Abstract
Disclosed is a collagen powder and/or a collagen derivative powder, which are obtained by dispersing in a hydrophilic organic solvent a crude collagen precipitate which comprises 12 to 50% by mass of a collagen precipitate and/or a collagen derivative precipitate having an average particle size of 1 to 1,000 μm, recovering solids and then drying the solids. By dispersing the crude collagen precipitate in the hydrophilic organic solvent, the resulting precipitates can be dehydrated, so that drying of the thus obtained solids can be done by air-drying. In addition, the resulting collagen powder and/or collagen derivative powder exhibit excellent solubility due to an increased specific surface area and also have excellent ease of handling with the average particle size being 8 to 1,000 μm.
