Abstract: The influence of bean color change is studied along with the change of adding alkaline quantity and heating time.Through testing the experiment sample for two weeks preservation after handling, the chromaticity difference between beforeand after handling is calculated. The bean mathematics model of color change is gained using the second general revolvingcombination design. The significance inspection for equation shows the confidence degree of regression equation is 0.95; fittingresult is good, which can offer certain theory foundation for the following production. The mathematics model gaining fromsecond general revolving combination design is optimized by genetic algorithm. The population size is 20, crossover probabilityis 0.7, and mutation probability is 0.04. Via the evolution of 100 generations, the optimization solution is gotten, which can offercertain theory foundation for the following production.
