  • Publication number: 20250017236
    Abstract: One problem addressed by the present invention is to provide an emulsion composition that maintains its quality even when stored frozen. The problem is solved by a protein that satisfies one of the following conditions (A) to (C) and is partially in the state of particles when made into an aqueous dispersion: (A): having at least one peak in a region of a molecular weight of 66,000 or more in terms of polyethylene glycol in a gel filtration chromatography elution curve; (B): having a weight-average molecular weight of more than 27,000 in terms of polyethylene glycol as measured by gel filtration chromatography; and (C): having a number-average molecular weight of more than 3,500 in terms of polyethylene glycol as measured by gel filtration chromatography.

  • Publication number: 20230172223
    Abstract: The object of the present invention is to provide an emulsion composition that maintains emulsion stability even after high temperature process such as sterilization (heat resistance), shows a small change in particle size distribution between before and after heating, and maintains emulsion stability even under conditions where transformation of an oil phase component (for example, solidification or crystallization of the oil phase component due to temperature drop, or melting of the oil phase component due to temperature rise) occurs (temperature drop resistance), wherein the composition is easily handled during the production process. The object is solved by an oil-in-water emulsion composition containing solid particles, a predefined surfactant, an oil phase component, and an aqueous phase component, wherein the oil phase component includes a predefined oil component and the solid particles are distributed along the interface between the oil phase component and the aqueous phase component.
