The insolubles formed in biodiesel blends can cause operation problems because they can plug the fuel lines and filters. The formation of insolubles in soybean oil (SBO‐), yellow grease (YG‐), and palm oil (PO‐) based biodiesel blends after cold soaking at 4 °C was investigated. PO‐based biodiesel blends displayed a much higher time to filter (TTF) and greater insoluble mass, compared to SBO‐, and YG‐based biodiesel blends. Fourier transform infrared (FTIR) spectra and gas chromatography‐flame ionization detector (GC‐FID) chromatograms indicated that PO‐based biodiesel insolubles can be attributed to monoglycerides, while SBO‐based biodiesel insolubles are due to steryl glucosides (SG). A simple analytical method for identification of SG in biodiesel samples was established by GC‐FID.
