Fifteen years ago, at least one multimated female yellow-legged Asian hornet (Vespa velutina Lepeletier 1836) arrived in France, which gave rise to a pan-European invasion.In this study, the isolation and characterization of chitin (CHI) that was obtained from Vespa velutina (CHIVV) is described.In addition, an easy procedure is carried M Accesories out to capture the raw insect, selectively and with high rates of success.

The chitin contents of dry VV was observed to be 11.7%.Fourier transform infrared spectroscopy (FTIR), solid-state NMR (ssNMR), elemental analysis (EA), scanning electron microscopy (SEM), and thermogravimetric analysis (TG) characterized the physicochemical properties of CHIVV.

The obtained CHIVV is close to pure (43.47% C, 6.94% H, and 6.

85% N), and full acetylated with a value of 95.44%.Additionally, lifetime and kinetic parameters such as activation E and the frequency factor A using model-free and model-fitting methods, were determined.

For CHIVV the solid state mechanism that follows the thermodegradation is of type F2 (random nucleation around two nuclei).The invasive Asian hornet is a promising alternative source of CHI, based on certain factors, Smart Switch such as the current and probable continued abundance of the quantity and quality of the product obtained.
