Whey protein concentrates and isolates

At Glanbia Ingredients Ireland (GII), we’re at the forefront of whey protein processing and technologies. We’ve been processing whey protein at our Ballyragget plant for four decades, and in 2012 invested a further €21m in whey protein operations at the site. In the process, we’ve developed a wide range of top-quality, highly specialised whey protein concentrate (WPC) and whey protein isolate (WPI) variants.

Benefits and applications

To produce our WPC powders, we spray-dry ultrafiltered whey with protein levels ranging from 28% to 35%. Our WPI powders have a minimum protein level of 88%, thanks to a process of microfiltration. Our whey proteins are also available in heat-stable variants. Our WPI is derived from our pasture-fed cows using state-of-the-art technology, which produces a clean, natural flavour.

We supply these value-adding and sustainable whey protein ingredients globally, tailored to customers’ needs, across a range of application areas, including:

  • Sports nutrition
  • Infant formula
  • Nutritional foods and supplements
  • Ice cream
  • Yoghurt and desserts
  • Cheese
