Organoleptic Characteristics of Flavor Materials: November December 2006

Advancements in the Flavor Industry. When I started in the flavor industry, a flavor project basically was a request to compound an artificial flavor. The newly established FEMA or GRAS lists were very limited and initially populated under a grandfather clause. Natural ingredients were limited to citrus, floral and mint oils, as well as other natural botanicals and extractives.

Cyclodextrin-Complexed Acetal as an Acetaldehyde Generator

The fixation and stabilization of acetaldehyde both in the physical and chemical sense have long been the subject of many attempts, described in papers and patents, to provide fresh fruit flavors for the food industry.

Chemical Structures

Aldehydes and Acetals - Part 1

Application as flavor and fragrance ingredients.

850x425-Citrus2

Flavor Bites: Acetal

With a similar odor profile to acetaldehyde, acetal’s odor is less pungent and adds freshness to a wide variety of profiles, especially juicy orange flavors.

Acetals and Ketals of 3β, 4β-caranediol-New Odoriferous Compounds from (+)-3-carene

In summary, it is noteworthy that the odor characteristics of acetals and ketals of bicyclic terpenic diols have been absent in the literature. Our discovery of interesting odors of ketals of (+)-3β,4β-caranediol indicates further potential possibilities of synthesis of new odoriferous compounds in the series of bicyclic terpenic diols.

6-Methoxy-2,6-Dimethylheptanal

Use in fragrance compositions

Flavor Bites: Dimethyl trisulfide

The profile of the dimethyl sulfide series of chemicals changes with increasing molecular weight, ranging from jammy to meaty. Additionally, there are dramatic variations in strengths, which can be used in vegetable, savory and dairy flavors.

1,1-Dimethoxy-2,2,5-trimethyl-4-hexene: The Grapefruit Acetal

Chemistry and application in fragrance.

Methyl 2,4-dihydroxy-3,6-dimethylbenzoate

Chemistry and application in fragrance.

2,5-Dimethylpyrazine has a roasted, peanut-like flavor that makes it an excellent fit for roasted nut flavors such as hazelnut, peanut and walnut.

Flavor Bites: 2,5-Dimethylpyrazine

This chemical is compatible with a very wide range of flavor types and works especially harmoniously with trimethyl pyrazine.

Flavor Bites: Dimethyl Sulfide

Use in vegetable, fruit, dairy, brown, fermented, and seafood and meat flavors

3,6-Dimethyl Octan-3-ol

A profile: 3,6-Dimethyl octan-3-ol. Thus is the history of 3,6-dimethyl octan-3-ol and its chemical evolution over forty years of changes in the flavor and fragrance industry. One wonders what might have been the fate of AR-1 if synthetic linalool had not been made available from the vitamin intermediate stream.

Flavor Bites: 2,5-Dimethyl 3-(2H)-furanone

This hidden gem works well in fruit categories and adds interest to any heated flavor category.

Dimethyl disulfide is useful in all brown flavors but especially interesting in cocoa flavors.

Dimethyl Disulfide in Savory, Brown and Nut Flavors

The rather unpleasant and putrid profile of dimethyl disulfide can play an interesting role in quite a number of flavors, just not in raspberry.

Flavor Bites: 3,5-Dimethyl Cyclopentane-1,2-Dione

Use levels for aroma and taste effects in brown, nut, savory, fruit and fermented flavors.

Synthesis and Odor Characteristics of New Gem-Dimethylcyclohexane Derivatives

Searching for cyclic analogs of the insect juvenile hormones, we synthesized a series of new compounds containing the cyclogeraniolene system. This system can be considered as a cyclic form of acyclic terpenes, such as dihydrocitronellol, dihydrogeraniol, and menthocitronellol. The isoprenoid chain in these compounds is rolled to form the cyclohexane ring by connection of the carbon atoms C-7 and C-10. As compared with the classical cyclic systems of the cyclogeraniol type, the compounds obtained by us contain the gem-dimethyl groups in the 3-position in relation to a chain with the functional group.

Flavor Bites: (E)-2-(3,7-Dimethyl 2,6-octadienyl) cyclopentanone

Overall, this quite complex chemical assumes a surprised resemblance to natural apricots.

Bacon flavors can be achieved with ten ppm of 2,6-dimethyl pyridine to give a burnt note.

Flavor Bites: 2,6-Dimethyl Pyridine in Savory, Nut, Brown and other Flavors

Learn about the diverse range of applications for 2, 6-dimethyl pyridine.
