    • The present invention relates to a process of enriching one target compound from a liquid, which process comprises at least one step of isolation performed by differentially partitioning between two aqueous phases. In the present invention the phases are formed by adding a thermally responsive, self-associating (i.e. clouding) hydrophilic polymer, and if needed some additional salts, to an aqueous biotechnical solution (such as a fermentation sample or bioseparation process stream) under thermal and other conditions where the solution separates into a one polymer, two-phase system with one phase enriched in the polymer. The target compound is to be found in the phase not enriched in the polymer, while a significant though varying percentage of contaminants may differentially partition to the phase interface or the polymer enriched phase. With minor or no modification the target containing phase solution can be further processed via standard unit operations such as precipitation, chromatography, and filtration to further purify target and remove any residual polymer.
    • 本发明涉及从液体中富集一种目标化合物的方法,该方法包括通过在两个水相之间进行差异分配而进行的至少一个分离步骤。 在本发明中,通过将热响应,自缔合(即,混浊)的亲水聚合物和如果需要的话添加一些额外的盐,在热和/或热处理下,向水生物技术溶液(例如发酵样品或生物分离工艺流) 溶液分离成一种聚合物的其它条件,两相体系中一相富集聚合物。 目标化合物可以在不富集聚合物的相中找到,而显着的不同百分比的污染物可以差异地分配到相界面或聚合物富集相。 通过微量或不改变,可以通过标准单元操作(如沉淀,色谱和过滤)进一步处理含有相溶液的溶液,以进一步纯化目标物并除去任何残留的聚合物。

    • This invention relates to a method of producing protein isolates and concentrates by microfiltration of colostrum, and the production of products fortified with immunoglobulins. The method involves taking a skim colostrum stream, derived from colostrum by the separation of fat and other particulate and cellular material, or by reconstituting skim colostrum powder and water, and microfiltration of that skim colostrum stream to produce a permeate rich in colostral serum proteins and a serum deplete retentate including an enhanced ratio of casein:whey protein. The invention also relates to a method of producing a colostrum powder deplete in whey proteins from colostrum in which an intermediate permeate from the microfiltration, rich in colostral serum proteins, is concentrated and then mixed back with the serum deplete retentate, the mixture optionally being concentrated before drying to produce a colostrum powder deplete in whey proteins. The invention also includes a colostral serum isolate including a protein content of at least 70 %, a colostrum protein concentrate which is serum deplete and includes an enhanced ratio of casein:whey protein and a colostrum powder deplete in whey proteins.
    • 本发明涉及通过初乳微滤制备蛋白质分离物和浓缩物的方法,以及用免疫球蛋白强化的产物的生产。 该方法包括通过分离脂肪和其它颗粒和细胞材料,或通过重构脱脂初乳粉末和水以及该脱脂初乳流的微量过滤来获得源自初乳的脱脂初乳流,以产生富含初级血清蛋白的渗透物,以及 含有酪蛋白:乳清蛋白比例增加的血清消耗滞留物。 本发明还涉及一种从初乳的乳清蛋白中产生初乳粉末的方法,其中来自富含初步血清蛋白的微量过滤的富含初级血清蛋白的中间渗透物被浓缩,然后与血清消耗的滞留物混合,所述混合物任选地被浓缩 在干燥之前产生乳清粉末中的初乳粉末。 本发明还包括初乳血清分离物,其包含至少70%的蛋白质含量,初乳蛋白浓缩物,其是血清消耗的,并且包括酪蛋白:乳清蛋白和在乳清蛋白中消耗的初乳粉末的比例增加。
