摘要:
双极膜电酸沉技术在分离提取大豆分离蛋白方面具有广阔的应用前景，同时该技术也存在易受蛋白污垢影响的缺点。比较了在没有外加物质的影响下，双极膜电酸沉技术与化学酸沉法提取大豆蛋白的效果；分析了双极膜间残留蛋白质及其对双极膜提取速率的影响。结果表明：双极膜电酸沉技术比化学酸沉法更具优势；双极膜提取速率随酸沉程度的增加而降低，在连续电酸沉4次后，膜间残留的蛋白质对双极膜提取速率造成显著性影响。
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.
