Abstract

An embodiment of the present invention relates to protein granules containing a whey protein as a main component, the protein granules having an average particle diameter of 207 μm to 570 μm, a homogeneity U of 0.58 or less, a content ratio (volume ratio) of coarse powder having a particle diameter of 500 μm or more of 22% or less, and a content ratio (volume ratio) of fine powder having a particle diameter of 150 μm or less of 31% or less.

First claim

The invention claimed is:

1. Protein granules comprising a whey protein as a main component,
wherein the protein granules have an average particle diameter of 207 μm to 570 μm, a homogeneity U of 0.58 or less, a content ratio (volume ratio) of a coarse powder having a particle diameter of 500 μm or more of 22% or less, and a content ratio (volume ratio) of a fine powder having a particle diameter of 150 μm or less of 31% or less, and
wherein the average particle diameter, the homogeneity U, the content ratio (volume ratio) of the coarse powder having a particle diameter of 500 μm or more, and the content ratio (volume ratio) of the fine powder having a particle diameter of 150 μm or less, are determined by the following measurement method:
1. A volume-based particle size distribution in which data is plotted with the particle diameter as a horizontal axis and with a content ratio of particles as a vertical axis is obtained for the granules by a laser diffraction and scattering measurement method,
2. The average particle diameter and the content ratio (volume ratio) of the coarse powder and the content ratio (volume ratio) of the fine powder are determined from the volume-based particle size distribution, and
3. The homogeneity U is determined by the following formula (1),
