Abstract
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 particles 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.
Claims3
A gelatin particle mixture comprising:
- a) a gelatin particle mixture including 0 to 10 weight % of gelatin particles having a size range of 9.0 .mu.m and larger;
- b) said gelatin particle mixture including 0 to 10 weight % of gelatin particles having a size range of 1.5 .mu.m and smaller;
- c) said gelatin particle mixture including more than 80 weight % of gelatin particles having a size range larger than 1.5 .mu.m and smaller than about 9.0 .mu.m;
- and
- d) wherein said gelatin particles in said gelatin particle mixture are pulverized into said size ranges from a gelatin starting material having an average molecular weight of less than 8500 daltons.
