This study investigated the lipid composition of edible insects (crickets and silkworms) and compared it with that of common food sources (beef, pork, chicken, wheat, soybeans, brown rice, and polished rice) to explore their potential as novel functional foods. Lipidomics, the comprehensive study of lipids, has advanced significantly, enabling the simultaneous measurement of hundreds of lipids using LC-MS/MS. Lyophilization was employed for meat samples before pulverization. Extracted lipids were dried, reconstituted, and then analyzed using a method developed by the Baker Heart and Diabetes Institute, allowing for the simultaneous analysis of 665 lipids within 16 minutes. Samples were measured five times, and data analysis was conducted using Mass Hunter Quantitative software and Mass Profinder Professional (MPP). MPP analysis identified 93 lipids common to all samples, with 12 lipids, including CE (16:0), CE (18:0), and LPE (17:0), unique to crickets and silkworms. Hierarchical classification clustered insect lipids closer to soybeans than animal meats. In conclusion, this study demonstrated the utility of MPP and Mass Hunter Quantitative software for the visual and powerful comparative analysis of complex lipidomes, highlighting the potential of edible insects as a rich source of diverse lipids.
