    焦磷酸四钠(TSPP) – Food-Grade Phosphates product from Bio Green Foods

    关于此产品

    焦磷酸四钠,分子式为Na4P2O7,CAS号为7722-88-5,欧盟食品添加剂编号为E450(iii)。产品为白色结晶粉末或颗粒,溶于水,水溶液呈碱性,pH约为10。它属于缩合磷酸盐,由两个磷酸单元脱水缩合而成。

    其最显著的食品应用依赖于与钙的反应。在速溶布丁粉中,焦磷酸四钠与牛奶中天然存在的钙反应,形成网络结构,使混合物在室温下数分钟内凝固成凝胶,无需加热蒸煮,这正是免煮布丁得以实现的原因。在肉类、禽类和水产品中,同样的磷酸盐化学以不同方式发挥作用:它提高pH,使其偏离肌肉蛋白的等电点,并解离肌动球蛋白复合物,从而打开蛋白质结构,使其结合更多水分,减少汁液流失和蒸煮损失,并改善质构。它也是铁和铜的有效螯合剂,可保护油脂和色素免受金属催化的氧化,并用作分散剂和缓冲剂。

    用于速溶布丁和甜点、肉类、禽类和水产品加工、再制干酪、水产罐头,以及用作螯合剂。
