Provided are an emulsifier derived from sugar polymer capable of successfully emulsifying even unsaturated oil, a production method therefore, and a production method for emulsion using the emulsifier. This emulsifier can be obtained by a production method including an emulsification improving step of improving the emulsification of sugar polymer particles dispersed in water. In this emulsification improving step, the emulsification of sugar polymer particles can be improved by an action of an emulsification aid that is at least water-soluble one kind selected from salts, an amphiphilic agent, saccharides, an organic acid, and an amino acid. Alternatively, the emulsification of sugar polymer particles can be improved by storing the sugar polymer particles dispersed in water at a low temperature of 10° C. or lower. |

1. An emulsifier consisting of: water; sugar polymer particles dispersed in the water; and an emulsification aid dissolved in the water and improving emulsification of the sugar polymer particles,
wherein a hydration layer is formed around the sugar polymer particles dispersed in the water, wherein the particle size of the sugar polymer particles is 50 to 800 nm, and wherein the sugar polymer constituting the sugar polymer particles is (a) a sugar polymer produced by a microorganism using, as a component, saccharides selected from monosaccharides; (b) an unmodified natural polymer; (c) methyl cellulose, ethyl cellulose, methyl hydroxypropyl cellulose, carboxymethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, sodium carboxymethyl cellulose, propylene glycol alginate, a cellulose crystal structure, a starch/sodium acrylate graft polymer, hydrophobized hydroxypropyl methylcellulose; or (d) polyvinyl alcohol, polyvinyl pyrrolidone, carboxyvinyl polymer, polyacrylate, or polyethylene oxide. |
