Although the mealworm larva (Tenebrio molitor) is high protein source, aversion feature of the larva made it difficult for consuming as a food. In this study, we established optimal powder manufacturing process for T. molitor larva for using as a novel food. For this purpose, it should be feed with the bran sterilized by water vapor for 3-5 days, starved without water or food for 3 days, and then the larvae were sterilized before freeze-drying. The sterilized T. molitor was lyophilzed and grinded by a blender. A safety of the powder as a food was validated by evaluation of Raw 264.7 macrophage cytotoxicity using MTS assay. As above results, we propose that optimal powder manufacturing process established in this study can be used in industrial production of T. molitor as a novel food.
