How are flavors made?
4 methods of flavor formation:
1. enzymatic reactions2. non-enzymatic reactions3. fermentative reactions4. autoxidative reactions
Kristin
What are artificial flavorings?
Artificial flavorings are chemical compounds added to food products to mimic the taste of a natural flavor.
Kristin
Flavor Analysis
- new compounds are identified for their chemical structure or important odor note- analysts must choose the right procedure/conditions to isolate the chemical structure without destroying it
Examples of analysis techniques: gas liquid chromatography (GLC), mass spectrometry (MS), high performance liquid chromatography (HPLC)
Kristin
Flavor Manufacturing
3 principle methods to obtain flavor materials
1. gain from natural sources by ways of physical methods (extraction, steam distillation)2. produce it by chemical synthesis3. obtain material as a reaction flavor
Kristin
Flavor Manufacturing
conditions for producing a flavor compound: 1. chemical structure of flavor compound must be known2. purchasing cost of material must not exceed a certain limit3. legislation must be cleared4. consumer must accept and buy flavored end-product
Kristin
Synthetic Flavor Ingredients and the Future
- a better understanding of artificial flavoring behavior and interactions is crucial and essential for the future (knowledge of sensory properties, commercial availability, and toxicological behavior)
- precise descriptive language using common food flavor specific terms to describe flavor profiles is needed world-wide
- synthetically compounded flavors will continuously improve regarding quality, commercial, and ecological aspects

What’s wrong with Natural Flavor?
● Some derived from waste products
● Low intensity result in poor stability
● Extraction change flavor profile
● Natural enzyme result in off-flavors
● Labeling abuse

21st Century Natural Flavor
It became increasingly necessary to use desirable natural flavoring effects, but recreated from synthetic components of known character, purity, safety

Benefits of Artificial Flavor
Consumer’s Perspective
● Economically beneficial/ Cheap
● Very long shelf-life● Always available in the
market● Consistency guaranteed
Producer’s Perspective
● Withstand severe processing conditions
● Independent of natural cropping seasons
● Adjustable to optimum desired flavor
Alvina
Costs of Artificial Flavor
Producer’s Perspective
● Prone to “Chemical” abuse
● Higher toxicity level compare to Natural Flavor
Consumer’s Perspective
● Difficulty in labeling product
● Less range of flavor profile compare to Natural Flavor
● Solvent or carrier component controversy

Natural Flavors Artificial Flavors
-More accurate - Less accurate-Layers of flavors - No layer of flavor

The Effect of Artificial Flavors on Sensory System…
•Artificial flavors undergo same reactions as natural flavors do in the sensory system•Smell & taste components
Janice
What did scientific studies reveal?• MSG ( > 3000 mg) may not be safe to consume
• MSG has no long-term effects
• Injection of MSG can induce obesity, diabetes, retinal degeneration and neurotoxic effects in rodents (not ingestion)
