There were many reasons attributed to this phenomenon: macromolecules, which were from raw material such as polysaccharides and proteins decomposed incompletely in the process, formed precipitation through biochemical reaction, many kinds of bacteria were not removed totally after fermenting, which caused bacterial precipitation, Fe3+ from fermenting equipments combined with polyphenol and proteins to form infusibility complex.

中文摘 要：食醋在其保质期内经常出现混浊现象，其原因主要有：原料中的大分子物质，如多糖、蛋白质等分解不彻底，后经过生化反应形成沉淀物质；发酵完成后，食醋中的各种微生物未及时清除，从而造成的菌体性沉淀；以及由于生产设备中的Fe3+与原料中的多酚、蛋白质等大分子形成的不溶性络合物所造成的沉淀。
