- Exploring the potential of Hermetia illucens larvae extracts : a promising approach for dermocosmetic formulationsPublication . Filipe, Márcia Santos; Cardoso, Rossana V.C.; Ayuso, Manuel; Murta, Daniel; Díaz-Lanza, Ana María; Rosado, Catarina; Pires, Tânia C.S.P; Calhelha, Ricardo C.; Rijo, PatriciaGlobally, the yearly disposal of 1.3 billion tonnes of food raises environmental and public health concerns. Black soldier fly (BSF) larvae present a sustainable solution, converting organic waste into nutrient-rich biomass. The extracted oil from BSF larvae, rich in fatty acids (FA), offers an eco-friendly alternative for the cosmetic industry. In this study, larvae sourced from a Portuguese company were fed olive pomace, a by-product of olive oil production. The lipidic sample extracted revealed a composition high in oleic acid, valuable for cosmetics. Investigating the biological activity of lipid extractions from larvae fed with olive pomace is a novel approach. Notably, the n-hexane ultrasound-assisted extraction method demonstrated potent antioxidant properties, and some extracts displayed antimicrobial activity. Five non-cytotoxic extracts; three with no relevant activity (IC50 from 236 to >400 μg/mL). These findings highlight BSF larvae as an environmentally friendly source of fatty acids, offering promising alternatives for diverse applications.
