Pectin-based microencapsulation for hydrophobic materials

Overview

This solution leverages pectin, a natural and biodegradable substance, to form a hydrogel shell around hydrophobic core materials. The encapsulation process aims to protect the core material while enabling controlled release through mechanisms such as pH changes, dehydration, shear, or microbial activity. Using pectin supports stability in low pH environments and can enhance plant immunity, supporting applications where encapsulation and protection are important.

Technical specifications

Key features:

• Utilizes pectin, a natural hydrocolloid, to form a stable hydrogel shell
• Provides multiple release mechanisms: pH, dehydration, nozzle shear, and microbial activity
• Suitable for diverse applications requiring encapsulation of hydrophobic materials
• Expertise in selecting starting materials and processing technologies to achieve desired functionality

The process involves dispersing the hydrophobic material in a pectin solution, followed by spray drying to form microspheres with a pectin gel outer layer. The integrity of the encapsulated materials is evaluated using advanced microscopy and spectroscopy techniques.

Technology readiness level

This solution is currently at Technology Readiness Level 3. The concept has been validated at a lab scale, and further development and validation are planned to refine the process and support commercial viability.
