| Description | Prunus Amygdalus Amara Kernel Oil is the volatile oil obtained from the kernels of the Bitter Almond, Prunus amygdalus var. amara, Rosaceae |
| Chemical Properties | Bitter almond oil (free from hydrogen cyanide) contains benzaldehyde as itsmain component. Benzaldehyde does not occur as such in the plant, but is formed,together with hydrogen cyanide, by the hydrolytic cleavage of the glycoside amygdalin. Amygdalin is present in bitter almonds, the seeds of Prunus dulcis var. amara(DC.) Buchheim, and ripe apricot kernels, Prunus armeniaca L. (Rosaceae).Thepress cake, which remains after removal of the fatty oils, is macerated with waterand left to stand for several hours, after which the “essential oil” is separatedby steam distillation. The crude oil contains 2–4% hydrogen cyanide, whichis removed by washing with alkaline solutions of iron(II) salts. Subsequentredistillation yields an oil free from hydrogen cyanide. It is a colorless to slightlyyellow liquid with an intense, almond-like, cherry aroma and a slightly astringent, mild taste. d2525 1.025–1.065; n20D 1.5350–1.5550; acid value: max. 8; solubility: 1 vol inmax.6 vol 50% ethanol. HCN content: <0.01%; benzaldehyde content by GC: min. 98%. Bitter almond oil is used almost exclusively in natural aroma compositions. |
| Chemical Properties | Bitter almond has an intense, almond-like, cherry aroma with a slightly astringent, moldy taste. The term bitter almondrefers to the essential oil obtained by steam distillation of the partially de-oleated press-cake of kernels from any of the following:bitter almond (P. amygdalus), apricot (P. armeniaca) and peach (P. persica). The kernels from these and other such fruits contain theglucoside amygdalin, which on enzymatic hydrolysis yields benzaldehyde and HCN. The distilled oil must be rendered free of HCN(prussic acid) prior to its marketing as a flavor ingredient. Very little essential oil is currently made exclusively from bitter almondsor other fruit kernels; specially purified benzaldehyde is often used in its place |
| Physical properties | Oil intended for use as a flavor ingredient is treated to remove traces of HCN by precipitationas insoluble calcium ferrocyanide. |
| Definition | Volatile oil from Amygdalin-contg. Prunus species. |
| Essential oil composition | Bitter almond oil is obtained by first cold-expressing the fixed oils from the comminuted kernels, afterwhich the press-cake is macerated in about 10 parts of water for 12 to 20 hours to effect the enzymatic hydrolysis of amygdalin. Themixture is then steam distilled to yield about 0.5 to 0.7% of the essential oil. Bitter almonds are rarely used because the yield of oilis only 0.6%. Apricot kernels yield 1.2% of oil and are the preferred starting material. The major components of the oil are typically97.5% benzaldehyde (bitter almond) and 2% hydrogen cyanide (bitter almond). |
