Coconut. The coconuts which are consumed in the United States are mostly imported. It is estimated that three hundred thousand coconut trees (Cocos nucifera L.) have been planted in Florida, and from 15 to 20 percent of them are already in bearing. The common name of the tree is the coconut palm. The fruit of the coconut palm is used for many purposes. The immature nuts are often used medicinally, forming the base of a valuable ointment for external use. The jelly which lines the shell of the more mature nut furnishes a food product of great delicacy and high nutritive value. The milk of the coconut is itself highly esteemed as a delicious article of food. Grated coconut is one of the basic constituents of that familiar condimental substance, East Indian curry. Coconut oil is a very highly edible fat from which a butter is made. The fat itself is valuable for cooking purposes. The composition of the coconut is shown in the following table: The solid edible portion of the nut is highly oleaginous and contains also a considerable quantity of starch and sugar. Coconut milk is much poorer in nutrients than cow's milk, containing over 92 percent of water, only .4 percent of protein, and only 1.5 percent of fat. The carbohydrates contained therein are chiefly sugars. Filberts. The term filbert, according to some etymologists, is a corruption of the term "full beard," and is so named on account of its having many long beards or husks. The filbert is the fruit of the cultivated hazel tree (Corylus avellana L.). The nut contains a kernel having a pleasant taste and is quite oily and nutritious. It is not cultivated to any extent in this country where we rely principally upon the wild hazel for the hazelnut. The composition of the filbert is shown in the following table (edible portion, 47.9; refuse, 52.1): The filbert is produced in large quantities on the Asiatic shore of the Black The region of Trebizond is the most prolific source of the filbert. Sea. Hazelnut. The hazelnut grows on a small tree or large shrub (Corylus avellana L.). The species which grows wild in the United States is known chiefly as Corylus america Walt. It is from this shrub that the common wild hazelnut is obtained. There is also another variety grown in this country, Corylus rostrata Ait. The hazelnut is a small, nutritious, and palatable nut of a brown color and grows over a very large area of the United States, especially in the northern part of the country. It is quite an article of commerce, but is not cultivated to any great extent. The cultivated variety, as has already been stated, is known as the filbert. Hickory-nut. The hickory-nut is another one of the nuts which sometimes is classed with walnuts and grows very extensively wild throughout the United States, having the same geological distribution as the walnut and butternut. The hickory tree (Hicoria ovata (Mill.) Britton) produces a nut of highest quality. On account of the character of the bark, which becomes detached and often widely separated from the trunk, it is known as the shagbark or shellbark hickory. Another variety of the hickory tree is known as the pignut (Carya glabra). The nut produced by this tree is much less prized than the other hickories, often containing a sufficient amount of tannin to make it distinctly bitter. The wood of the hickory is very tough and elastic and is used extensively in the manufacture of spokes for wagon-wheels, axe-handles, etc. The young hickory trees grow thickly together and have a slender reed-like growth. They are used extensively in the manufacture of hoop-poles. The hickory has suffered from the advance of the farmer much in the same manner as the walnut and other valuable timber trees. The original trees have almost entirely disappeared. The young trees grow vigorously and in a few years will bear nuts, and in some localities the care and cultivation of the wild tree has been established for the purpose of securing new forests of nut-bearing trees. The hickory-nut is even more highly prized for eating purposes than the butternut and walnut, but should be eaten under the same conditions, namely, before the passing of the first winter after their production. They, also, on account of their high content of oil, tend to become rancid when they are kept through the warm summer. Composition of the Dry Hickory-nut.-Edible portion, 37.8; refuse, 62.2. Peanuts. The peanut is a widely cultivated plant. It grows extensively in the United States, and is especially regarded as a crop of high value in North Carolina and Virginia. Very large quantities of peanuts are grown in Senegal, in Algiers, in Egypt, and in many other localities. The pod containing the seed grows underground, but is not a part of the roots, properly so-called. The pods are attached by a slender stems to the stalk of the peanut. The pod of the peanut matures underground, and it may, therefore, be regarded as the seed of the plant, entering and maturing underground. The seeds are immediately covered by a soft envelope and then by several similar coverings. For edible purposes they are much improved by roasting, which gives them an aromatic, nutty flavor which is much. admired. A striking illustration of the peanut is shown in the accompanying colored plate. Peanuts are used as food both directly, as after roasting, and indirectly, by the expression of oil, which after proper refining is considered of high value for edible purposes. The oil of the peanut forms an edible oil of rich flavor, pleasant taste, and high nutritive value. It is used, either alone or mixed with other edible oils, notably with olive oil for table purposes and for the making of salad dressing. The residue of the pressings for peanut oil are highly valued as a cattle food, containing large quantities of nitrogenous nutriment, and also as a manure. The composition of the peanut varies greatly in different localities. Its chief value as a food material lies in the high percentage of protein it contains and the high percentage of fat. The composition of the typical hulled peanut is shown in the following table: Only the blossoms which form on the lower part of the stalk produce the fruit, since it is necessary that the long stem should strike the earth and the young fruit penetrate to the depth of from five to six centimeters in order that the fruit may mature. This method of penetrating the earth is shown very well in the colored figure already mentioned. |
