Study of Decoloration Effect on Brown Mushrooms Dietary Fiber by H_2O_2

In order to improve the color of dietary fiber ofbrown mushrooms,to improve product quality,the dietary fiber decoloration was studied by H2O2 using orthogonal test,the effects of concentration of H2O2,decolonization time,liquid ratio on impact of decolonization were discussed.The results showed that the best process parameters to decolonization brown mushrooms dietary fiber were:concentration of H2O25%,time 4 h and liquid ratio 1∶7.After decoloration,the swelling force,water retention and hydration water power of dietary fiber of brown mushroom were all improved.
