Monitoring of Chemical Changes in Explosively Puffed Ginseng and the Optimization of Puffing Conditions

Response surface methodology was used to predict the optimum conditions of explosive puffing process for ginseng. A central composite design was used to monitor the effect of moisture content and puffing pressure on dependent variables such as functional compounds (extract yield, crude saponin, acidic polysaccharide, and total phenolic content)and sensory properties. Correlation coefficients (R2) of models for crude saponin, acidic polysaccharide, and total phenolic content were 0.9176 (p
