| abstract |
A process for improving the solubility of difficultly water-soluble gelling agents such as agar-agar, gelatin, or carrageenin, which comrpises bringing the gelling agent into contact with a so-called non-equilibrium plasma generated by high-frequency irradiation of a low-pressure gas atmosphere such as air, oxygen, carbon dioxide or nitrogen causing no hygienic problems. The resulting gelling agent is readily water-soluble. |
