of this kind when he is in a condition which renders it impracticable to use either solid or other liquid foods. Beef tea is also made on a large commercial scale and with some degree of approximation to the home prepared article. For various reasons, however, which have already been advanced, a well made domestic beef tea which can be used as soon as prepared is to be preferred in all cases to the manufactured article. A beef tea properly made contains approximately the following composition: Water, 88.00 percent Meat bases, 3.50 „ Protein--soluble and flocculated, 8.00 „ Ash and salt, 1.50 „ =Dried and Powdered Meats.=--The preparation of dried meat has already been described. There has lately been placed upon the market a number of preparations dried and finely ground, under various names, fanciful and those of the manufacturer. Inasmuch as ordinary meats are largely composed of water, it is evident that if the water can be removed without impairing the quality of the meat, great expense in transportation would be saved and the use of preservatives would be unnecessary. Various attempts, therefore, have been made to place dried meats upon the market. The meat powders are not only offered in their natural state of desiccation but also are prepared with a more or less previous digestion. One of the most common of these meat powders is known as somatose, which has been made in large quantities, and sold throughout all parts of the world. It consists largely of albumoses rather than of peptones, but this is true of a great many of the so-called peptone preparations. The composition of somatose is represented in the following table (Allen’s Commercial Organic Analyses, Vol. IV, page 384): Water, 14.25 percent Albumin rendered soluble by alkali, 21.83 „ Albumin, 3.40 „ Albumoses, 33.96 „ Peptone, 3.06 „ Meat bases, 2.62 „ Ash and salt, 5.30 „
