    磷酸氢二钠(DSP) – Food-Grade Phosphates product from Bio Green Foods

    关于此产品

    磷酸氢二钠的分子式为 Na2HPO4,CAS 号 7558-79-4,欧盟食品添加剂编号 E339(ii)。可供应无水物或水合物,为白色结晶粉末,极易溶于水,水溶液呈弱碱性,pH 约为 9。

    它的两项作用看似互不相关,实则机理相同。作为缓冲剂,它把 pH 稳定在中性偏碱一侧,使乳蛋白在灭菌过程中不致受热凝固,并防止淡炼乳凝胶化。作为再制干酪中的乳化盐,它通过螯合钙发挥作用。天然干酪中,酪蛋白被钙桥锁定在网络结构中,因此受热时干酪会分离为拉丝状蛋白和游离油脂。磷酸盐结合这部分钙并将其从网络中脱除,使酪蛋白得以作为乳化剂,把脂肪和水保持在平滑、稳定、融化均匀的整体中。这一机理正是整个再制干酪品类的基础。它还用于多种产品的 pH 调节,并用作螯合剂。

    用于再制干酪和干酪酱、淡炼乳和甜炼乳、速溶布丁、谷物制品、肉类盐水和饮料。

    Bio Green Foods 按含量、pH 值、干燥失重、水不溶物、氟化物和重金属等指标供应符合规格的食品级磷酸氢二钠。
