    磷酸氢二钾(DKP)

    磷酸氢二钾(DKP) – Food-Grade Phosphates product from Bio Green Foods

    关于此产品

    磷酸氢二钾,又称二钾磷酸盐或DKP,分子式为K2HPO4,CAS号为7758-11-4,欧盟食品添加剂编号为E340(ii)。产品为白色潮解性颗粒或粉末,极易溶于水,水溶液呈弱碱性,pH约为9。

    其价值在于缓冲作用。缓冲剂可在加入酸时抵抗pH变化,而DKP使体系保持在中性偏碱一侧。最典型的例子是植脂末。咖啡呈酸性,植脂末与之接触时,局部pH可能降至其蛋白质的等电点,此时蛋白质失去电荷,不再相互排斥,絮凝成肉眼可见的颗粒,即所谓的羽化(feathering)缺陷。在植脂末中加入DKP可提高并缓冲其pH,使其与咖啡混合时始终不会达到该点。同样的缓冲作用用于稳定乳制品中的蛋白质,并在发酵中保持pH恒定,同时提供钾和磷作为营养元素。它提供的是钾而非钠,适合低钠配方。

    用于植脂末和奶精、再制干酪、炼乳和乳粉、等渗饮料和蛋白饮料、发酵培养基,以及作为营养盐使用。

    Bio Green Foods 按含量、pH、干燥失重、氯化物、氟化物、砷和重金属的规格供应食品级DKP。
