| Abstract | ||
| Black soldier fly (BSF, Hermetiaillucens L.) larvae are among the most productive species because of their nutritional advantages and minimal environmental effect. They are not regarded as pests and can be reared and harvested without specialized infrastructure. Additionally, depending on the substrate they consume, they can transform organic waste into beneficial biomass, such as proteins, lipids, and chitin, with varied compositions. In this study, larvae were raised on restaurant waste, which included fried food (such as chicken, meat, and fish), potato peels, carrot scraps, rice, and bread remnants. Larvae samples were frozen and dried for proximate analysis, where protein content, lipid content, moisture content, flavonoids, phytic acids, amino and fatty acid profiles, mineral content, and microbiological properties of BSFL were evaluated. According to the results, the dry base BSF biomass included 33.90% crude protein, 45.37% fat, 0.95% phytic acids, and 12.43% fiber. In addition to the total flavonoids reaching 892.4 ppm, the moisture content reached 66.00%. The amino acids that are essential present in the highest concentrations were phenylalanine, leucine, and lysine, whereas glutamic acid and alanine were considered non-essential amino acids. Lauric acid was identified as the main saturated fatty acid and oleic acid as the most prevalent unsaturated fatty acid. Sodium (Na) was the most abundant mineral in BSF larvae (40%). This study emphasizes the importance of this insect as an alternative protein source, in addition to its utilization as a substitute for protein-rich feedstuff in chicken feed production. | ||
