Ketones and Aldehydes as Flavoring Agents
By
Yemi Oduwole
What are Flavoring Agents?
Flavoring agents are considered the largest compounds used as FOOD ADDITIVES. Food and beverage applications of these additives are not limited to dairy, fruit, nut, seafood, spice blends, vegetables and wine.
Alcohols, esters, aldehydes, ketones, protein hydrolysates and MSG are examples of flavoring agents.

Aldehyde as a Flavoring Agent
OCTANOL
Other names are C8-Aldehyde, and Octyl-Aldehyde
Fatty alcohol found in essential oils
Colorless, but have a very strong odor
Flavoring agents made from this compound are used in foods such as baked goods, gelatins, and ice cream.
Also used in detergents, soaps, as well as creams and light fragrances.
Synthesis
Cinnamaldehyde
Isolated in 1834 by Dumas and Péligot
Extracted from cassia and cinnamon bark oils
Synthetic production preferred
Mostly used in bakery goods, chewing gum, toothpaste, mouthwash and candy.
Ketone as a Flavoring Agent
Raspberry Ketone
Chemical from red raspberries (Rubus idaeus)
Olfactory stimulant
Exerts anti-obese actions
Alters lipid metabolism
Growth inhibition and antifeedant activity
A sought-after aroma that is widely used in the food industry for flavor of beverages and dairy products.

cautions
Even though the word “raspberry” may appeal to people, the supplement is actually NOT derived from raspberries
Insanely expensive extraction
A kilogram (2.2 pounds) of whole raspberries only contains 1-4 mg of raspberry ketones
Raspberry ketones you find in supplements are synthetically made via an industrial process and are not natural
Not a single study on raspberry ketones in humans.
