Ketones and Aldehydes
as Flavoring Agents
By

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.
Biosynthesis
Differences?
“Miracle Fat Burner”
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.
