Oil of Cinnamon
Oil of cinnamon is made from the pieces and chips of the bark, it is of a red-yellowish color. Eighty pounds of bark yields about 8 ozs. of oil. It is very stimulating. It is often adulterated with oil of cassia, oil of cassia buds, oil of cherry laurel, and oil of bitter almonds—the latter is a very dangerous mixture.
Cinnamon leaves yield an oil resembling oil of cloves, with which it is often mixed.
The ripe berries of the cinnamon tree yield a volatile oil, similar to oil of juniper, and from the root is obtained camphor.
Cassia oil is obtained from the leaves, buds, or bark. It is of a golden-yellow color, but turns brown with age. It is considered good for influenza.
Cassia buds resemble nails with heads of different size and shape, according to the period of growth when collected.
There is also a kind of wild cinnamon, or cassia, which grows in Cuba, but its taste resembles more that of cloves than of cinnamon.
CLOVES
Interesting History With Illustration Showing Flower, Bud and Fruit—Where Grown and Commercial Uses
Cloves are dried, unopened calyces or flower buds of the clove tree, Caryophyllus aromaticus, a kind of myrtle, a native of the Molucca islands. In commerce they are chiefly distinguished by their place of growth and rank in the following order: Penang, Bencoolen, Amboyna, and Zanzibar. In addition to these there enter into commerce as secondary products, clove stalks and mother cloves, or the dried ripened fruit. The bulk of these secondary products are shipped from Zanzibar.
The clove tree is an evergreen, 15 to 30 ft. high. It has a thin smooth bark and adheres closely to the wood, which is a gray color and of little use. The leaves are 3 to 5 in. long. The upper side and foot-stalk is red, shading to a dark color, while the under surface is green. The flowers grow in small bunches at the extremities of the boughs, very like the flower-buds of the lilac tree, and all are of a delicate purplish color. The calyx is long and forms the seed sack. As the blossoms fade the calyx changes color from yellow to red. If allowed to remain on the tree after this the calyx swells like that of the rose. In this state it loses its pungent properties and is called mother clove, and is practically of no value as a choice spice. The cultivated trees are kept pruned to about 8 or 10 ft. in height.
The harvesting of the flower-buds commences immediately after they assume a bright red color. Such blossoms as can be reached are plucked by hand, while those that grow on the upper branches are beaten down with bamboo poles and caught in clothes spread beneath the trees. They are then dried in the shade or by hanging on hurdles over slow wood fires—they lose about half their weight in the drying process. They are usually finished off in the sun, which gives them a darker color. The quicker they are dried the less the loss of aroma. Good cloves have a strong aromatic smell, a hot, spicy taste and a light brown or tan color. The season for harvesting is from September to March. A 10-year-old tree yields about 20 lbs. of cloves a year, the yield increasing up to 100 lbs. for a 20-year old tree.
Penang cloves are from the Straits Settlements. They are large, plump and of a bright color. Amboyna cloves are not so large as the Penang and are of a dark brown color. Zanzibar cloves are smaller than the Amboyna, a bright reddish color and generally very dry. Pemba cloves are small and dark in color and mostly arrive in a damp condition, and therefore lose weight if kept long.
Cloves have sometimes a portion of their oil extracted, which gives them a pale, thin, shriveled appearance, altho they may be freshened up by rubbing with a little oil or passed off by mixing with good cloves. Cloves that have been tampered with have a good proportion of their heads or knobs off; altho another cause for headless cloves is that they may have been gathered when too ripe.
Pure oil of cloves is almost colorless, with a faint yellow tinge and the strong smell and burning taste of cloves. When old it turns to a reddish brown color. It has a greater specific gravity than water, in which it will sink.
Clove stalks and mother cloves are used in the manufacture of ground cloves and mixed spices. In Brazil the flower-buds of the tree whose bark furnishes cloves cassia are often used as substitutes for true cloves. The clove tree attracts so much moisture that herbage will not grow beneath its branches and the clove of commerce has such an affinity to water that if placed near a vessel of water they will absorb enuf of the moisture in a few hours to appreciably increase their weight. It is said that dealers often take advantage of this to increase the weight of their goods and thus enhance their profits.
A Little Clove History—This spice was well known to the ancients and is mentioned by several Chinese authors as in use under the Han dynasty, B. C. 266 to 220, during which period it was customary for the officers of the court to hold the spice in their mouth before addressing the sovereign, in order that their breath might have an agreeable odor. At this period the clove was called fowl’s tongue spice. In 1265 A. D. the price was 12s per lb. In 1609 a ship of the East India Co., called the Consent, brot 112,000 lbs. to England which was sold at 5s 6d per lb. As was the case with nutmegs, the Dutch attempted to control the business in cloves. With this object in view, they caused all the clove trees to be destroyed except those of the island of Amboyna. The natives of the island were compelled to rear a certain number of plants each year and also to protect the bearing trees. The French, however, found a number of clove trees growing wild in the smaller island, and Poivre, French governor of Mauritius, who obtained the plant from the island of Guebi, introduced the clove tree into that colony in 1770. About 1800 an Arab named Harameli-ben-Selah took some seeds and plants from Boubon to Zanzibar and commenced the cultivation of cloves in that country. The word clove is derived from the Latin clavus nail, Spanish clavo and French clou, owing its nail-like appearance.
GINGER
Used as a Spice by the Early Greeks and Romans—Plant a Native of Asia and Grew Wild in Mexico and Africa
As a spice, ginger was used among the early Greeks and Romans, who appear to have received it by way of the Red sea, inasmuch as they considered it to be a production of southern Arabia. In the list of imports from the Red sea into Alexandra which, in the 2nd century of our era, were then liable to the Roman fiscal duty, ginger occurs among other Indian spices. It appears in the tariff of duties levied at Acre in Palestine, about 1173, in that of Barcelona in 1221, Marseilles in 1228 and Paris 1296. It was known in England before the Norman conquest, being frequently named in the Anglo-Saxon leech-books of the 11th century as well as in the Welsh “Physicians of Myddvai.” During the 13th and 14th centuries, it was, next to pepper, the commonest of spices, costing on an average 1s 7d per lb., or about the price of a sheep. Three kinds of ginger were known to Italian merchants about the 14th century: (1) Belledi of Baladi, an Arabic name which applied to ginger would signify country, wild, and denotes common ginger; (2) Columbonio, which refers to Columbuno, Kolam or Quilon, a port in Travanore, frequently referred to in the middle ages; (3) Micchino, which denotes brot from or by way of Mecca. Marco Polo saw it in India and China, 1230–1239. John of Montecorvino, a missionary friar, who visited India in 1290, gives a description of the plant and refers to the root being dug up and transplanted. Nicolo de Conti, a Venetian merchant, early in the 15th century describes the plant and a collection of roots he saw in India. The Venetians received it by way of Egypt, and superior kinds from India overland by the Black sea. Ginger was introduced into America by Francisco de Mondoca, who took it from the East Indies to New Spain. It was shipped for commercial purposes from the islands of St. Domingo in 1585, and from Barbadoes in 1654.
Ginger is the dried, knotty fibrous rhizomes or tubers—“races” or “hands” as they are called from their irregular, palmate form—of the ginger plant (zinziber officinale) the real roots being the thin fibers that branch off from the rhizomes.
The plant is a native of Asia, but also found growing wild in Mexico and East Africa. It is a reed-like biennial plant, not unlike the iris or flag in appearance. The leaves are long, similar to those of maize, growing alternate on a stem 3 to 4 ft. high. The flowers are borne on a separate stem, 6 to 12 in. high; they are yellow or blue, according to the quality of the soil in which they have been grown. The plant which produces the yellow flower and best ginger is grown on rich, deep, virgin soil; the other comes from poorer ground. Ginger is propagated by pieces of the rhizome being planted in March. The flowers appear about September, after they have withered and seeded. The roots are dug up about January. When left too long in the ground, the rhizomes become very fibrous, if taken up too soon they are tender and succulent, so much so that they cannot be made sufficiently dry to render them fit for export in the usual commercial form. They are therefore preserved in sugar. The rhizomes, besides being classed as “yellow” or “blue,” are also divided into “plant,” (being the rhizomes from plants of the same season’s growth), and “ratoon” which are rhizomes left in the ground from the previous harvest.
Ginger is known in commerce in two distinct forms, termed respectively as coated or uncoated ginger,—as having or wanting the epidermis. For the coated ginger, the races of hands, after being dug up, are thoroly washed to free them from all the adhering earth. They are then laid on a canvas or cement floor, outdoors, to dry by the heat of the sun. At night they are taken indoors. It takes from 6 to 8 days to thoroly dry them. They are then ready for shipment. In damp weather they are artificially dried by an evaporator. In this form ginger presents a brown, more or less wrinkled or straited, surface, and when broken up shows a dark brownish fracture, hard, and sometimes horney and resinous. For the uncoated ginger the fresh-dug rhizomes, after being washed, are soaked in water for some time and then peeled or scraped—a most delicate operation requiring the hand of an expert. Owing to the peculiar formation of the races, no machine has yet been invented that will do the work satisfactorily. The outer rind or skin is deftly taken off by means of a common knife, so as not to injure the inner root, as a loss of the pungent volatile oil, to which ginger owes its value, would follow and thus impair its commercial worth. After being peeled the races are soaked in water over night. In the morning they are again washed, cleaned and weighed, and then dried in the same manner as coated ginger.
It requires 3 lbs. of green root to make 1 lb. of dry root. The purer the water the whiter the ginger. Sometimes lime juice is added to the wash water, which gives a whiter root, but as lime juice contains sugar, it prevents thoro drying and mildew follows. Ginger is often subjected to a system of bleaching, or by immersion for a short time in a solution of chlorinated lime. The white-washed appearance which much of the ginger has is due to the fact of its being washed in whiting and water or even coated with sulphate of lime. Uncoated ginger varies from single joints an inch or less to flattish, irregularly branched pieces of several joints, the races of hands, and from 3 to 4 in. long. Each race has a depression on the summit showing the former attachment of a leafy stem. The color, when not white-washed, is a pale buff. It is somewhat rough, breaking with a short, mealy fracture, and presenting on the surface of the broken parts numerous short or bristly fibers.
The best ginger grown comes from Jamaica. It is of a superior strength, fine flavor and a light, handsome color. A peculiar trade custom prevails in Jamaica with regard to ginger, which is not sold by weight or measure but by the “heap,” and the size of the heap governs the price and is an indication, to a certain extent, of the quality and quantity of the crop. If the heap is small, the price is high; if the heap is large, then the price is lower. If the races or hands, are finely shaped and large, there are fewer in the heap; if small, dark and mealy, the heap is made larger.
The next best quality is Borneo or Cochin ginger, which closely resembles in appearance the Jamaica. It is not, however, so carefully prepared.
African ginger, also termed Bombay or Calcutta, from the ports of shipment, is darker in color, has a coarser appearance, a harsher flavor and inferior aroma to either of the above, but contains a greater amount of oleoresin than they do and is very pungent. It is largely used for making ginger beer, essences, extracts, etc.
Leaf ginger is ginger that has been sliced into thin flakes.
Green ginger root, is that which has not undergone any process of cleaning beyond freeing it from the earth adhering. Imported in casks and used by wine makers, preservers, etc.
Spent-ginger is whole ginger that has once been used, then fixed up to resemble good ginger and sold whole or ground. It does not possess a single one of the valuable properties of genuine ginger.
China ginger is not imported in a dried state, the rhizomes being too tender and succulent to thoroly dry for export. It is preserved or candied. For preserving, the rhizomes are first scalded, then washed in cold water and peeled, then boiled in pans for 2 or 3 hours; then transferred to copper pans and boiled for 2 hours in a mixture of sugar and water—just sufficient water to cover the roots, 5 lbs. of sugar to 10 lbs. of ginger, the roots having been pierced with a sharp instrument to enable the sugar to soak into them. After boiling the ginger is put into large jars and stands for several days, when it is again boiled in sugar and water in the same quantities. After it has become cold it is packed in jars or tins for export. To crystallize, the same process is gone thru, only in the final boiling it is boiled until the sugar become dry.
The Chinese season for preserving ginger is from July to October. It is nearly all prepared in Canton and Hongkong. A kind known as Ng Mai Keunig is preserved in Swaton, from Alpina galanga, but it is not like the Canton or Hankou ginger and is only made for native consumption, to be used medicinally or for cooking. Some of it goes to the Straits Settlement, but none to Hongkong. Jamaica preserved ginger is mostly put up in glass bottles. The uses of ginger are too well known to need repeating.
MUSTARD
Well Known to the Ancients, but More in a Medicinal Way—How Cultivated and Prepared for Commercial Uses
Mustard was well known to the ancients, but more in a medicinal way than dietetic. From an edict of Diocletian, 30 A. D., in which it is mentioned along with alimentary substances, we must suppose it was then regarded as a condiment, at least in the eastern parts of the Roman empire. In Europe, during the middle ages, mustard was a valued accompaniment to food, especially with the salted meats which constituted a large portion of the diet of our ancestors during the winter. In the Welsh “Meddygon Myddrai” of the 13th century, a paragraph is devoted to the “Virtues of Mustard.” In household accounts of the 13th and 14th centuries, mustard is of constant occurrence; it was then cultivated in England, but not extensively. The price of the seed between 1285 and 1340 varied from 1s 3d to 6s 8d per quarter (21 lbs.), but between 1347 and 1376 it was as high as 15s and 16s. In the accounts of the Abbey of St. Germain des Pres in Paris, 800 A. D., mustard is specially mentioned as a regular part of the revenue of the convent lands.
The essential oil of mustard was first noticed in 1660 by Nicolas le Febre and more distinctly in 1732 by Boerharroe.
The word mustard comes from the Italian, murtard, which is derived from the Latin must-um, unfermented grape juice, with which the Italians formerly mixed ground mustard. The Athenians called it napy; while the Hellenistic name was sinapi, or sinapy, whence the Latin sinapi, or sinapis, from which is derived the German word senf. Hippocrates used mustard in medicine under the name of Vanuit. The dark seed, which comes from Trieste, Austria, is called Trieste mustard. Spoken of by Theophnastus, Galin and others. What is called French mustard, German mustard, etc., is made of the dressings mixed with vinegar, garlic and other spices and flavoring musterial. The form in which table mustard is now sold dates from 1720, about which time Mrs. Clements, of Durham, Eng., hit on the idea of grinding the seed in a mill and sifting the flour from the husk. This bright yellow farina rapidly attained wide popularity. The fame of “Durham Mustard” was spread far and wide, Mrs. Clements traveling to London and principal cities twice a year taking orders.
There are two species of mustard plants from which ground mustard is made. The sinapes alba, white or yellow mustard, and sinapes nigra, brown or black mustard, is the mustard plant spoken of in Luke XIII, 19. They are annual herbs, three to 6 ft. high, with lyrate leaves, yellow flowers, and slender pods, from one to four inches long, containing a single row of roundish seeds.
One of the peculiarities incident to the cultivation of mustard is the fact that two crops of mustard cannot be raised on the same ground in succession. Another variety is sinapes arvenus, or wild mustard, called charlock and used for adulterating; the Sarepta, the black seed of the sinapes juncea, from the East Indies, is used for the same purpose. Sarepta is called from a city of that name in Russia, in the government of Saratov.
The brown or black variety is sown in January and the yellow or white in March, the seed being sown broadcast and harvested in August. A reaper is used, cutting the stalks and throwing them in bunches, where they are left to cure until October. They are now thoroly dry and are taken to a convenient place, spread out upon sheets of canvas and rolled with a heavy roller. The stalks and empty pods are then raked off, and the chaff and seeds remaining are run thru a fanning machine, after which process they are ready to sack and market.
There are two processes in use in making ground mustard. In the first, the seeds, white or black, or mixed, are ground to powder and then put thru an elaborate course of siftings. The product left after the first sifting is called “dressings” and that which passes thru is pure mustard flour. This mustard flour is again run thru a finer sieve, and so on until the required fineness is obtained. From the dressings left after the different sievings, the essential oil of mustard is expressed.
In the other method, the oil is first extracted from the seeds by hydraulic pressure, which leaves a sort of cake. This cake is then broken up and pounded in a mortar. It is then sifted, that going thru the sieve being a kind of bolted mustard flour. The remaining bran is then mixed with an equal quantity of wheat flour, one per cent of cayenne and sufficient turmeric to give the proper color. This is pounded and treated as before, the process being continued until there is no bran left. Then all the different siftings are mixed together, giving a mixture of about equal proportions of mustard and wheat flour, with the cayenne and turmeric added in proper quantities.
The peculiar pungency and odor, to which mustard owes much of its value, are due to an essential oil developed by the action of water on two chemical substances contained in black mustard seed; one called sinigrin and the other myrosin. The latter substance in the presence of water acts as a sort of ferment on the sinigrin, and it is worthy of remark that this reaction does not take place in the presence of boiling water and, therefore, it is not proper to use very hot water in the preparation of mustard, cold water only should be used. White mustard seed contains in the place of sinigrin a peculiar acrid substance called sinalbin and also a trace of myrosin, therefore, it possesses very little pungency and it produces a larger percentage of flour than the black. The proper blending of these two seeds is necessary to the production of the best mustard, as the white has the peculiar ferment within it which develops to the highest degree the flavor of the black.
The reason for mixing wheat flour, rice flour or other farina with pure mustard flour is, that owing to the large amount of oil contained in the latter it will not keep long, but turns rancid, ferments and cakes; the added farinas by absorbing a portion of the oil retards fermentation, decomposition and rancidity. They should not be looked upon as adulterants, unless added in too great quantities, and the price of the mustard should be in proportion to the added absorbents.
A mean form of adulteration is to mix gypsum and chrome yellow with the ground mustard seed.
If upon the addition of a small quantity of iodine to ground mustard it turns blue, it shows that starch is present. The ammonia test will show the presence of turmeric. Every manufacturer has his own particular formula, and consequently there are many different qualities, both in the pure mustard and the compounds. One is composed of 37 per cent brown and 50 per cent white mustard flour, 10 per cent of rice flour, 3 per cent of black pepper, a little Chili pepper and ginger.
Pure mustard oil, as pressed from the seed, is not pungent and will not blister unless mixed with water.
The English mustard seed is the best in the world. Of this class 4,995,800 lbs. of seed and 1,307,202 lbs. of flour were imported during the year 1908. Mustard seed and flour from Italy is known as Trieste. In the Lompoe valley, California, some 2,500 acres are under mustard cultivation, and a small quantity is also grown in Kentucky.
The uses of mustard are too well known to need recapitulation. D. S. F. means double superfine.
NUTMEG AND MACE
Where the Nutmeg Tree Grows—Yield of Nuts and Mace and How Prepared for the Market—Uses in Commerce
The nutmeg tree, known to botanists as Myristica frangrans (sweet smelling) is a native of the Malay archipelago. The tree, which in the Banda isles grows to the height of 50 to 60 ft., and in the Straits to 30 to 40 ft., resembles the pear tree in the shape of its leaves and fruit. Its flowers are like those of the lily of the valley in form and size, but are pale yellow and exceedingly fragrant. There are male and female flowers, the nutmegs being obtained from the latter. It is only when the tree is about 6 or 8 years old that the female tree can be distinguished from the male, and of the latter only a few are allowed to remain for fertilizing purposes, the rest being cut down. The nutmeg tree continues to yield from 70 to 80 years after reaching maturity (8 years). Each tree on an average will produce 10 lbs. of nutmegs and 1½ lbs. of mace annually. The fruit is yellowish, edible drupe, about the size of a peach; it splits into halves when at maturity—about 9 months from the time of blossoming—exposing a single seed with a thin, hard shell, surrounded by a fibrous substance of a crimson color, which, when dried and shelled becomes the nutmeg. The young drupes, when young and tender, are often preserved like jam and are considered the most aromatic and delicious of conserves. Altho the nutmeg tree has ripe fruit upon it at all seasons, there are three principal periods of harvesting, viz: July, when the fruit is most abundant, though it yields thin mace; November, when the mace is thicker, though the nutmegs are smaller, and March, when both mace and nutmegs reach their greatest perfection—but as this season is dry the production is not great.
The usual method of gathering in the Straits is to collect the ripe nuts that have fallen on the ground. In the Banda islands, the fruits are gathered in small, neatly-made, oval bamboo baskets—holding about 3 fruit—at the end of a long bamboo stick, which prevents bruising, the baskets being opened for about half their length on one side, and furnished with two small prongs projecting from the top, by which the fruit stalk is broken, the fruit falling into the basket. After the pulp—which is about ½-in. thick, whitish in color, and tough like candied peel—has been removed the mace is stripped off by hand. The shell of the fruit is very hard and cannot be broken without injury to the kernel. To overcome this they are put into receptacles with fine mesh bottoms, and dried over a slow fire—being turned from time to time—until the kernel rattles freely in the shell, a process which takes about 6 or 8 weeks. This also kills any weevil which may be at work in them. They are then carefully cracked by placing them on a sort of drumhead made of raw-hide and striking them with a board or mallet, when the shells fly off into pieces. Great caution is needed in shelling, for if too hard a blow be struck it makes a black spot on the nutmeg, which affects its value considerably. After being steeped in salt water several times and again dried they are sorted according to size and soundness—130 to 140 to the pound are the lowest priced, 75 to 80 the highest, and larger nuts are sold at special prices. The sorting is done by hand, and nothing but sound, perfect nuts are supposed to be shipped. The broken and wormy ones are used in manufacturing “nutmeg butter,” or, as it is commonly but erroneously called, “mace oil.” They are now limed. There are two methods of liming in vogue—the dry and the wet. In the dry process, the nuts have dry lime powder rubbed over them, either by hand or shaking in barrels. In the wet process, the nuts are put into newly-slacked lime and then spread out to dry, or they are dipped into a kind of lime-pickle, thick as syrup, made of calcined-shells and salt water. After being covered with this mixture they are dried. The process of liming originated with the Dutch, with a view to preventing the germinating of the seeds, for which purpose they were formerly immersed for three months in milk of lime. Again it is claimed that liming preserves the nuts against the attacks of maggots and a particular kind or beetle by stopping up their breathing and chewing apparatus. A preference is still manifested for limed nutmegs.
As nutmegs are now seldom shipped by sailing vessels, but by steamers, thus saving the long-time voyage, there is no reason why they should not come unlimed, and then the differences in their natural complexions and range of variations would become familiar and easily recognized. The liming process hides many imperfect or corky nuts; nuts which have been riddled with worm holes are “stopped” with a paste made of flour, oil and nutmeg powder and then mixed with the sound ones. Occasionally this paste is moulded into false nutmegs. Besides this, nutmegs are frequently robbed of part of their essential oil by distillation in alcohol—a process called “sweating”—and yet sold as entire nuts. A small quantity of boracic acid will accomplish the same purpose as lime, and Paris white and barytes will serve to mask the identity as well as the defects. A good nutmeg should have no worm-holes, be full of oil and cut firm like a piece of wood, and if a pin is thrust into one the oil should ooze out on its being withdrawn.
The Penang nutmegs, which are generally not limed, are considered the best, altho some prefer the Banda or Batavia, and after these the Singapore. There is also a demand for an elliptical-shaped nutmeg of rank flavor, first called long nutmegs, but now known as Macassars. Another kind of nutmeg from New Guinea, and known in Germany as “horse nutmeg,” is from the species Myristica Argentea. It is of a long and narrow shape. In these the arellus or mace furrows are less marked and their odor is not so delicate as that of the true nutmeg.
There are many kinds of wild or inferior nutmegs, such as: American Jamaica, or calabash nutmeg (M. monodora), of the custard-apple family, bearing a large pulpy fruit containing aromatic seeds. Brazilian nutmeg (cryptocarya moschata) a tree of the laurel family, producing nutmegs of an inferior quality. The nut is longer than the true species and is sold under the name of long nutmeg. California nutmeg, a tree of the pine family, called also stinking nutmeg or stinking yew, from the disagreeable odor of the leaves and wood when bruised and burned, and yielding a fruit resembling true nutmegs. Clove nutmeg, a Madagascar tree of the laurel family, the fruit a pungent kernel resembling the true nutmeg and used as a spice. Peruvian nutmeg, a large tree of the monimiad family, yielding an aromatic fruit. From Borneo a wild, soapy nutmeg and mace (M. fatua) are often palmed off as the true kinds. There is also the Sante Fe nutmeg (Motoba) from Columbia, S. A., and Ackaway nutmeg, a spice grown in Guiana, the fruit of Acrodiclidum camard. Another species, the M. sebefira, is a common tree in the forests of Guiana, north Brazil, and up into Panama. It is utilized principally for the oil extracted from the nuts, obtained by macerating them in water, the oil rising to the surface, and as it cools skimmed off. Ackawi nutmegs, used mainly as a cure for diarrahoea and colic. All these, while resembling somewhat the true nutmegs and sometimes foisted on dealers, are of very little real value.
