焦磷酸二氢二钠 SAPP
化学式： Na2H2P2O7
分子量： 221.94
CAS No.: 7758-16-9
EINECS No.: 231-835-0
H.S CODE: 28353990
性状
白色粉末或白色颗粒，相对密度1.86，溶于水,不溶于乙醇，水溶液与稀无机酸加热则水解成磷酸，有吸湿性，吸水后形成六个结晶水合物，加热至220℃以上时分解生成偏磷酸钠。
用途
用作发酵剂，用于烘烤食品，控制发酵速度；用于方便面，缩小成品复水时间，不粘不烂；用于饼干糕点，缩短发酵时间，降低产品破损率，疏松空隙整齐，可延长贮存期。
包装及贮运
25Kg, 50Kg，1000kg内塑外编袋装。贮于通风、干燥、清洁处，防潮湿。
执行标准：GB25567-2010
