Study Objectives

Methods

Protein digestibility

  Growing rats
n=10/group     
   Control period followed by 5-day balance period
   Diet providing 10% of proteins or no protein
   Endpoints: Nitrogen intake & Fecal nitrogen

 

PDCAAS evaluation

 

Kinetic of digestion

  • “NIZO SIMPHYD model”
  • Static model simulating the gastric digestion combined with in-line viscosity measurements

 

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:
no evolution of viscosity

 

 

“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
