| Abstract: | Rapeseed cake is a good raw material of extracting phytic acid,and phytic acid has unique biological activities.The solution of potassium oxalate was used to extract phytic acid from rapeseed cake.On the basis of single factors experiments,the extraction technic was optimized by response surface methodology,and a quadratic polynomial mathematical model was established.The optimal conditions were as follows: pH 8,ratio of liquid to solid 14∶1,concentration of potassium oxalate 0.075 mol/L,extraction time 5 h.Under the optimal conditions,the yield of phytic acid was 1.81%. |
