    • A method of treating wine, comprising introducing crude wine to both the dilution and concentration chambers of an electrodialysis apparatus; operating said apparatus so that the potassium concentration of the wine in the dilution chamber falls to below 500 mg/liter and the potassium content of the wine in the concentration chamber is increased into the range 1000 to 2000 mg/liters; cooling the wine from the concentration chamber to below 10.degree. C and adding tartaric acid crystals to said wine in order to adjust the pH into the range of 2.8 to 3.2 thereby precipitating tartar; separating the tartar from the wine and admixing said wine with wine emerging from the dilution chamber of the electrodialysis apparatus in a ratio such that the potassium content of the resulting mixture is below 500 mg/liter.
    • 一种处理葡萄酒的方法,包括将粗酒引入电渗析装置的稀释和浓缩室; 操作所述装置,使得稀释室中的葡萄酒的钾浓度降至500mg /升以下,浓缩室中酒的钾含量增加到1000-2000mg /升; 将葡萄酒从浓缩室冷却至10℃以下,并将酒石酸晶体加入到所述葡萄酒中,以将pH调节至2.8至3.2的范围,从而沉淀出牙垢; 将酒石与葡萄酒分离,并将所述葡萄酒与电渗析装置的稀释室中出现的葡萄酒混合,使得所得混合物的钾含量低于500mg /升。

    • Lactoferricin (Trade Mark), also called LFCIN (Trade Mark), a potent antimicrobial peptide, is produced by contacting an enzymatic hydrolysate of bovine lactoferrin or any mixture of peptides containing lactoferricin preferably with a butyl moiety-containing hydrophobic interaction chromatography medium, or alternatively with a carboxymethyl moiety-containing cation-exchange chromatography medium, rinsing the medium to remove unbound peptides, desorbing the lactoferricin solution at constant pH, and desalting the desorbed solution. The utility of the process is illustrated, for example, as follows. An enzymatic hydrolysate of bovine lactoferrin (600 g) was contacted with 3000 ml of BUTYL-TOYOPEARL 650M, the medium was rinsed with water, and then with McIlvaine (citric acid-sodium phosphate) buffer at pH 7.0., and lactoferricin was desorbed with McIlvaine buffer at pH 5.0. The desorbed material was desalted by contacting it with BUTYL-TOYOPEARL 650M, rinsing the medium with water to remove the buffer salts, and desorbing the lactoferricin with 10 mM HCl. A yield of 10.5 g of 99% purity was obtained. The product has applications as a safe and effective antimicrobial agent for use in oral hygiene products, cosmetics, clinical foods, etc.
    • 通过使牛乳铁蛋白的酶水解物或含有乳铁蛋白的任何混合物优选与含有丁基部分的疏水相互作用色谱介质接触来产生乳铁蛋白(商标),也称为LFCIN(商标),其是有效的抗微生物肽。 用含有羧甲基部分的阳离子交换层析介质,漂洗培养基以除去未结合的肽,在恒定pH下解吸乳铁蛋白溶液,并脱盐解吸溶液。 该过程的实用性例如如下所示。 将牛乳铁蛋白(600g)的酶水解物与3000ml BUTYL-TOYOPEARL 650M接触,用水冲洗培养基,然后用pH 7.0的McIlaine(柠檬酸 - 磷酸钠)缓冲液洗涤,并用乳糖铁蛋白溶解 McIlvaine缓冲液pH 5.0。 通过与BUTYL-TOYOPEARL 650M接触将脱附的物质脱盐,用水冲洗培养基以除去缓冲盐,并用10mM HCl解吸乳铁蛋白。 得到10.5g 99%纯度的产率。 该产品作为安全有效的抗微生物剂应用于口腔卫生用品,化妆品,临床食品等。
