    The submission process for new proposals is closed. Proposals submitted before the deadline will follow the standard evaluation process.

Desired outcome

We are seeking efficient and effective technologies to sterilize powdered seasonings without impacting performance characteristics.

The powdered seasonings provided to PepsiCo are often comprised of onion or garlic powder. The complete seasoning, or its component ingredients, have the potential for the presence of undesirable microbial contamination.

Treatment of these powders by way of irradiation can be effective, however, this technique is not permitted without proper labeling in certain global regions. Given the large surface area of the powders in question, other methods of microbial eradication have typically been ineffective.

We would like to identify potential technologies to remove microbial contamination without negatively impacting the physical attributes or flavor profile of the seasoning.


Details of the Innovation Need


  • Significant reduction in both the microbial loading of the seasoning and of the pathogens of concern
  • No adverse effects on the seasoning/flavor profile of the seasoning
  • No adverse effects on the quality parameters of the seasoning (e.g. flowability)
  • No effect on H&S
  • Low cost


  • Be applicable to other powders/flavors
  • Minimum cost to operate
  • Be applicable across a range of different seasoning application formats

Possible solution areas

  • With the exceptions noted below, we are interested in all approaches that can meet the Key Success Criteria

Discarted solutions

  • Unless significant advancement has been achieved, we are already familiar with the following technologies: Ethylene oxide and Irradiation
