The Microalga Phaeodactylum Tricornutum a Potential Fish Substitute?- Pharmacokinetic Study (MikroFisch)

June 4, 2024 updated by: University of Hohenheim

Die Mikroalge Phaeodactylum Tricornutum Ein Potentieller Fischersatz?- Pharmakokinetische Studie

In a cross-over design, pestos enriched with different levels of the microalgae Phaeodactylumtricornutum (2-3-4%) will be tested. The bioavailability of long-chain omega-3 fatty acids, in particular EPA and carotenoids, will be analysed in blood plasma postprandially within two days after a single dose. Pharmacokinetic parameters will be calculated from the measured data. The aim of the study is to gain insight into the bioavailability of selected microalgae constituents and the acceptance of microalgae pesto.

Detailed Description

The main objective of the project "Healthy nutrition through microalgae as a fish substitute" with the acronym MikroFisch, is to develop a novel fish substitute product based on microalgae biomass that provides us with essential nutrients. More and more people are interested in a healthy, sustainable diet and are looking for plant-based alternatives. These are available in a wide variety for meat, but not for fish, although sources of essential nutrients such as eicosapentaenoic acid and docosahexaenoic acid are urgently needed, which is where our concept of evaluating microalgae as a future food comes in. Based on current trends, the investigators see great development potential for our approach. The prerequisites for this are proof of the non-toxicity of the microalgae used, sufficient absorption of the nutrients they contain in the human gut, and the development of a presentation form that is suitable for food technology and sensory analysis. If these requirements can be met, a food product based on microalgae could enjoy a high level of acceptance. The Institute of Nutritional Medicine at the University of Hohenheim has been researching the microalgae PT for several years. As PT is not authorised as a novel food, studies on the suitability of the microalgae as a foodstuff must be carried out. The aim of the study is to characterise the pharmacokinetics of the dried microalgae Phaeodactylum tricornutum processed in a pesto ("investigational product") in healthy volunteers/patients in order to gain insights into its absorption, distribution in the organism, metabolisation and excretion. In particular, the time courses of the plasma concentrations of eicosapentaenoic acid (EPA) and the carotenoids fucoxanthin and b-carotene will be analysed, and the microalgae must also be properly processed into a tasty product before it can be used as food. For this reason, the concentration-dependent acceptance of the dosage form of the microalgae is also being analysed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Experimental: Pesto with 3% Phaeodactylum
Dried Microalgae integrated in the Pesto
Dietary supplement: Dried Microalgae biomass
The products to be tested are pestos enriched with different amounts of the microalgae Phaeodactylum tricornutum (3, 4 and 5%). After drying, the microalgae Phaeodactylum, which has already been used in two previous applications (application german ethic F-2020-001), is added to the pesto. Three different pestos will be produced and enriched with different amounts of the microalgae Phaeodactylum.
