Oil, almond

BENZALDEHYDE The precursor for speed. It makes up nearly 100% of bitter almond oil. Not a very popular oil with the DEA. Some hints Benzaldehyde is indispensable for the flavoring industry. It is the flavor in almond extract and synthetic benzaldehyde is used in all cherry flavorings. Also, there is currently a little loophole in the system when it comes to a product called Roasted Cassia Oil . Apparently, some manufacturers take cassia oil and run it through some sort of industrial process to change it into benzaldehyde. No one wanted to tell Strike the particulars of how this was done. But one company chemist gave me some hints (You can get really chatty with some of these guys).

A considerable quantity of oil can be extracted from waste material from shelling and processing plants, eg, the inedible kernels rejected during shelling and fragments of kernels recovered from shells. About 300 t of pecan oil and 300—600 t of English walnut oil are produced aimuaHy from such sources. The oil is refined and used for edible purposes or for the production of soap the cake is used in animal feeds (see Feeds and feed additives). Fmit-pit oils, which closely resemble and are often substituted for almond oil, are produced on a large scale for cosmetic and pharmaceutical purposes (143). For instance, leaves, bark, and pericarp of walnut may be used to manufacture vitamin C, medicines, dyes and tannin materials (144). 

The other significant production method for natural benzaldehyde involves the steam distillation of bitter almond oil which has been derived from the kernels of fmit such as apricots, peaches, cherries, plums, or pmnes. The benzaldehyde product obtained in this fashion is claimed to have a superior flavor profile. The use of peach and apricot pits to produce the more profitable product laettile apparently affects the supply available to natural benzaldehyde producers.

The question whether sanctions are imposed— and which sanctions—when a product is found to fail dmg QC testing is as important as detection of substandard products itself. The present data sets are, however, inadequate for establishing direct links between the findings of QC analysis and the imposition of regulatory sanctions (area E in Figure 4.1). Certain cases have been documented in Venezuela over the past 10 years. For example, 100 products were prohibited, and a laboratory manufacturing almond oil was closed down.

The seed oil is golden yellow, with a nutty odor and a pleasant, although slightly bitter flavor, and has been described as similar to almond oil in consistency and taste (van der Maesen, 2006). 

CyHeO, Mr 106.12, Z />101.3kPa 178.1 °C, d] 1.0415, Wp 1.5463, is the main, characteristic component of bitter almond oil. It occurs in many other essential oils and is a colorless liquid with a bitter almond odor. In the absence of inhibitors, benzaldehyde undergoes autoxidation to perbenzoic acid, which reacts with a second molecule of benzaldehyde to benzoic acid. 

Bitter almond oil (free from hydrogen cyanide) contains benzaldehyde as its main 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. 

Bitter almond oil is used almost exclusively in natural aroma compositions.
