This study evaluated breast meat quality of broiler chickens following dietary inclusion of full-fat Black soldier fly (Hermetia illucens) larvae (BSFL) sourced from three food-waste production sites in a nutritionally balanced diet. Broilers were fed diets containing 0%, 3%, 6%, or 9% BSFL sourced from 3 different facilities in a 3 × 4 factorial design. At 42 days of age, breast meat samples were collected for evaluation of physicochemical traits, chemical composition, amino acid, and fatty acid profiles. Inclusion of dietary BSFL had no adverse effects on key meat quality parameters, including water-holding capacity, pH, color, cooking loss, or shear force. Breast meat protein content increased significantly in broilers fed the 9% BSFL diet compared with the control, while essential amino acid composition remained unchanged across treatments. In contrast, BSFL inclusion substantially modified the fat profile of breast meat, characterized by enrichment of short- and medium-chain saturated fatty acids, increased eicosapentaenoic acid, reduced ω-6 polyunsaturated fatty acids, and an improved ω-3/ω-6 ratio. These results demonstrate that food-waste-derived full-fat BSFL can be incorporated into broiler diets at levels up to 9% without compromising breast meat quality, while enhancing its nutritional fat profile and protein content.
