Advances in the Chemistry of Nitriles and Amides
By: Mark Erman
Nitriles and amides represent two important families of organic compounds containing respectively, a CN or a CONR1R2 moiety. Their chemistries are very much intertwined because either family can serve as a feedstock for the other.

A Unique Mentha Aquatica Mint For Flavor
By: Donald Roberts and Anne Plotto
The essential oil from peppermint, Mentha x piperita L., is one of the most widely used oils by the flavor industry for mint flavoring. However, abundant literature and experts’ observations report the varying composition and organoleptic profiles of peppermint oils according to the region of production, climatic variation and harvest date.1-3

Comparative Investigations Of The Essential Oil And Volatiles Of Spearmint
By: Leopold Jirovetz,Gerhard Buchbauer, Manochehr …
Essential oils and extracts of Mentha spicata have long been of high importance in food-product, perfumery and cosmetic applications due to their intense, pleasant, clear-fresh odor. In addition to this species of the Labiatae family, Mentha piperita L. (peppermint) and Mentha arvensis L. (cornmint) are also used extensively.8

New Technologies For The High-Speed Characterization and Analysis Of Essential Oils
By: Tincuta Veriotti, Megan McGuigan and Richard S…
Dramatic reductions in characterization and analysis times for essential oils were achieved using high speed gas chromatography (HSGC) and time-of-flight mass spectrometry (TOFMS). High-speed separations were achieved with relatively short capillary separation columns operated with high carrier-gas flow rates and fast temperature programming. Unique features of TOFMS include high spectral acquisition rates and spectral continuity (constant ion-abundance ratios across chromatographic peak profile).

Solving Quality Problems In Several Flavor Aroma Chemicals
By: Michael Zviely, Reuven Giger, Elias Abushkara,…
The confusion in the interpretation of some aroma chemicals’ molecular structures causes confusion among the users of these products. Several important cases, including keto-enol tautomerisation of alpha-diketones, isomerisation of alpha-angelica lactone, and the exact substitution pattern of pyrazines, will be discussed. The analytical methods used to unravel the correct molecular structures were GC, GCMS and 15N-NMR spectroscopy, and particularly polarization-transfer for sensitivity enhancement (INEPT), and 2D-correlation techniques.

Technology Decisions Challenging the Flavor and Fragrance Industry
By: Nelson, Kate Nelson and Dave Josephson
If there is one thing that successful technology companies have in common it is marketing and public relations. One can hardly read a business-oriented magazine today without seeing either a technology advertisement or self promoting article. But how is a layman to separate fact from fiction?

Riding The Citrus Trail: When Is A Mandarin A Tangerine?
By: Daemmon Reeve, RC Treatt, and David Arthur
In the second installment of articles looking at the origins and development of fruits and their flavoring derivatives, Daemmon Reeve and David Arthur investigate mandarins and tangerines. Today, there are literally hundreds of commercially recognized varieties of mandarin and tangerine in existence worldwide.
