oleopalmitin (so-called “oleomargarine”) is pressed out. The “oleo oil” is then mixed with 10 per cent of its weight of milk and a little butter color and churned. The product is then worked, salted, and constituted the “oleomargarine,” or butter substitute. Leaf lard can be worked in the same way as beef suet, and will yield an oleopalmitin suitable for churning up into a butter substitute.
II.—Fat from freshly slaughtered cattle after thorough washing is placed in clean water and surrounded with ice, where it is allowed to remain until all animal heat has been removed. It is then cut into small pieces by machinery and cooked at a temperature of about 150° F. (65.6° C.) until the fat in liquid form has separated from the tissue, then settled until it is perfectly clear. Then it is drawn into the graining vats and allowed to stand for a day, when it is ready for the presses. The pressing extracts the stearine, leaving a product commercially known as oleo oil which, when churned with cream or milk, or both, and with usually a proportion of creamery butter, the whole being properly salted, gives the new food product, oleomargarine.
III.—In making butterine use neutral lard, which is made from selected leaf lard in a very similar manner to oleo oil, excepting that no stearine is extracted. This neutral lard is cured in salt brine for from 48 to 70 hours at an ice-water temperature. It is then taken and, with the desired proportion of oleo oil and fine butter, is churned with cream and milk, producing an article which when properly salted and packed is ready for the market. In both cases coloring matter is used, which is the same as that used by dairymen to color their butter. At certain seasons of the year—viz., in cold weather, a small quantity of sesame oil or salad oil made from cottonseed oil is used to soften the texture of the product.
IV.—“Ankara” is a substance which in general appearance resembles a good article of butter, being rather firmer at ordinary temperatures than that substance, approaching the consistency of cocoa butter. It is quite odorless, but in taste it resembles that of a fair article of butter and, what is more, its behavior under heat is very similar to that of butter—it browns and forms a sort of spume like that of fat. Ankara consists of a base of cocoa butter, carrying about 10 per cent of milk, colored with yolk of egg. While not derived from milk, on the one hand, nor does it come from a single vegetable or animal fat on the other, {143} ankara may be considered as belonging to the category of the margarines. Ankara is obtained in the market in the form of cakes or tablets of 2 pounds in weight.
V.—Fresh butter, 150 parts, by weight; animal fat, 80 parts, by weight; sunflower oil, 40 parts, by weight; cocoanut oil, 30 parts, by weight.
VI.—Fresh butter, 100 parts, by weight; animal fat, 100 parts, by weight; sunflower oil, 80 parts, by weight; cocoanut oil, 20 parts, by weight.
VII.—Fresh butter, 50 parts, by weight; animal fat, 150 parts, by weight; sunflower oil, 80 parts, by weight; cocoanut oil, 20 parts, by weight.
It is seen that these three varieties contain respectively 50, 33, and about 16 per cent of cow’s butter. The appearance of the mixture is nearly perfect.
Formulas V to VII are for a Russian artificial butter called “Perepusk.”
To Impart The Aroma And Taste Of Natural Butter To Margarine.
—In order to give margarine the aroma and flavor of cow butter, add to it a fatty acid product, which is obtained by saponification of butter, decomposition of the soap, and distillation in the vacuum at about 140° F. The addition of the product is made upon emulsification of the fats with milk. The margarine will keep for months.
Harmless Butter Color.
—Alum, pulverized finely, 30 parts; extract of turmeric, 1 part. With the extract dampen the powder as evenly as possible, then spread out and dry over some hot surface. When dry, again pulverize thoroughly. Protect the product from the light. As much of the powder as will lie on the point of a penknife is added to a churnful of milk, or cream, before churning, and it gives a beautiful golden color, entirely harmless. To make the extract of turmeric add 1 part of powdered turmeric to 5 parts of alcohol, and let macerate together for fully a week.
To Sweeten Rancid Butter.
—I.—Wash the butter first with fresh milk and afterwards with spring water, carefully working out the residual water.
II.—Add 25 to 30 drops of lime chloride to every 2 pounds of butter, work the mass up thoroughly, then wash in plenty of fresh, cold water, and work out the residual water.
III.—Melt the butter in a water bath, along with some freshly burned animal charcoal, coarsely powdered and carefully sifted to free it from dust. After this has remained in contact for a few minutes, the butter is strained through a clean flannel. If the rancid odor is not completely removed, complete the process.
An English Margarine.
—A mixture of edible fats of suitable consistency, e.g., oleo oil, 5 parts; neutral lard, 7 parts; and butter, 1 part; is mixed with albuminous “batter,” 4 parts, with the addition of 1 part of salt as a preservative. If the albuminous constituent be composed of the whites and yolks of eggs beaten to a foam the product will have the consistency and color of butter. The molten fats are added to the egg batter and the whole is stirred at a temperature sufficient to produce coagulation of the albumen (150–200° F.). The mass is then cooled gradually with continuous stirring, and the salt is worked in.
Olive-oil Paste.
—If an ounce of peeled garlic be rubbed up into a pulp, in a clean Wedgwood mortar, and to this be added from 3 to 4 ounces of good olive oil, with constant rubbing up with the pestle, the oil becomes converted into a pasty mass, like butter. It is possible that the mucilage obtainable from other bulbs of the Lilium tribe would prove equally efficient in conferring semi-solidity on the oil, without imparting any strong smell. The above composition is largely used by the Spanish peasantry, instead of butter, which runs liquid in the Spanish summer. It is known as “aleoli.” The more easily solidified portion of olive oil is stearine, and this may be cheaply prepared from mutton fat. If added, in certain proportions, to olive oil, it would certainly raise its melting point.
BUTTERMILK, ARTIFICIAL.
Buttermilk powder, 10 parts; vinegar, 1 part; syrup of buckthorn, 1 part. Dissolve the powder in the water and add the vinegar and syrup. The powder is prepared as follows: Sodium chloride, 50 parts; milk sugar, 100 parts; potassium nitrate, 5 parts; alum, 5 parts. Mix.
