METHOD OF DETERMINING SOLUBILITY AND HARDNESS OF SOLID MILK, AND METHOD FOR PRODUCING SOLID MILK

摘要

To provide a solid milk having suitable solubility and high hardness, and a method of producing the same.SOLUTION: In the invention, a powder X-ray diffraction device is used to analyze an X-ray diffraction pattern of a surface 12 of solid milk and determine the solubility and hardness of the solid milk. The step for analyzing the X-ray diffraction pattern includes determining whether a main peak in the range of 2θ=10-15° is present in the range of 2θ=10-11° or 2θ=12-13°.SELECTED DRAWING: Figure 1
