Danisco and DuPont Qualicon strengthen natural food safety

Danisco and DuPont Qualicon have joined forces in the US to enhance natural food safety and shelf life extension.

Drawing on patented protective cultures from Danisco and an award-winning detection system from DuPont Qualicon, the companies are exploring a potential tool for the early and accurate prediction of shelf life in naturally protected dairy products.

The principles for shelf life prediction were confirmed by an extensive joint study guided by Robert F. Roberts of Penn State University.

Using nearly 500 samples, the study found that Danisco’s Holdbac YM protective cultures gave fresh fermented dairy products significantly longer protection against yeast and mould than other solutions, even under challenging conditions.

The DuPont Qualicon Bax System polymerase chain reaction (PCR) assay for screening yeast and mould was seen to detect mould up to 14 days earlier than other standard methods.

The use of both solutions makes it possible to prolong product life while maintaining an all-natural positioning.
