Lipid and protein structure analysis of frankfurters formulated with olive oil-in-water emulsion as animal fat replacer

► Lipid and protein structure of frankfurter with oil-in-water emulsion were studied. ► FT-IR was used to determine structural features of lipid and protein. ► Emulsions like pork backfat replacer were stabilized with soy protein. ► Structural characteristics could be associated with textural properties.
