Identification and physicochemical characterization of TFENs. (A) TFENs were isolated and purified by differential centrifugation and sucrose gradient ultracentrifugation. (B) TEM image (scale bar = 200 nm) and (C) hydrodynamic particle size of TFENs. The main components in TFENs (D) total lipids (E) proteins in SDS-PAGE gel (F) protein summary (G) polyphenols, and (H) flavonoids.
