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.

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.
