An aroma chemical profile: Linalool

The small amount of natural Iinalool available is produced from Bois de Rose oils of Brazil and Paraguay and Ho-leaf oil from Taiwan and China. The volume of supply of natural product, however, has been dwarfed by the supply of synthetic product. The demand for linalool cannot be met by the production of natural oils.

We might divide these raw materials roughly into three groups: 1) those that serve as raw materials in the production of isolates, competing head-on with synthetics and including citronella, lemongrass, menthol, and clove leaf; 2) those that can be replaced by synthetic oils, such as anis, rose, fir needle, geranium, citrus oils, sandalwood mint oils, and floral extractives; 3) those that are not threatened by replacements–at least for the present– including cedarwood, eucalyptus, guaiaewood, lavandin, ocotea, petitgrain, patchouli, vetivert, and ylang.

Historical and recent developments of essential oils and aroma chemicals

Our industry is unique because it is concerned with agriculture, chemistry, physiology, bacteriology and other sciences. No other industry, chemical or otherwise, produces such a diversified and great number of individual materials. It is also understandable that these operations require the application of various chemical reactions and analytical procedures. The future of the essential oil-aroma chemical industry can be predicted in two words: Continuous Progress.

Reflections of a Retired Flavorist Before He Forgets: Cocoa

In keeping with today’s irrational demand for natural products and the even more ridiculous activity of our industry, supplying these in ever mom concentrated form, the use of natural amino acids and sugars to obtain a natural reacted end-product plus added pure vanilla, cocoa distillate or extract, and traces of essential oils (such as Bois de Rose for its Iinalool content ) results in quite satisfactory, less expensive and more concentrated “natural coca or chocolate flavors.
