Edible, plant-based biopolymer carriers for sensitive ingredients
Cellulose microspheres offer a bio-based encapsulation solution for stabilizing sensitive ingredients in low-pH transparent beverages, enhancing stability and sensory profile while maintaining clarity.
Overview
Naturbeads has developed innovative cellulose microspheres designed to stabilize and protect sensitive active ingredients in low-pH transparent beverages. These biopolymer carriers offer a bio-based, biodegradable, and scalable solution, ideal for clean-label formulations. They have been successfully tested to enhance the activity, stability, and processability of small molecules such as enzymes, antigens, and colorants by creating a protective microenvironment that reduces degradation pathways like oxidation, discoloration, and acid-induced loss of activity.
Technical specifications
- Protective Functionality: The microspheres adsorb or associate with active ingredients, offering a controlled microenvironment that minimizes degradation.
- Compatibility: Designed for transparent, low-pH beverage systems, preserving clarity and sensory profile.
- Bio-based and Biodegradable: Made from cellulose, these carriers support clean-label formulations.
- Scalable Solution: Engineered for large-scale production with controlled morphology and optical properties to minimize turbidity.
Technology readiness level
Currently, the technology is at TRL 4, having been validated at the laboratory scale. Future validation efforts will focus on optimizing particle size, surface properties, and loading methods, followed by pilot production and application-specific validation under various shelf-life conditions.
About Naturbeads
Naturbeads is a sustainable materials startup that specializes in producing biodegradable cellulose-based microspheres to replace harmful microplastics. The company utilizes a patented, continuous, and closed-loop manufacturing process that transforms cellulose—derived from natural sources like trees—into perfectly spherical, uniform particles. By using a unique green-solvent system and membrane emulsification, Naturbeads can precisely control particle characteristics such as size, porosity, and surface texture without altering the chemical structure of the cellulose. This innovative technology allows for the creation of high-performance beads that maintain the functionality and cost-effectiveness of traditional plastic particles while ensuring full biodegradability.
The company's solutions serve a diverse range of industries, including cosmetics, life sciences, paints, coatings, and various industrial applications where microplastics are traditionally used as sensory enhancers, thickeners, carriers, or separators. By providing a sustainable, 100% bio-based alternative, Naturbeads helps partners meet evolving environmental regulations and reduce their ecological footprint. Having transitioned from its origins at the University of Bath to scaling up industrial production, the company has successfully established its first commercial manufacturing plant in Italy to meet growing global demand for eco-friendly, circular-economy materials.
