Abstract
Highlights • The emulsification and stabilization properties of polysaccharide fraction of spruce extract (galactoglucomannans, GGM) was studied. • GGM exhibited good to excellent emulsification and stabilization at five GGM to oil ratios. • About one-tenth of the starting material weight was concentrated at the droplet interface. • The interfacial properties in emulsions were similar from GGM to oil ratios 2 to 0.4. • The possible effect of macromolecular properties of the adsorbed GGM on the interfacial saturation is discussed.
