CFC Flavor Application & Processing Technology

Question 1

The primary purpose of microencapsulation in flavor technology is to:

Accepted Answer

Protect volatile compounds and enable controlled release

Answer

Microencapsulation shields sensitive flavor compounds from heat, oxygen, and moisture during storage and processing, then releases them at the desired time or condition.

Question 2

Spray drying for flavor encapsulation most commonly uses which carrier material?

Accepted Answer

Modified starch or maltodextrin

Answer

Modified starch and maltodextrin are the most widely used wall materials in spray-dried flavor encapsulation due to their film-forming properties, low cost, and food-grade status.

Question 3

Coacervation as a flavor encapsulation method involves:

Accepted Answer

Phase separation of a polymer coating that deposits around the flavor core

Answer

In coacervation, a change in conditions (pH, temperature, or addition of a second polymer) causes a polymer-rich phase to separate and coat the dispersed flavor droplets.

Question 4

Which property is most critical when selecting a wall material for flavor encapsulation?

Accepted Answer

Compatibility with the core and oxygen barrier performance

Answer

The wall material must be chemically compatible with the flavor core and provide adequate barrier properties against oxygen and moisture to prevent oxidation and loss of volatiles.

Question 5

Emulsified flavor systems require an emulsifier because:

Accepted Answer

Flavor compounds are typically lipophilic and must be stably dispersed in aqueous food systems

Answer

Most flavor compounds are hydrophobic; emulsifiers reduce interfacial tension between oil and water phases, allowing uniform flavor distribution in aqueous food matrices.
