Hybrid diffusion-buffering model for pH prediction in food matrices
A predictive model for brine acidification in high-moisture RTE foods, integrating organic-acid chemistry and matrix buffering to optimize pH levels and quality. Designed to enhance food safety by achieving pH ≤4.5, it minimizes trial-and-error and supports regulatory compliance.
Overview
The hybrid diffusion-buffering model is an innovative predictive tool designed to optimize the brine acidification process in high-moisture ready-to-eat (RTE) foods. It integrates organic-acid chemistry with matrix buffering and diffusion mechanics to accurately predict pH levels over time at both surface and core of food inclusions. This ensures the food reaches the safety target of pH ≤4.5 while maintaining its organoleptic and nutritional quality. By reducing trial-and-error in process development, the model aids in scaling up production and supports compliance with food safety regulations.
Technical specifications
- Predictive modeling: Combines lactic, acetic, and citric acid chemistry with diffusion and buffering dynamics to predict pH changes.
- Comprehensive parameters: Accounts for inclusion size, matrix properties, temperature, and organic-acid selection.
- Calculator tool: Recommends operating conditions such as acid strength, brine-to-product ratio, mixing and hold time, and temperature to achieve target pH.
- Regulatory support: Provides traceable assumptions, verification sampling guidance, and uncertainty bounds to assist in regulatory readiness and HACCP programs.
Technology readiness level
This technology is currently at TRL 2, indicating that it is in the early stages of development, with planned validation phases to enhance and finalize the model for commercialization.
