Abstract:
Bipolar membrane electro-acidification(BMEA)has a wide-ranging application potential in production of soybean protein isolate，although with the disadvantage of the susceptibility to blocking.In this study，chemical acidification and BMEA for precipitation of soybean proteins were compared without additive in the soybean protein concentrate(SPC)，the effect of the spacer fouling on the efficiency of BMEA was evaluated by one-factor analysis of variance.The result showed that BMEA precipitated more soybean proteins than chemical acidification，the ash content of the electro-acidified samples was lower than that of the chemical acidified samples，the efficiency of BMEA decreased as the concentration of the isolated protein increased，and the spacer fouling(P＜0.05)had a significant effect on the efficiency of BMEA after electro-acidifing 4 times successively.
