Abstract
This study was conducted to optimize hot water extraction process of cordyceps militaris for development beverage. Optimal condition for hot water extraction was investigated with changes in extraction concentration and temperature by response surface methodology. The content of soluble solid was effected with concentration. The efficiency of extraction for turbidity, total sugar, reducing sugar and protein increased with low concentration. The response variables had significant with concentration and the established polynomial model was suitable (p>0.05) model by lack-of-fit analysis. Optimal extraction conditions as the limited renditions of 2.0∼2.4% extractable solids, 1.5∼2.0% brix, l14∼120 $\mu\textrm{g}$/g total sugar, 10.5∼11.0 $\mu\textrm{g}$/g reducing sugar and 110∼l15 $\mu\textrm{g}$/g protein were 95∼100$\^{C}$ and 4.0∼4.1% of concentration.
