Beverage giant seeks natural solution to yeast and mold spoilage in acidic beverages
A leading food and beverage manufacturer is looking for new natural ingredients that can prevent yeast and mold spoilage in acidic shelf-stable beverages.

In a posting​ on the website NineSights, open innovation expert NineSigma says it is “representing a Fortune 500 Packaged Foods Company​” that produces many products that require a hot fill to reduce cross contamination and sterilize the container.

Lower temperature-filling, lighter PET bottles

The client wants to reduce the filling temperature of high acid beverages from 175-185°F to less than 150°F so that cheaper, lighter weight PET bottles can be used, or cost savings can be realized by eliminating the heat set step for PET bottle production, explains NineSigma.

“New, natural additives that can preserve sterility and prevent cross contamination at filling could enable a lower temperature fill process, allowing for lighter weight bottles and/or elimination of heat set for PET bottles.

“Both changes would result in lower cost materials.”

Solutions must be natural, safe, with minimum taste impact

Solutions must be natural and safe; prevent mold/yeast over a 12-month shelf-life, enable filling temperature below 150°F in an open-fill system and have a neutral/minimal taste impact.

Crucially, they must not introduce significant additional capital equipment investment, while the cost savings achieved through using lower temperatures and lighter bottles must be greater than the incremental food additive cost.

“[Our] client is not interested in process alterations that require significant changes in infrastructure ​… [such as] systems that create a nitrogen headspace”, ​adds NineSigma, which is asking interested parties to respond by November 30.

Thanks for highlighting one of my most recent projects. Packaging cost is an important focus area for many companies. This is just one example of an approach of interest. Many more projects like this can be viewed at our website -
