[en] Objectives: To determine the physicochemical properties of the oil obtained from Tenebrio molitor Larvae and explore its potential as edible oil.
Methodology: Oils obtained from five batches of Tenebrio molitor Larvae were investigated. Among the samples, three were produced directly in the lab (3 different productions) and 2 were purchased from a local supplier. In addition to the total lipid content (solvent extraction), both FA (GC) and TAG (HPLC) profiles were determined. Thermal properties by DSC were also estimated.
Results and conclusion: The fresh Larvae from the lab contained 52% of total proteins (% dry matter). Their total fat content was around 36% (% dry matter). The commercial samples contained more proteins, but less fat: around 58% of total proteins and 30% of total fat (% dry matter). All the extracted oils contained high amount of unsaturated fatty acids. However, the chemical composition and the thermal properties of the samples varied according to their origin. The level and quality of lipid content offer potential as a substitute of oilseeds.
