Dilution of the filtrate with water gave a yellow precipitate ( B), this is the main-product ( ⅰ). 滤出(Ⅱ)后以水稀释残液时又析出另一种沉淀,这才是(Ⅰ)。
The Causes and Preventing Measures of Yellow Rice Wine Turbid and Precipitate 黄酒混浊沉淀的原因及防止措施
Non-biological turbidity and precipitate easily occurred in yellow rice wine on shelf. The mechanism of precipitate formation mainly covered protein precipitate, iron precipitate and oxidation precipitate. 黄酒产品在货架期容易发生非生物浑浊和沉淀,浑浊沉淀形成的机理主要有蛋白质沉淀、铁沉淀和氧化沉淀。
Cerous iodate is soluble in acidic aqueous solution, but a yellow precipitate is formed homogeneously and gradually after irradiation by laser. 三价铈的碘酸盐能溶于酸性永溶液,而在激光辐照后,却均匀地、逐渐地生成黄色沉淀。
Determination of Proteins in Yellow Rice Wine and Investigation on the Causations of the Precipitate 黄酒蛋白质的测定及其沉淀原因探讨
, white floc ( induced by the change of dissolution conditions of ethyl oleate, ethyl palmitate, ethyl linoleate and fusel oil), brown yellow precipitate ( induced by iron ion), and greasy substances ( produced by aroma-producing substances in liquor). 白色絮状沉淀主要由3种高级脂肪酸乙酯,即油酸乙酯、棕榈酸乙酯、亚油酸乙酯和杂醇油的溶解条件变化而引起;棕黄色沉淀主要是由铁离子形成的棕色沉淀物质;
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;
Icy apple fruit wine was produced by fresh apple juice and Angel fruit wine yeast. The wine had stable quality and was golden yellow in color and transparent and clean with no precipitate. 采用鲜苹果汁、安琪果酒酵母发酵生产冰爽苹果酒,成品质量稳定,酒色金黄、澄清透明、无沉淀;
Yellow rice wine contained multiple amino acids, amylum, dextrin, caramel color and colloid particle. Temperature change would make wine in unstable state such as color turbidity and precipitate caking. 黄酒中含有多种氨基酸、淀粉、糊精、焦糖色、胶体颗粒等,温度变化会使酒出现不稳定状态,如色泽浑浊、沉淀结块。
