摘要
Abstract
In order to improve the extraction rate of flaxseed oil, response surface methodology was used to optimize the extraction conditions of flaxseed oil using n-hexane as the solvent. The effects of extraction temperature, extraction duration, solid- to-solvent ratio and stirring speed on the extraction rate of flaxseed oil were investigated by one-factor-at-a-time experiments. A quadratic polynomial regression model was fitted using a four-factor, three-level Box-Behnken design and analyzed using response surface methodology to obtain the optimal extraction conditions： temperature 56 ℃, solvent-to-solid ratio 8：1 （mlJg）, stirring speed 310 r/min, and extraction time 2.2 h. Under these conditions, the extraction yield of flaxseed oil was 98.12%, closed to the theoretical value of 98.28%. In conclusion, the optimized extraction conditions are reliable.关键词
