FTIR spectra to analyse the chemical composition of PDEVs. Characteristic bands of lipids, proteins and carbohydrates are highlighted in the plots. (A) highlight the hydroxyl and amine groups between 3200–3400 cm⁻¹, (B) indicate lipid-associated C-H stretching between 2800–2950 cm⁻¹, (C) and (D) indicate the protein region at 1600–1500 cm⁻¹ and (E) 1000–1200 cm⁻¹ highlights the C-N stretches of the compound.
