FLAVOR AND COMPOSITION OF BUTTER

3. FLAVOR AND COMPOSITION OF BUTTER.--That the housewife may have an understanding of the food substances found in butter and also learn how to determine the quantity of butter needed for her family, she should become familiar with the composition of this food. The flavor of butter depends to a great extent on the kind of cream from which it is made, both sweet and sour cream being used for this purpose. Of these two kinds, sour cream is the preferable one, because it gives to the butter a desirable flavor. Still, the unsalted butter that is made from sweet cream is apparently growing in favor, although it is usually more expensive than salted butter. The difference in price is due to the fact that unsalted butter spoils readily.

4. So far as its food substances are concerned, butter is composed largely of fat, but it also contains water, protein in the form of casein, and mineral matter. The quantity of water contained in butter determines to a large extent the weight of butter, since water is heavier than fat; but as only 16 per cent, of water is allowed, butter that contains more water than this is considered to be adulterated. As very little milk is retained in butter, only a small percentage of protein is found in this food. However, a considerable quantity of mineral salts are present, and these make it more valuable than most of the other fats. Because of the nature of its composition--a very high percentage of fat and a low percentage of protein--butter is distinctly a fuel food, that is, a heat-producing food. Of course, there are cheaper fats, some of which are even better heat-producing foods than butter, but as their flavor is not especially agreeable to some persons, they are not used so extensively.

In view of the nature of the composition of this food, an ounce of butter a day is the average allowance for each person when the diet of a family contains meat and such other fats as lard, olive oil, etc. At the most, 1/2 pound of butter should be purchased each week for each member of the family for table use, and fats cheaper than butter should be used for cooking purposes.

PURCHASE AND CARE OF BUTTER

5. PURCHASING BUTTER.--As in the case of milk, in order that the housewife may judge the quality of the butter she purchases, she will do well to look into the cleanliness and sanitary condition of the dairy that produces it. Too much attention cannot be given to this matter, for if cream becomes contaminated from careless handling, the same contamination is liable to occur in the butter made from it. Butter that is produced in dairies that make large quantities of it usually has not much opportunity to become contaminated before it reaches the consumer, for it is generally pressed into 1-pound prints, and each one of these is then wrapped and placed in a paper carton. On the other hand, the farmer and the dairyman doing a small business do not find it profitable to install the equipment required to put up butter in this way, so they usually pack their butter into firkins or crocks or make it into rolls. When such butter goes to market, it is generally placed in a refrigerator with more butter of the same sort, some of which is good and some bad. As butter absorbs any strong odor present in the refrigerator and is perhaps cut and weighed in a most unsanitary manner, the good becomes contaminated with the bad. While butter of this kind is perhaps a few cents cheaper than that which is handled in a more sanitary way, it is less desirable, and if possible should be avoided by the housewife. In case butter is obtained from a certain farm, the conditions on that farm should be looked into for the same reason that the conditions in a dairy are investigated.

6. To be able to select good butter, the housewife should also be familiar with its characteristics. In color, butter to be good should be an even yellow, neither too pale nor too bright, and should contain no streaks. The light streaks that are sometimes found in butter indicate insufficient working. As to odor, butter should be pleasing and appetizing, any foreign or strong, disagreeable odor being extremely objectionable. Stale butter or that which is improperly kept develops an acid called butyric acid, which gives a disagreeable odor and flavor to butter and often renders it unfit for use.

7. CARE OF BUTTER.--The precautions that the farmer and dairyman are called on to observe in the making and handling of butter should be continued by the housewife after she purchases butter for home use. The chief point for her to remember is that butter should be kept as cold as possible, because a low temperature prevents it from spoiling, whereas a high one causes it to become soft and less appetizing. The most satisfactory place in which to keep butter is the refrigerator, where it should be placed in the compartment located directly under the ice and in which the milk is kept, for here it will not come in contact with foods that might impart their flavors to it. Should no refrigerator be available, some other means of keeping butter cold must be resorted to, such as a cool cellar or basement or a window box.

The way in which butter is bought determines to a certain extent the method of caring for it. If it is bought in paper cartons, it should be rewrapped and replaced in the carton each time some is cut off for use. In case it is bought in bulk, it should never be allowed to remain in the wooden dish in which it is often sold; rather, it should be put into a crock or a jar that can be tightly covered.
