<p>Fine particles of gelatin and amino acid used in the present invention are particularly suitable for use in combination with resins. Gelatin particles used in the present invention have the number-average molecular weight of 8,500 or less, and amino acid partiles with the number-average molecular weight of 200 or less, so that efficient pulverization becomes possible and that gelatin and amino acid particles maintain their intrinsic properties as they are not subject to denaturation during pulverization. Resultant particles are neither too large nor too small but are uniform in size and are particularly suitable for use in combination with resins.</p> |
