| Abstract: | To further improve the extraction technology of red koji pigment,red kojic rice is taken as a raw material to be tested.Based on the principle of Central-Composite test design,the parameters of red koji pigment extraction were analyzed and simulated with BP neural network,and optimized by genetic algorithm.The optimal extracting conditions were indicated as follows：alcohol concentration 69%,pH4.4,extracting temperature 69℃ and extracting period 75 min.The absorbency of the extract liquid could reach 0.216 under the above conditions. |
