Scientific conference where the work was recently presented: XXIII Nutrition and Food Congress (Lisbon, Portugal)

Date on which the work was previously presented at the scientific conference listed: May 17, 2024

Objectives: To analyze the presence of alkylglycerols, vitamin K2 and tryptophan in ostrich oil.

Methods: Ostrich oil was purchased from an industry that manufactures the product for sale as a food supplement, located in Mirante da Serra, in the northern region of Brazil. The samples were sent for analysis to the chemistry department of the Federal University of Paraná and to the CEIMIC Life Sciences Testing Group in Pedreira/São Paulo, where they were analyzed using gas chromatography, a method used to identify and quantify unknown chemical compounds, precisely analyzing substances with different concentrations, from micrograms to picograms.

Results: The chromatograms generated on a mass-mass spectrometer in SIM mode (Selected Ion Monitoring) showed the presence of alkylglycerols in ostrich oil corresponding to 56.35mg/100mL and vitamin K2 being 1,399.88μg/100mL and tryptophan 230μg/100mL.

Conclusions: The importance of alkylglycerol supplementation for the immune
system and vitamin K2 and tryptophan for the body's homeostasis is well known.
The analysis of the results showed the presence of these nutrients in ostrich
oil, which can be considered a food source of alkylglycerols, vitamin K2 and
tryptophan. It could play a promising role in the immune system as it contains
these substances, but more studies are needed to prove their role in the body.
