Abstract: Disclosed are whey protein-containing granules which can dissolve a whey protein into water without forming insoluble lumps thereby making a solution containing the dissolved whey protein clear without turbidity, and a method for producing the same. The whey protein-containing granules are composed of a polyglycerin fatty acid ester having HLB of 13 to 18 and containing lauric acid as a constituent fatty acid. As the polyglycerin fatty acid ester, for example, monolauric acid decaglycerin ester or monolauric acid pentaglycerin ester may be used.

Abstract: It is an objective of the present invention to provide a means for producing rapidly soluble granules with the use of any powdery raw material that is poorly sedimented in water and thus is dispersed or dissolved with difficulty in water. According to the present invention, a method for producing rapidly soluble granules, comprising mixing granules having poor sedimentation property in water and granules having good sedimentation property in water while adding an emulsifier thereto to thereby obtain mixed granules coated with the emulsifier.
