Fructus vel Semen Cymini; Cumin or Cummin[1258] Fruits, Cummin Seeds; F. Graines de Cumin; G. Mutterkümmel, Kreuzkümmel, Langer oder Römischer Kümmel, Mohrenkümmel.
Botanical Origin.—Cuminum Cyminum L., a small annual plant, indigenous to the upper regions of the Nile, but carried at an early period by cultivation to Arabia, India and China, as well as to the countries bordering the Mediterranean. The fruits of the plant ripen as far north as Southern Norway; but in Europe, Sicily and Malta alone produce them in quantity.
History—Cumin was well known to the ancients; it is alluded to by the Hebrew prophet Isaiah,[1259] and is mentioned in the gospel of Matthew[1260] as one of the minor titheable productions of the Holy Land. Under the name Κύμινον, it is commended for its agreeable taste by Dioscorides, in whose day it was produced on the coasts of Asia Minor and Southern Italy. It is named as Cuminum by Horace and Persius; Scribonius Largus, in the first century of our era, mentions Cuminum æthiopicum, silvaticum and thebaicum.
During the middle ages, cumin was one of the spices in most common use. Thus in a.d. 716, an annual provision of 150 lb. of cumin for the monastery of Corbie in Normandy, was not thought too large a supply.[1261] Edrisi mentioned cumin as a product of Morocco ([see article Fructus Carui, p. 305]), Algeria and Tunisia. It was in frequent use in England, its average price between 1264 and 1400 being a little over 2d. per lb.[1262] Cumin is enumerated in the Liber albus[1263] of the city of London, compiled in 1419, among the merchandize on which the king levied the impost called scavage. It is mentioned[1264] in 1453 as one of the articles of which the Grocers’ Company had the weighing and oversight, and was classed in 1484 in the same way in the German warehouse in Venice.[1265]
Description—The fruit, the colour of which is brown, has the usual structure of the order; it is of an elongated ovoid form, tapering towards each end, and somewhat laterally compressed. The mericarps, which do not readily separate from the carpophore, are about ¼ of an inch in length and ⅒ of an inch in greatest breadth. Each has 5 primary ridges which are filiform, and scabrous or muriculate, and 4 secondary covered with rough hairs. Between the primary ridges is a single elongated vitta, and 2 vittæ occur on the commissural surface. A transverse section of the seed shows a reniform outline. There is a form of C. Cyminum in cultivation, the fruit of which is perfectly glabrous.
Cumin has a strong aromatic taste and smell, far less agreeable than that of caraway.
Microscopic Structure—The hairs are rather brittle, sometimes ½ mm. in length, formed of cells springing from the epidermis. The larger consists of groups of cells, vertically or laterally combined, and enclosed by a common envelope; the smaller of but a single cell ending in a rounded point. The whole pericarp is rich in tannic matter, striking with salts of iron a dark greenish colour.
The tissue of the seed is loaded with colourless drops of a fatty oil; the vittæ with a yellowish-brown essential oil. But the most striking contents of the parenchyme of the albumen consist of transparent, colourless, spherical grains, 7 to 5 mkm. in diameter, several of which are enclosed in each cell. Under a high magnifying power, they show a central cavity with a series of concentric layers around it, frequently traversed by radial clefts. Examined in polarized light, these grains display exactly the same cross as is seen in granules of starch, although their behaviour with chemical tests at once proves that they are by no means that substance; in fact iodine does not render them blue, but intensely brown. Grains of the same character, assuming sometimes a crystalloid form, occur in most umbelliferous fruits, and in many seeds of other orders. All these bodies are composed of albuminous and fatty matters; the more crystalloid form as met with in the seeds of Ricinus and in the fruit of parsley, is the body called by Hartig Aleuron.
Chemical Composition—Cumin fruits yielded to Bley (1829) 7 per cent. of fat oil, 13 per cent. of resin (?), 8 of mucilage and gum, 15 of albuminous matter, and a large amount of malates. Their peculiar, strong, aromatic smell and taste, depend on the essential oil of which they afford as much as 4 per cent. It contains about 56 per cent. of
Cuminol (or Cuminaldehyde),
