Biodegradable amylose inclusion complexes for encapsulating hydrophobic compounds
Innovative biodegradable amylose inclusion complexes (AICs) using high amylose corn starch to encapsulate hydrophobic compounds, such as fatty acids, for various applications. These AICs demonstrate antimicrobial properties and can be resuspended in water.
Overview
Biodegradable amylose inclusion complexes (AICs) offer an advanced solution for encapsulating hydrophobic compounds, including fatty acids and their derivatives. Utilizing high amylose corn starch and jet cooking, these complexes form stable, water-resuspendable powders. Their bioactive properties, such as antimicrobial and antifungal capabilities, make them suitable for a range of applications in industries requiring bioactive, biodegradable materials.
