The galangal polysaccharide is dispersed in water to obtain a water phase; the corn oil is mixed with the water phase, emulsified by shearing, and homogenized to obtain an emulsion. The total sugar content of the galangal polysaccharide is >70%, and the molecular weight is 4×10 4 -1×10 5 Da, composed of seven monosaccharides: mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose and arabinose, the proportion of galacturonic acid > 10%, and the proportion of galactose > 38% %, arabinose accounts for more than 22%, and has good emulsifying properties. The emulsion can effectively delay lipid digestion.
