See also:NUTMEG (from " See also:nut," and O. Fr. mugue, See also:musk, See also:Lat. muscus)
, the commercial name of a spice representing the See also:kernel of the See also:seed of Myristica fragrans (fig
.
1), a dioecious See also:evergreen See also:tree, about 5o to 6o ft. high, found See also:wild in the See also:Banda Islands and a few of the neighbouring islands, extending to New See also:Guinea
.
See also:Nutmeg and See also:mace are almost exclusively obtained from the Banda Islands, although the cultivation has been attempted with varying success in See also:Singapore, See also:Penang, See also:Bengal, See also:Reunion, See also:Brazil, See also:French See also:Guiana and the See also:West Indies

Fruit after removal of one-See also:half of the pericarp, showing the dark See also: years after See also:sowing the seed, reach their See also:prime in twenty-five years, and See also:bear for sixty years or longer . Almost the whole See also:surface of the Banda Islands is planted with nutmeg trees, which thrive under the shade of the lofty Canarium See also:commune . In Bencoolen the tree bears all the See also:year See also:round, but the See also:chief See also:harvest takes See also:place in the later months of the year, and a smaller one in See also:April, May and See also:June . The ripe fruit is about 2 in. in See also:diameter, of a rounded See also:pear-shape, and when mature splits into two, exposing a See also:crimson arillus surrounding a single seed (See also:figs . I, 2) . When the fruit is collected the pericarp is first removed; then the arillus is carefully stripped off and dried, in which See also:state it forms the mace of See also:commerce . The seed consists of a thin, hard testa or See also:shell, enclosing a wrinkled kernel, which, when dried, is the nutmeg . The kernel consists n m mainly of the abundant endosperm, which is See also:firm, whitish in See also:colour and marbled with numerous reddish-brown vein-like partitions, into which the inner seed-coat penetrates, forming what is known botanically as ruminated endosperm . To prepare the nutmegs for use, the seed enclosing the kernel is dried at a See also:gentle See also:heat in a drying-See also:house over a smouldering See also:fire for about two months, the seeds being turned every second or third See also:day . When thoroughly dried the shells are broken with a wooden See also:mallet or See also:flat See also:board and the nutmegs picked out and sorted, the smaller and inferior ones being reserved for the expression of the fixed oil which they contain, and which forms the so-called oil of mace . The dried nutmegs are then rubbed over with dry sifted See also:lime.The See also:process of liming, which originated at the See also:time when the Dutch held a See also:monopoly of the See also:trade, was with the view of pre-venting the germination of the seeds, which were formerly immersed for three months in See also:milk of lime for this purpose, and a preference is still manifested in some countries for nutmegs so prepared . It has, however, been shown that this treatment is by no means necessary, since exposure to the See also:sun for a See also:week destroys the vitality of the kernel . Penang nutmegs are never limed . The entire fruit preserved in See also:syrup is used as a sweetmeat in the Dutch See also:East Indies . " Oil of mace," or nutmeg See also:butter, is a solid fatty substance of a reddish-brown colour, obtained by grinding the refuse nutmegs to a See also:fine See also:powder, enclosing it in bags and steaming it over large cauldrons for five or six See also:hours, and then compressing it while still warm between powerful wedges, the brownish fluid which flows out being after-wards allowed to solidify . Nutmegs yield about one-See also:fourth of their See also:weight of this substance . It is partly dissolved by See also:cold See also:alcohol, the See also:remainder being soluble in See also:ether . The latter portion, about to% of • the. weight of the nutmegs, consists chiefly of myristin, which is a See also:compound of myristic See also:acid, C14H2802, with See also:glycerin . The See also:fat which is soluble in alcohol appears to consist, according to See also:Schmidt and See also:Roemer (See also:Arch . Pharnt . [31, xxi . 34-48), of See also:free myristic and stearic acids; the brown colouring See also:matter has not been satisfactorily investigated . Nutmeg butter yields on See also:distillation with See also:water a volatile oil to the extent of about 6 %, consisting almost entirely of a See also:hydrocarbon called myristicene, C[01116, boiling at 165° C . It is accompanied by a small quantity of an oxygenated oil, myristicol, isomeric with carvol, but differing from it in not forming a crystalline compound with hydrosulphuric acid . Mace contains a similar volatile oil, macene, boiling at 16o° C., which is said by Cloez to differ from that of nutmegs in yielding a solid compound when treated with hydrochloric acid See also:gas . The name nutmeg is also applied to other fruits or seeds in different countries . The See also:Jamaica or See also:calabash nutmeg is derived from Monodora Myristica, the Brazilian from Cryptocarya mosclaata, the Peruvian from Laurelia sempervirens, the See also:Madagascar or clove nutmeg from Agathophyllum aromaticum, and the Californian or stinking nutmeg from Torreya Myristica . The cotyledons of Nectandra Puchury were at one time offered in See also:England as nutmegs . |
