TEM and Cryo-TEM micrographs of food derived micro/nano-particles TEM images: magnification × 10000, scale bar “▬” as 200 nm; a: porcine bone soup MNPs; b: UF-MNPs isolated from porcine bone soup; c: SEC-NPs isolated from porcine bone soup. Cryo-TEM images: magnification × 8000; d: porcine bone soup MNPs, scale bar “▬” as 500 nm; e: UF-MNPs isolated from porcine bone soup, scale bar “▬” as 500 nm; f: SEC-NPs isolated from porcine bone soup, scale bar “▬” as 500 nm. Green arrows: particles with diameter of 40~100 nm; Red arrows: particles with diameter of around 250 nm
