The growing number of shelf-stable foods makes it convenient for people to eat while on the go. It is now possible to obtain dairy products without entering the refigerated aisle. Fermented milk products contain probiotics that have digestive health benefits. Therefore, the Seeker is looking to preserve bacterial viability in ambient products for extended periods.

This Theoretical Challenge requires only a written proposal.


Lactic acid bacteria are the organisms used to produce fermentated milk products. Studies have shown that these bacteria are also beneficial for promoting gut function and health. Aseptic production of shelf-stable foods requires high temperatures, thus killing the resident bacteria. Reintroduction of active cultures has resulted in accelerated spoilage through excessive acidification, proteolysis, loss of sweetness, and physical changes to the product. Therefore, the Seeker is searching for novel methods that maintain bacterial viability in fermented dairy products stored at ambient conditions, whilst avoiding spoilage.

This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker.

To receive an award, the Solvers will have to transfer their exclusive intellectual property (IP) rights to the Seeker.

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on December 1, 2018. 

Late submissions will not be considered.

What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is a Theoretical IP Transfer Challenge?

An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service.

This Challenge is a Theoretical-IP Transfer Challenge, meaning that Solvers must relinquish all rights to the Intellectual Property (IP) for which they are awarded. By contrast, Theoretical-Licensing means that the Seeker is requesting non-exclusive rights to use the winning solution. For these forms of a Theoretical Challenge, Solvers that do not win retain the rights to their solution after the evaluation period is complete. The Seeker retains no rights to any IP not awarded.
