“Manufacturers would come to us and say, 'We would really like to use more whey, but it keeps drying out our bars. What can we do?'” says Starla Paulsen, applications research manager for Glanbia Nutritionals Inc. (Monroe, Wis.).
In response to this request, Glanbia developed Barflex™, a partially hydrolyzed premium whey protein isolate designed to control water migration in nutrition bars; it is a solution to the extended shelflife challenge. Barflex is a unique whey ingredient with a functionality developed to reduce the drying and hardening that occurs in nutrition bars when standard whey proteins are used.
