Encapsulation of food ingredients

Area of Science:

• Food Science and Technology
• Materials Science

Background:

• Microencapsulation is an emerging technology for food ingredient protection, stabilization, and controlled release.
• Commonly used wall materials include starches, proteins, gums, and lipids.

Purpose of the Study:

• To review microencapsulation techniques for food ingredients.
• To discuss the selection of coating materials.
• To present methods for characterization and controlled release.

Main Methods:

• Review of existing literature on microencapsulation techniques.
• Analysis of various encapsulating (wall) materials.
• Discussion of characterization methods and controlled release mechanisms.

Main Results:

• Identified key microencapsulation methods: spray-drying, freeze-drying, fluidized bed-coating, extrusion, cocrystallization, molecular inclusion, and coacervation.
• Detailed the properties and applications of different wall materials.
• Presented characterization techniques and controlled release principles.

Conclusions:

• Microencapsulation offers significant benefits for food ingredient delivery.
• Careful selection of wall materials and techniques is crucial for desired functionality.
• Further research can optimize microencapsulation for novel food applications.
