Pimenta Oil химические свойства, назначение, производство
Химические свойства
Pimento oils (allspice oil) are derived from pimento fruits and leaves. Pimento
berry oil is obtained by steam distillation of the dried, fully grown, unripe, berrylike
fruits of the pimento shrub, Pimenta dioica (L.) Merr. (Myrtaceae), growing
in the islands of the West Indies and Central America. The main producer of the
oils is Jamaica. Pimento berry oil is a pale yellow to brown liquid with a spicy odor,
reminiscent of eugenol.
d2020 1.027–1.048; n20D 1.5250–1.5400; α20D ?5 ° to 0 °; solubility: 1 vol in 2 vol of
70% ethanol at 20 °C; phenol content: min. 65%.
Themajor components of pimento oils are eugenol (up to 75%), 1,8-cineole, and
caryophyllene. Distillation of the leaves gives an oil that has an even
higher content of eugenol (80–90%). Annual production of leaf oil exceeds that of the berry oil.
Pimento oils, similar to the spice, are used mainly in the food industry, as well
as in perfume compositions for creating spicy, clove-like notes.
