Morphological examination assigned the specimens to the genus\n                    <jats:italic>Gryllus<\/jats:italic>\n                    while suggesting possible divergence from currently described species. Protein content calculated using chitin-corrected nitrogen reached 61.48\u202fg\/100\u202fg dry matter, providing an improved estimate of true protein content. Total fat was 11.65\u202fg\/100\u202fg, while ash 5.01\u202fg\/100\u202fg and dietary fiber 7.43\u202fg\/100\u202fg, indicating limited discriminatory power of proximate composition alone. The mineral profile showed elevated macro-elements, particularly K (1,037.50\u202fmg\/100\u202fg), P (915.00\u202fmg\/100\u202fg), and Ca (313.75\u202fmg\/100\u202fg), while\n                    <jats:italic>\u03b1<\/jats:italic>\n                    -tocopherol (23.80\u202fmg\/100\u202fg) and vitamin C (11.64\u202fmg\/100\u202fg) revealed a distinctive micronutrient pattern. The essential amino acid profile yielded an EAA\/TAA ratio of 56.51%, supporting favorable protein quality; however, Lys (34.78\u202fmg\/g protein) was identified as the first limiting amino acid relative to FAO reference patterns, differing from limitation patterns reported for other\n                    <jats:italic>Gryllus<\/jats:italic>\n                    species. The lipid fraction was dominated by linoleic (34.29%) and oleic acids (30.66%), resulting in favorable cardiometabolic indices characterized by low atherogenicity (0.63) and thrombogenicity (0.53). Overall, the nutritional profile confirms the potential of\n                    <jats:italic>Gryllus<\/jats:italic>\n                    sp. as a high-quality protein source with favorable lipid quality indices and a potentially favorable cardiometabolic fatty acid profile. Comprehensive nutritional profiling therefore represents a useful complementary approach for the characterization of edible cricket materials.\n
