Ozone microbubble pre-treatment for browning-free plant protein HME
Innovative ozone microbubble conditioning reduces browning in plant-based protein HME processing, enhancing color, texture, and flavor without additives or equipment changes.
Overview
The ozone microbubble conditioning (OMC) technology offers a groundbreaking solution for the plant protein industry, addressing the common issue of browning during high moisture extrusion (HME) processing. This innovative pre-treatment employs ozonated water delivered as microbubbles to oxidize chromogenic compounds and Maillard browning precursors upstream of the HME process. The result is a significant reduction in dark-brown coloration, improved product texture and flavor, without the need for synthetic additives or costly equipment modifications.
Technical specifications
Key features:
- Ozone microbubble delivery: Uses microbubbles (≤50 μm) to effectively oxidize browning precursors within the protein slurry.
- Enhanced product quality: Increases lightness (L* +22.5), chewiness (+29%), and water holding capacity (+29%) while reducing beany off-flavor by 79% compared to untreated controls.
- Compatibility: Integrates seamlessly with existing HME lines without requiring modifications.
- Scalable process: Defined process window with characterized failure modes supports reliable scale-up.
Technology readiness level
The OMC technology is currently at Technology Readiness Level 4. It has been validated in laboratory settings and is progressing towards broader substrate applications and pilot-scale validations. Future phases will include trials for different protein sources and analog formats, regulatory assessments, and cost modeling, with ongoing technical support for scale-up and GMP implementation.
