Achtergrond van het onderzoek
The primary objective of this cross-over study is to assess the post-prandial serum amino-acid profile of duckweed protein in 15 healthy adult volunteers in comparison to a another plant-based high-protein crop: green pea. A secondary objective is to assess post-prandial plasma glucose and insulin responses after a single intake of duckweed protein in healthy adult volunteers in comparison with the reference pea protein, as well as the acute health parameters heart rate, blood pressure and aural temperature and the occurrence of gastro-intestinal complaints.
Doel van het onderzoek
• The amino acid profile of duckweed derived protein may be different from pea derived protein.
• The glucose and insulin responses of duckweed protein may be different compared to those of pea protein.
• A single intake of duckweed and pea protein will give no negative effects in acute health parameters.
• The number of gastro-intestinal complaints after a single intake of duckweed may be different compared to the number of gastro-intestinal complaints after a single intake of pea protein.
Onderzoeksopzet
Eleven blood samples are taken each 15-30 minutes for a period of 3 hours.
Gastro-intestinal complaints during 4 days.
Onderzoeksproduct en/of interventie
Subjects come to the research facility in fasting state twice to consume a soup with duckweed or a soup with pea. Two blood samples will be drawn before consumption. After consumption, blood samples will be taken 9 times (each 15-30 minutes) for a period of three hours to assess the free amino acids as well as glucose and insulin levels to get insight into the post-prandial metabolism of the two plant proteins.
