|A method for scalable, non-thermal or low temperature pasteurization of powdered or particulate food.|
Microbial contamination of grains, powdered food ingredients and read-to-eat food products can result in serious illness upon consumption. Therefore, food manufacturers are required to implement pasteurization procedures to decontaminate their products before packaging. In addition, recalls of food are expensive and can damage manufacturers’ reputations. Using traditional thermal methods such as hot air or steam can change the quality of food, and are not suitable for pasteurization of flour or other powdered or particulated foods. In addition, poor heat transfer properties render this process inefficient. Non-thermal treatment methods such as X-rays and UV light, on the other hand, can cause significant chemical and physical damage to the food. Therefore, an efficient and effective food pasteurization method with minimum quality changes is needed.

Phase of DevelopmentWorking continuous system prototype. Tested several foods and characterized efficiency with respect to system parameters.
Key Benefits & Differentiators
- Highly effective pasteurization: microbial count reduction by over 3-5 logs. Better than conventional hot air/steam technique.
- Low cost equipment. Energy efficient process reduces capital and operational costs compared to UV technology.
- Maintain food quality by not heating food beyond 60°C with no chemical or physical damage to food. Fully non-thermal processing for some applications.
- Quick processingsupports high throughput rate.
- Easy implementation in processing units; works well with food on conveyor.
- Can be integrated easily in most flour mills and powdered food processing facilities, with no added operator supervision.
- Pasteurization of grains (wheat, corn, etc.), and spices
- Pasteurization of powdered foods (NFDM, flour, ground black pepper, etc.)
- Disinfecting cosmetic and pharmaceutical products
- Disinfecting liquid and solid form consumer materials
