The rheological properties in the supernatant of peach gum from Prunnus dulcis were discussed in order to provide more scientific technical parameters and references for developing peach gum as a kind of medicinal gum. The rheological properties in the supernatant of peach gum were comparatively studied in different material ratios, temperatures, shaking times, pH values and salinities. The results show that, 1) the mathematical model of shear rate with material ratio and shear stress is Y=0.069X12+0.035X 2 -1.174, R2=0.942; 2) the mathematical...
