Natural-based disinfectants for controlling lactic acid bacteria in food products
This research focuses on developing natural-based disinfectants using plant molecules and bioactive extracts to control lactic acid bacteria in food products. The aim is to enhance food safety and shelf-life while aligning with consumer preferences for natural ingredients.
Overview
This innovative solution involves the development of natural-based disinfectants designed to control lactic acid bacteria in food products. By utilizing plant molecules and bioactive extracts, which are approved for use in the food industry, this approach aims to improve microbiological safety and extend shelf life. The use of natural ingredients meets the growing consumer demand for simpler, more natural food additives.
Technical specifications
The core technology leverages the antimicrobial and antioxidant properties of plant-derived compounds. These extracts have been shown to facilitate a bacterial kill rate of at least 1-2 log-reduction, ensuring effective microbial control. Additionally, the integration of short-term UVC irradiation enhances microbial reduction on food surfaces without affecting product quality.
Key features:
- Utilizes bioactive plant extracts with proven antimicrobial properties
- Offers potential for 1-2 log-reduction in bacterial presence
- Includes optional UVC irradiation for enhanced microbial control
Technology readiness level
The technology is currently at TRL 5, having undergone laboratory testing and validation. Future validation includes in vitro testing under industrial-relevant conditions to ensure compliance with food safety and shelf-life requirements.
