A technology for processing bee corpses and obtaining chitin-melanin and melanoprotein complexes has been developed. The obtained complexes of biopolymers were studied by the methods of absorption spectroscopy, electron paramagnetic resonance (EPR) spectroscopy, thermogravimetry, and differential scanning calorimetry. The elemental composition of preparations was characterized. It was shown that the properties of the melanin-containing products of the processing of bee corpses are typical of chitin and melanin of animal origin. The results of EPR spectroscopy and thermal analysis are indicative of the diversity and structural complexity of the obtained products.
