Preserve Fruit

Fresh fruit is so desirable, while at the same time the season during which most varieties can be obtained is so transient, that various methods are resorted to for preserving it in as nearly a natural state as possible. The old-fashioned plans of pickling in salt, alcohol, or vinegar, or preserving in equal quantities of sugar, are eminently unhygienic. Quite as much to be condemned is the more modern process of keeping fruit by adding to it some preserving agent, like salicylic acid or other chemicals. Salicylic acid is an antiseptic, and like many other substances, such as carbolic acid, creosote, etc., has the power of preventing the decay of organic substances. Salicylic acid holds the preference over other drugs of this class, because it imparts no unpleasant flavor to the fruit. It is nevertheless a powerful and irritating drug, and when taken, even in small doses, produces intense burning in the stomach, and occasions serious disturbances of the heart and other organs. Its habitual use produces grave diseases.

What is sold as antifermentive is simply the well-known antiseptic, salicylate of soda. It should be self-evident to one at all acquainted with the philosophy of animal existence, that an agent which will prevent fermentation and decay must be sufficiently powerful in its influence to prevent digestion also.

The fermentation and decay of fruits as well as that of all other organic substances, is occasioned by the action of those minute living organisms which scientists call germs, and which are everywhere present. These germs are very much less active in a dry, cold atmosphere, and fruit may be preserved for quite a long period by refrigeration, an arrangement whereby the external air is excluded, and the surrounding atmosphere kept at an equal temperature of about 40° F. The most efficient and wholesome method of preserving fruit, however, is destruction of the germs and entire exclusion from the air. The germs are destroyed at a boiling temperature; hence, if fruit be heated to boiling, and when in this condition sealed in air-tight receptacles, it will keep for an unlimited period.

DRYING FRUIT.

This method of preserving fruit, except in large establishments where it is dried by steam, is but little used, since canning is quicker and superior in every way. Success in drying fruits is dependent upon the quickness with which, they can be dried, without subjecting them to so violent a heat as to burn them or injure their flavor.

Pulpy fruits, such as berries, cherries, plums, etc., should be spread on some convenient flat surface without contact with each other, and dried in the sun under glass, or in a moderate oven. They should be turned daily. They will dry more quickly if first scalded in a hot oven. Cherries should be first stoned and cooked until well heated through and tender, then spread on plates, and the juice (boiled down to a syrup) poured over them. When dried, they will be moist. Pack in jars. Large fruit, such as apples, pears, and peaches, should be pared, divided, and the seeds or stones removed. If one has but a small quantity, the best plan is to dry by mean of artificial heat; setting it first in a hot oven until heated through, which process starts the juice and forms a film or crust over the cut surfaces, thus holding the remaining: quantity of juice inside until it becomes absorbed in the tissues. The drying process may be finished in a warming oven or some place about the range where the fruit will get only moderate heat. If a larger quantity of fruit is to be dried, after being heated in the oven, it may be placed in the hot sun out of doors, under fine wire screens, to keep off the flies; or may be suspended for the ceiling in some way, or placed upon a frame made to stand directly over the stove. As the drying proceeds, the fruit should be turned occasionally, and when dry enough, it should be thoroughly heated before it is packed away, to prevent it from getting wormy.
