Abstract
PURPOSE: Polysaccharides in a culture medium resulting from fermentation is made transparent by treating with a relatively high-concentration oxidant and then treated with a reducing agent to produce a fermentation gum of high transparency in a short time.
CONSTITUTION: On a cluture mixture where gummy polysaccharides have been produced by fermentation, is made to act 0.1W2%, based on the total weight of the culture mixture, of sodium hypochlorite for a prescribed time. Then, 0.05W4% of at least one selected from sodium sulfite or sodium borohydride is added. Or 0.1W5%, based on the total weight of the culture mixture, of caustic soda and/or caustic potash and at the same time, or after reaction for a short time, 0.01W1% of sodium hypochlorite are added to effect the reaction for a prescribed time, and 0.005W2% of at least one selected from sodium sulfite or sodium borohydride is added in the presence of a small amount of an inorganic acid.
