A range of high nutritional quality pea proteins with characteristic digestion profiles.

Objectives of the study 

Roquette has developed a range of vegetable proteins produced from yellow pea. NUTRALYS® pea protein and the new grade NUTRALYS® S85 Plus are great sources of proteins (85%) both qualitatively and quantitatively, rich in Branched Chain Amino Acids and Arginine delivering different technical features.

The objectives of the present research were to investigate:

  • their nutritional quality through the protein digestibility and the protein digestibility-corrected amino acid score (PDCAAS),
  • their kinetic of digestion under simulated in-vitro gastric conditions.


The 2 pea proteins isolates evaluated in these studies displayed a high nutritional quality profile. NUTRALYS® pea protein is an “intermediate-fast protein” and NUTRALYS® S85 Plus is a“fast-digested protein” making these ingredients adapted to specific nutritional needs. These results show that plant-based proteins, like those of the NUTRALYS® range, may allow designing high quality protein rich foods and beverages
