摘要: 利用改型膨润土对红葡萄酒原酒进行澄清,主要考察了膨润土添加量、不同澄清时间以及不同pH条件下葡萄酒的澄清效果,结果表明:膨润土的最佳添加量为0.4g/L时即可达到良好的澄清效果;膨润土对葡萄酒的澄清在最初的8h内作用明显并且应尽可能在较低的pH条件下进行,这样就会有更多的蛋白质带正电荷,与带负电荷的膨润土表面产生电荷吸引,从而使蛋白质沉淀,有利于保持酒体的长期稳定。

Abstract: Modified bentonite was utilized to clarify red base wine.The effects of clarification of wine with the addition of bentonite,different time of clarification and different pH were investigated.The results showed that the wine presents opeimum effect when the addition of bentonite is 0.4g/L.The effects of clarification with bentonite were apparent during the first 8 hours and better with the condition of lower pH possibly due to more protein of positive charges under these conditions,to be adsorbed to the surface of bentonite to form precipitation.
