 Different extraction methods with their advantages and limitations for extraction of nutrients from insects.

Extraction methodTarget insects (examples)Extraction yieldProtein denaturationEnergy consumptionAdvantagesLimitationsReferences
Supercritical fluid extraction (SFE)H. illucens, T. molitorModerate (mainly lipids)LowHighSolvent-free, selective extraction preserves protein functionalityHigh capital and operational costs, limited protein recovery[102]
Solvent-based extractionA. domesticus, T. molitorHighModerate to highModerateHigh protein yield, established technologySolvent residues, environmental concerns, protein denaturation[103]
Mechanical & physical methodsH. illucens, grasshoppersLow to moderateLowLowSimple, cost-effective, scalableLower extraction efficiency, limited fractionation[22, 104]
Enzymatic hydrolysisA. domesticus, H. illucensHigh LowModerateImproved digestibility, bioactive peptide productionEnzyme cost, process optimization required[27]
