Using ultra-fine pulverized peanut shells as raw materials, the effects of citric acid mass fraction, microwave processing time, and microwave power on the extraction rate of SDF were investigated. The box-Behnken experimental design and response surface analysis method were used to optimize the microwave-assisted ultra-fine pulverization. The SDF process for extracting peanut shells determines the best extraction conditions. The optimal extraction conditions for SDF are that citric acid mass fraction is 4.2%, microwave treatment time is 4.5min, microwave power is 400W and material-liquid ratio is 1:30. The yield and the purity of SDF is respectively 47.05% and 85.35%.
