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。

And adsorption of jack bean proteins onto the amphoteric resin was studied in this paper. The amphoteric resin was in innersalt form. The results of adsorption experiments show that when the proteins are adsorpted into the amphoteric resin in the neutral phosphate buffer solution, the diffusion coefficient of protein is near twofold in 0.4 mol/L NaCl phosphate buffer solution than that in solution without salt, and the adsorption capacity of protein also rises at the same ti...

通过盐浓度对吸附的动力学和热力学影响的研究，结果表明，在中性磷酸盐缓冲液中，两性树脂吸附刀豆蛋白，有盐( 0 。4mol/L Na Cl)的比无盐的扩散系数提高将近一半，且吸附量增加，其吸附等温线的效率在最初始部分高于无 Na Cl时的；随着盐浓度( 0～ 1 mol/L Na Cl)的提高，树脂对蛋白的吸附量也变大，盐浓度提高时树脂膨胀体积的增大与蛋白吸附量的增加呈线性关系，内盐型两性树脂对大分子蛋白质的吸附作用与小分子高价离子的相似，同样是通过内盐键破裂吸附。
