Physiological and biochemical aspects of using black lion fly larvae as a source of biologically active and nutrient substances

Introduction. Functional foods are products that, in addition to taste and nutritional value, have a physiological effect on the human body. ω-6 and ω-3 fatty acids, when consumed in the form of triglycerides from various food sources, undergo digestion in the small intestine, allowing absorption and transport into the blood and subsequent assimilation into the body, including the brain, retina, heart and other tissues. Amino acids must be obtained from food because the human body lacks the metabolic pathways necessary to synthesize some amino acids. In nutrition, amino acids are classified as essential and non-essential.
Aim. To determine the fatty acid and amino acid composition of black soldier fly larvae for use as a dietary supplement.
Materials and methods. In the experiment, the fatty acid and amino acid composition of the larvae of the black soldier fly (Hermetia illucens) was studied with the subsequent goal of using the insect as a component in dietary supplements. We assessed the amino acid and fatty acid composition of the larvae. Hermetia illucens were grown on four different diets; the group with the highest weight obtained was taken to determine the amino acid and fatty acid composition. To determine amino acids, Hermetia illucens were selected at the pre-pupa stage, dried in a SNOL 58/350 cabinet at 105 oC, and analyzed on an lc-20ad prominence liquid chromatograph. Amino acid analysis was carried out on an lc-20ad prominence liquid chromatograph, lysine 4.3%, valine 1.4%, leucine 4.6%, arginine 6.7%, isoleucine 2.8%, histidine 2.0%, methionine 2 were obtained %, phenylalanine 3.4%, tryptophan 1.7%, threonine 2.9%.
Results. Dried samples in a SNOL 58/350 cabinet at 105 °C were obtained by extracting the crushed mass of larvae with petroleum ether. The sample was examined on a Chromatek-Crystal 9000 chromatograph No.: 2191672 and contains lauric acid up to 53%, myristic acid 5%, palmitic acid 5%, oleic acid up to 5%, omega-3 and omega-6.
