PCT No. PCT/JP83/00338 Sec. 371 Date Jun. 19, 1984 Sec. 102(e) Date Jun. 19, 1984 PCT Filed Oct. 12, 1983 PCT Pub. No. WO84/01492 PCT Pub. Date Apr. 26, 1984.The present invention concerns a method for improving the solubility of gelling agents hardly soluble in water such as agar-agar, gelatin and carrageenan. Said method includes the step of contacting said gelling agent with a non-equilibrium plasma formed by applying a high frequency wave to a low pressure gaseous atmosphere, such as air, oxygen, carbon dioxide or nitrogen, and thereby obtaining a gelling agent readily soluble in water.
