Title:
NANOPARTICLES AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/241562
Kind Code:
A1
Abstract:
The present invention relates to nanoparticles characterized by containing, on a solids basis, 1% by weight or more of at least one animal protein selected from the group consisting of whey protein, gelatin, collagen, and decomposed products thereof and 0.001% by weight or more of an electrolyte, and in that the weight ratio on a solids basis between the animal protein and the electrolyte (electrolyte/animal protein) is 0.001-1.0, and the average particle size is 10-300 nm. The nanoparticles according to the present invention are nanoparticles containing a reduced amount of catechin compared to conventional particles and using a cheaper electrolyte, and can stably retain a biologically active substance.
