运用植酸降低西凤酒固形物的研究

Study on Application of Phyticacid to Reduce the Solids in Xifeng Liquor

植酸对金属离子极具螯合力 ,形成植酸复盐络合物沉淀 ,除去酒液中金属离子。通过在不同酒度、不同固形物含量、不同除浊工艺处理的西凤酒中进行添加量、酒体理化分析的试验表明 ,在西凤酒中添加植酸可明显降低西凤酒固形物含量 ,且对酒质有一定改观 ,不同酒质植酸添加量是不同的 ,植酸添加量随酒中固形物含量增大而增大 ,但在西凤酒中植酸添加量不应超过0.4‰

Phyticacid could remove metal ions in liquor by its specific chemical property of integrating metal ions into phytate complex precipitate. We added phyticacid into various Xifeng Liquor (with different alcohol content, different solids content and managed by different precipitate-removing techniques) and then analyzed the physical and chemical indexes of the liqour body. And the results suggested that the addition of phyticacid in Xifeng Liquor could effectively reduce the solids and improve the liquor quality and the using quantity varied according to the liquor itself (the using quantity increased when the solids content increased but the adding quantity should be less than 0.4% in Xifeng Liquor).
