Abstract:

In order to enhance the extraction efficiency of soybean paste flavor components, Plaekett-Burman design and response surface methodology were used to optimize extraction conditions. Eight factors were evaluated by Plackett-Burman design on the basis of total peak area and further optimization was performed by Box-Behnken experiments. Results showed that extraction temperature, extraction time and the addition amount of inorganic salts played important roles in the extraction of essential flavor components. The optimal extraction parameters were extraction temperature of 56 ℃, extraction time of 42 min and sodium chloride addition amount of 0.98 g. Under the optimal extraction condition, the total content of volatile flavor components was significantly improved according to the increase of total peak area from 12880000 to13107129.
