    • The present invention generally relates to compositions comprising the proteose peptone fraction (PPf). In particular, the present invention relates to a method for the production of an extract comprising a demineralised protein fraction depleted in β-lactoglobulin and enriched in the PPf and to uses of these extracts, e.g. in a food product, a food supplement, a nutritional, a pharmaceutical and/or a cosmetic composition, for example as emulsifier or as foaming agent.The PPf fraction of the present invention may be obtained by adjustment of the pH of an aqueous native protein dispersion to about 5.6 to 8.4, or to about 3.5 to 5.0, heating the aqueous native protein dispersion to about 70-95 °C for about 10 seconds to 60 minutes, removing at least a part of the formed solid large molecular weight aggregates with a diameter of at least 100nm from the aqueous protein dispersion after heating and collecting the remaining liquid fraction of the dispersion.
    • 本发明一般涉及包含蛋白胨部分(PPf)的组合物。 特别地,本发明涉及一种生产提取物的方法,所述提取物包含去除了β-乳球蛋白的去矿物质蛋白质级分并且富含PPf,以及这些提取物的使用,例如, 食品,食品添加剂,营养剂,药物和/或化妆品组合物,例如作为乳化剂或发泡剂。本发明的PPf级分可以通过调节水性天然蛋白质的pH来获得 分散至约5.6至8.4或至约3.5至5.0,将天然蛋白水解物分散体加热至约70-95℃约10秒至60分钟,除去至少一部分形成的固体大分子量聚集体 直径在加热后从蛋白质水分散体中至少100nm,并收集分散体的剩余液体部分。
