flocculent precipitate

this study utilizes the supermolecular feature of lignin and modifies it. the surface groups of modified lignin action macromolecule protein, were removed them as flocculent precipitate thereby to increase non-biological stability of beer.

利用木素的超分子特性，并通过改性而使其表面基团与高分子蛋白质作用，进而将其絮凝沉淀除去，从而提高啤酒的非生物稳定性。

Liquor turbidity and precipitate include white haze, flocculent precipitate, white needle-shaped crystal, brown precipitate, faint yellow precipitate, blue precipitate and smoky haze etc.

白酒浑浊沉淀现象有白色浑浊、絮状物沉淀、白色针状结晶、棕色沉淀、淡黄色沉淀、蓝色沉淀、烟雾状浑浊等；

The results showed that, the white flocculent precipitate was the residues of polyacrylamide.

结果表明，白色絮状沉淀为聚丙烯酰胺在地层中的残留物。
