Plant-derived nanocapsules for encapsulating hydrophobic molecules

Overview

The plant-derived nanocapsules developed through nanoprecipitation present an innovative solution for encapsulating hydrophobic molecules in oil substrates. Leveraging the natural and cost-effective materials such as zein and ferulic acid, these nanocapsules offer an eco-friendly and efficient method for delivering active ingredients like curcumin. The potential applications are vast, including pharmaceuticals, nutraceuticals, and cosmetics, where precise control over particle size and release properties is critical.

Technical specifications

Key features:

• Utilizes nanoprecipitation, a technique allowing precise control over nanocapsule size (100–1000 nm) and properties.
• Composed of natural substances: zein (a corn protein) and ferulic acid, ensuring biocompatibility and sustainability.
• Capable of encapsulating active hydrophobic ingredients, such as curcumin, within an oil medium (e.g., palm or soybean oil).
• Flexible formulation through adjustable proportions of proteins, small molecules, and oils to meet specific requirements.

Technical process:

• Dissolution of the active ingredient in an edible oil to form Component A.
• Zein and ferulic acid, dissolved in a water-miscible organic solvent with a cross-linker, form Component B.
• Mixing of Components A and B followed by rapid water addition to induce nanocapsule formation via violent vortex oscillation.
• Characterization of nanocapsules using techniques such as DLS, GC-MS, CLSM, and TEM.

Technology readiness level

The technology stands at TRL 4, indicating that the basic technological components have been integrated to validate the nanocapsule formation in a laboratory setting. Further development and validation will involve optimizing the process conditions and exploring additional active ingredients for broader commercial applications.
