Keeping Fruit Fresh
Of the numerous varieties of fruits grown in this country,
apples and pears are about the only ones that can be kept for any
length of time without artificial means. As soon as fruit has attained
its maturity, a gradual change or breaking down of tissues begins. In
some fruits this process follows rapidly; in other it is gradual. There
is a certain point at which the fruits are best suited for use. We call
it mellowness, and say that the fruit is in "good eating condition."
When this stage has been reached, deterioration and rotting soon
follow. In some fruits, as the peach, plum, and early varieties of
apples and pears, these changes occur within a few days after maturity,
and it is quite useless to attempt to keep them; in others, like the
later varieties of apples and pears, the changes are slow but none the
less certain. To keep such fruits we must endeavor to retard or prolong
the process of change, by avoiding all conditions likely to hasten
decay. Even with ordinary care, sound fruit will keep for quite a
length of time; but it can be preserved in better condition and for a
longer period by careful attention to the following practical points:—
1. If the fruit is of a late variety, allow it to remain on
the tree as long as practicable without freezing.
2. Always pick and handle the fruit with the greatest care.
3. Gather the fruit on a dry, cool day, and place in heaps or
bins for two or three weeks.
4. Carefully sort and pack in barrels, placing those most
mellow and those of different varieties in different barrels; head the
barrels, label, and place in a cool, dry place where the temperature
will remain equable. Some consider it better to keep fruit in thin
layers upon broad shelves in a cool place. This plan allows frequent
inspection and removal of all affected fruit without disturbance of the
remainder.
5. Warmth and moisture are the conditions most favorable to
decomposition, and should be especially guarded against.
6. The best temperature for keeping fruit is about 34° F., or
2° above freezing.
Another method which is highly recommended is to sprinkle a
layer of sawdust on the bottom of a box, and then put in a layer of
apples, not allowing them to tough each other. Upon this pack more
sawdust; then another layer of apples, and so on until the box is
filled. After packing, place up from the ground, in a cellar or
storeroom, and they will keep perfectly, retaining their freshness and
flavor until brought out. The Practical Farmer
gives the following rough but good way to store and keep apples:
"Spread plenty of buckwheat chaff on the barn floor, and on this place
the apples, filling the interstices with the chaff. Cover with the
chaff and then with straw two or three feet deep. The advantage of this
is that covering and bedding in chaff excludes cold, prevents air
currents, maintains a uniform temperature, absorbs the moisture of
decay, and prevents the decay produced by moisture."
The ordinary cellar underneath the dwelling house is too warm
and damp for the proper preservation of fruit, and some other place
should be provided if possible. A writer in the American
Agriculturist thus calls attention to an additional reason
why fruit should not be stored beneath living-rooms: "After late apples
are stored for the winter, a gradual change begins within the fruit. It
absorbs oxygen from the air of the room, and gives off carbonic acid
gas. Another change results in the formation of water, which is given
off as moisture. The taking up of oxygen by the fruit and the giving
off of carbonic acid, in a short time so vitiates the atmosphere of the
room in which the fruit is kept, that it will at once extinguish a
candle, and destroy animal life. An atmosphere of this kind tends to
preserve the fruit. There being little or no oxygen left in the air of
the room, the process of decay is arrested. Hence it is desirable that
the room be air tight, in order to maintain such an atmosphere."
The production of carbonic acid shows that a cellar in or
under a dwelling, is an improper place for storing fresh fruit. When
the gas is present in the air in sufficient proportion, it causes
death, and a very small quantity will cause headache, listlessness, and
other unpleasant effects. A fruit cellar should be underneath some other
building rather than the dwelling, or a fruit house may be built
entirely above the ground. A house to keep fruit properly must be built
upon the principle of a refrigerator. Its walls, floor, and ceiling
should be double, and the space between filled with sawdust. The doors
and windows should be double; and as light is undesirable, the windows
should be provided with shutters. There should be a small stove for use
if needed to keep a proper temperature in severe weather.
To
Keep Grapes.—Select such bunches as are perfect, rejecting
all upon which there are any bruised grapes, or from which a grape has
fallen. Spread them upon shelves in a cool place for a week or two.
Then pack in boxes in sawdust which has been recently well dried in an
oven. Bran which has been dried may also be used. Dry cotton is
employed by some. Keep in a cool place.
Some consider the following a more efficient method: select
perfect bunches, and dip the broken end of the stems in melted
paraffine or sealing wax. Wrap separately in tissue paper, hang in a
cool place, or pack in sawdust.
To
Keep Lemons and Oranges.—Lemons may be kept fresh for weeks
by placing them in a vessel of cold water in a very cool cellar or ice
house. Change the water every day. Oranges may be kept in the same way.
The usual method employed by growers for keeping these fruits is to
wrap each one separately in tissue paper, and put in a cool, dry place.
To
Keep Cranberries.—Put them in water and keep in a cool place
where they will not freeze. Change the water often, and sort out
berries which may have become spoiled. Head for the top of Keeping Fruit
