摘要

Apis mellifera brood consumption represents a potential solution to meet the growing demand for high-quality protein in response to global population growth. This study evaluated the nutritional quality of proteins from worker and drone broods at different stages (larva, early pupa, and late pupa), determining their essential amino acids (EAA), digestibility, protein digestibility, corrected amino acid score (PDCAAS), the protein efficiency ratio (PER) and biological value (BV). Significant influence (p < 0.05) was found between castes and developmental stages on protein quality parameters. Early pupae drones had higher protein content (40%) and superior quality, with high levels of leucine (10.56 g/100 g), lysine (9.54 g/100 g), and valine (7.5 g/100 g). Tryptophan was the limiting amino acid, except in worker pupae, where sulfur amino acids were the limiting amino acids. The PDCAAS of late pupae drones (93.1%) was comparable to egg and casein, while their mean BV (78) exceeded that of workers (35.2). Therefore, drones in the larval or early pupal stage are a high-quality protein source, comparable to beef and superior to vegetable sources, with great potential for the production of various food products.
