Collagens for bars

All Rousselot collagen solutions will help you create bars with enhanced texture, taste, mouthfeel, and improved shelf stability.

Combine whey and collagen to enhance texture and stability

ProTake hydrolyzed collagen boosts protein content in bars to over 30% - 50% while maintaining a soft texture. When combined with other protein sources such as Whey or Milk Protein Isolate (WPI, MPI), ProTake improves processability, reducing cracks and hardness. This combination delivers high protein levels with an exceptional texture, bite, and overall sensory experience
