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.

Purpose? http://my-chem-assignment.blogspot.com

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.

Pros Cons Cost Effective Longer Shelf life Enriches food Foods become safer to eat Allergic reactions Harmfully affect children Cancer
