Hilmar supplies companies worldwide with whey protein made from sweet whey. The source of our whey comes from our large-scale cheese manufacturing operations that provide the freshest, highest quality whey stream. We further process the liquid whey, removing much of the water, carbohydrate and minerals through filtration with further processing for fractionation, agglomeration and hydrolysis to produce our wide range of functional and nutritious ingredients.

We partner with our customers — from the most prominent retail brands to start-ups — to refine existing products, create new applications and build great consumer brands.
