Abstract
In this study the extraction of ganglioside from the lipid soluble fraction of sika deer antler was investigated using response surface methodology (RSM). A three-level Box-Behnken design which was based on the results of a single-factor test was employed to optimize the parameters for extraction of ganglioside. The experimental results were fitted with a second-order polynomial equation by a multiple regression analysis. By solving the regression equation and also by analyzing the response surface contour plots, the optimal ganglioside extraction conditions were determined: ratio of liquid to raw material 11, temperature 40°C and time 7min, and the maximum yield of ganglioside extraction was 1.25%.
