Combined non-thermal treatments and mathematical modeling for extended shelf life
Innovative approach utilizing natural additives, cold plasma, and pulsed light to extend perishable food shelf life. Mathematical modeling optimizes storage conditions, enhancing preservation without compromising quality.
Overview
The proposed solution leverages a combination of non-thermal treatments and advanced mathematical modeling to extend the shelf life of perishable foods. By integrating natural additives such as organic acids, along with cold plasma and pulsed light, a complementary preservation barrier is created. This approach not only inhibits microbial growth but also reduces the degradation of active compounds, ensuring food safety and quality are maintained over an extended period. The mathematical models developed will optimize storage conditions based on the composition and characteristics of each food product.
Technical specifications
Key features include:
- Use of non-thermal techniques such as cold plasma, pulsed light, and organic acids for microbial inactivation.
- Tailored preservation strategies based on food composition, pH, water activity, and target microorganisms.
- Advanced mathematical modeling, including deterministic, probabilistic, and AI-based models, to optimize formulation and storage conditions.
- Collaboration with experts in food safety and processing to ensure comprehensive analysis and application.
Technology readiness level
This innovative approach has reached Technology Readiness Level 9, indicating that it has been thoroughly validated and is ready for commercial application in the food industry. Extensive testing and data analysis have confirmed its effectiveness in extending food shelf life without compromising safety or quality.
