Whey protein isolates

Whey protein isolate is obtained by reducing the fat and carbohydrate content of whey. This process results in a protein content of at least 90 %. Thanks to this process, whey isolates have a lower lactose content than whey protein concentrates, making it an appealing choice for people who are lactose intolerant. Due to their composition, whey protein isolates are particularly fitting for nutritional applications, especially sports nutrition products.

At LACTALIS Ingredients, we aim to expand our nutritional ingredients offerings and as a whey protein manufacturer we provide a range of whey protein isolates designed to best meet the specificities of your products:

  • 90% protein minimum on dry basis
  • Regular or instant (soya or sunflower lecithin)
