Native Whey Protein Isolate (nWPI-Pro)
Pure Native Whey Protein from Fresh Australian Milk
ProviCo’s Native Whey Protein Isolate (nWPI-Pro) is produced directly from fresh skim milk rather than cheese whey, preserving the natural functionality and nutritional quality of native whey proteins. Using gentle membrane filtration, concentration and low-temperature spray drying, the process produces a highly purified whey protein isolate with excellent solubility, a clean neutral dairy flavour and minimal heat denaturation.
Unlike conventional cheese whey protein isolate, nWPI-Pro contains virtually no glycomacropeptide (GMP), resulting in a protein profile that more closely resembles the natural whey proteins found in milk. The product is naturally rich in branched chain amino acids (BCAAs), particularly leucine, making it ideal for applications requiring rapid muscle protein synthesis, high nutritional quality and excellent sensory performance. Leucine concentration is at approximately 130 g/kg together with high levels of lysine, valine and isoleucine.
Manufacturing Process
ProviCo nWPI-Pro is manufactured from fresh Australian skim milk using a gentle process designed to preserve native protein functionality:
- Fresh skim milk collection
- Pasteurisation
- Low temperature membrane filtration to separate native whey proteins from casein
- Ultrafiltration and diafiltration to concentrate and purify proteins
- Gentle spray drying
This process minimises protein denaturation while maintaining excellent nutritional and functional properties.
