According to Food Security Information Network’s report, by 2023, over 2.5 billion people were facing severe hunger. Due to rapid changes in social environments such as climate change, and conflicts, insects have been accepted as a food source in many countries. However, before insects can be recognized as a suitable long-term nutrition supply, the composition and concentration of their amino acids need to be confirmed.
A quantitative analysis was conducted on the powdered form of edible insects (Acheta domesticus) using the LCMS-8060NX triple quadrupole mass spectrometer, analyzing a total of 39 compounds, including 9 essential amino acids, 11 non-essential amino acids, and 19 other amino acids and related peptides. 2-Aminobutyric acid (AABA), which was found to be the most abundant among the amino acids, has been reported to possess antioxidant properties and efficiently increase the levels of intracellular glutathione when consumed orally. Glutamine and glycine were the next most prominent amino acids, collectively accounting for 90% of the total content. Furthermore, the results of this study demonstrate that insect food contains a variety of D-amino acids, which are typically produced by intestinal bacteria in the human body and can regulate the survival and differentiation of host B cells.
