Nutritional value of black soldier fly (Hermetia illucens) larvae (BSFL) processed by three different methods of treatment was compared. The resulting products were the spray-driedBSFL (SPR), oven-dried BSFL 1 (OVN1) and oven-dried BSFL 2 (OVN2). Proximate chemical composition, and profiles of amino acids, fatty acids, minerals, heavy metals, vitaminsand nucleotides were analysed and compared. The tested BSFL meals were considered tohave a good profile of essential amino acids (EAAs), with leucine, lysine, valine, and histidine being the dominant EAAs. Their content of saturated fatty acids exceeded that of theunsaturated fatty acids. Vitamins B1, B2, and C were also present in the samples. Mineralssuch as calcium, potassium, phosphorus, sodium, magnesium, zinc, iron, manganese andcopper were found to be in adequate amounts in almost all the samples. Heavy metals inthe BSFL meals were mostly below 1g kg-1. Nucleotides such as inosine monophosphateand uridine monophosphate occurred in all the BSFL meals. Other nucleotides, includingguanosine monophosphate, adenosine monophosphate, xanthosine monophosphate, andcytidine monophosphate were detected in either or both of SPR and OVN2. In general, thenutritional value of the BSFL meals tested in the present study was influenced by themethod of processing.
