Results
Protein digestibility & PDCAAS
The NUTRALYS® range of pea proteins is a great source of highly digestible proteins with almost full amino acid profile opening the opportunity to good synergies with cereal-based proteins. For example, when using the 2007 amino acid requirements, a ration of 85% NUTRALYS® pea protein/15% wheat gluten allows to reach an amino acid score over 100. |
Kinetic of digestion
NUTRALYS® S85 Plus & Whey:
“Fast protein” |
![]() |
NUTRALYS® pea protein: Increase in viscosity during the gastric acidification and sudden drop in viscosity after addition of the gastric enzymes, suggesting the aggregation into particles “Intermediate-fast protein” |
![]() |
Casein: High and sustained increase in viscosity, suggesting the formation of an enduring protein network
“Slow Protein” |
![]() |
![]() |
The fast or intermediate-fat proteins could facilitate rapid amino acid delivery to the bloodstream and may be of potential interest for muscle protein synthesis during the recovery phase. |
Conclusion
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
