Protein microcapsules for hydrophobic ingredient encapsulation

Overview

The development of protein microcapsules using elastin-like polypeptides (ELPs) presents a groundbreaking approach for encapsulating hydrophobic ingredients. These biodegradable microcapsules are formed through a water-based process that leverages the amphiphilic nature of recombinant proteins. This technology is particularly valuable for industries such as pharmaceuticals and cosmetics, where the encapsulation of active hydrophobic ingredients is crucial. By utilizing a temperature-controlled phase transition, the microcapsules provide a versatile and environmentally friendly solution for ingredient delivery.

Technical specifications

The core of this technology is the use of ELPs, which are penta-repeat polypeptides derived from tropoelastin. These polypeptides undergo an inverse phase transition from soluble to insoluble states under specific temperature conditions, forming microcapsules with hydrophobic inner walls. The microcapsules range from 1 to 5 μm in size and can encapsulate various hydrophobic molecules, including small molecules, proteins, and microparticles. The process involves mixing hydrophobic cargo with amphiphilic proteins and inducing microcapsule formation through temperature control. This method allows for efficient encapsulation in a biodegradable and non-hazardous manner.

Technology readiness level

Currently at Technology Readiness Level 5, this technology has been validated in a laboratory setting with successful formation and encapsulation of hydrophobic ingredients. Future validation efforts will focus on optimizing protein sequences, production through recombinant DNA technology, and scaling up the processing conditions to enhance capsule stability and encapsulation efficiency. Partnerships for further development and funding are sought to advance this promising encapsulation solution.
