Formulation and characterization of liposomal encapsulated systems of bioactive ingredients from traditional plant mountain germander (Teucrium montanum L.) for the incorporation into coffee drinks

•Echinacoside and verbascoside were dominant phenolics of mountain germander.•High encapsulation efficiency of extracted phenolics into liposomes was achieved.•Liposomes coated with biopolymers provided desirable in vitro digestion release.
