Ultraviolet systems for enhancing wheat flour safety
Innovative UV light systems utilizing different wavelengths to improve wheat flour safety without compromising quality. This method effectively reduces bacterial contaminants, ensuring food safety and maintaining flour quality.
Overview
The proposed ultraviolet (UV) light systems are designed to enhance the safety of wheat flour by effectively reducing bacterial contaminants while maintaining the flour's quality. By employing different UV wavelengths, specifically 254 nm and 222 nm, these systems provide a non-thermal method to inactivate bacteria, ensuring food safety without altering the flour's essential properties such as color, gluten content, and water-retention capacity.
Technical specifications
Key features:
- Utilizes two UV wavelengths: 254 nm (conventional) and 222 nm (far-UVC)
- Effective in inactivating bacteria on wheat flour at varying doses
- Maintains flour quality, including color, gluten content, and moisture levels
- Non-thermal process that minimizes changes in flour composition
Research and validation:
- Conducted in a biosafety level 2 laboratory
- Involves bacterial inoculation and enumeration to determine optimal UV dose and wavelength
- Statistical analysis ensures reliable results and feedback integration from stakeholders
Technology readiness level
The current technology readiness level is 4. The system has been validated in laboratory environments, demonstrating its efficacy in bacterial inactivation on wheat flour. Further validation is planned to optimize UV parameters and assess the impact on flour quality.
