Abstract:Cordyceps sobolifera was selected as raw material, the processing technology of cordyceps sobolifera  instant powder was studied. The addition of cellulase were optimized by orthogonal experiments. The Cordyceps sobolifera instant powder was prepared by removing contaminating proteins, homogenate, filtration and freeze-drying. Senses of instant powder, solubility, the active ingredient and hygiene indicators were tested. The experiment results showed that the optimal parameters were pH5, 50℃, cellulase 0.5%, 35min respectively. The wetness, dispensability and bulk density were 15.91s, 1s, 1.6737g/mL respectively. The content of polysaccharide and the total nucleoside were 473.57mg/g, 16.693mg/g respectively. The uridine , adenine and inosine were 2.1835mg/g, 0.6920mg/g, 0.8028mg/g.
