Modulation of the lipolysis and subsequent antibacterial activity of the fat from black soldier fly (Hermetia illucens) by the combined selection of slaughtering, drying and defatting methods of the larvae

The aim of this study was to evaluate the modulating effect of the processing of Hermetia illucens larvae on the antibacterial activity of the fat related to lipolysis to free fatty acids (FFAs), mainly as lauric acid. Blanching and freezing were compared for slaughtering, oven or freeze-drying for...
