Abstract: There is provided a method for treating an aqueous solution of soybean protein to provide a calcium abundant bean soup drink. The method comprises the steps of adding endpeptidase to an aqueous solution of soybean protein the protein of which has been thermally or alkali denatured, causing the components of the mixture to react with each other under intense agitation, adding calcium salt to the reaction product and optionally adding oil and emulsifying agents to the resulting mixture and homogenizing the mixture.

Abstract: 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.

Abstract: A novel method for improving the quality of wheat flour, wherein the novelty resides in bringing the wheat flour into contact with a non-equilibrium plasma. The dough prepared from the wheat flour processed by this method exhibits an improved viscoelasticity, and the starch in this wheat flour shows a greater water holding capacity. Appearance and texture of the secondary products from this wheat are also improved remarkably.

Abstract: A complex personal dosimeter including a gamma- and beta-ray dosimeter block and a neutron dosimeter block. These two blocks are enclosed in a badge case type package so that a person can secure the dosimeter on his clothing. The gamma- and beta-ray dosimeter block consists of four thermoluminescent elements in combination with plastic filters having different thickness. The neutron dosimeter block consists of four thermoluminescent elements in combination with cadmium and tin filters. This complex dosimeter can individually measure or estimate the radiation doses such as gamma-rays, beta-rays, thermal neutrons, epithermal neutrons and fast neutrons over a wide range of doses, and can also obtain information on the energy of the radiation.
