    品名:磷酸氢钙calciumhydrogenphosphate

    中文别名:DCPA粉末;

    英文别名:calcium,hydrogenphosphate;Calciumphosphate;

    分子式:CaHO4P

    分子量:136.057

    精确质量:135.924

    Psa:93.23

    UNII号:L11K75P92J

    外观与性状:白色粉末

    密度:2.306(16℃)

    沸点:158ºC at 760 mmHg

    稳定性:Stable. Incompatible with strong oxidizing agents.

    储存条件:库房通风低温干燥

    安全说明:S26-S36

    危险类别码:R36/37/38

    WGK Germany:3

    海关编码:3103101000

    危险品标志:Xi

    简介:磷酸氢钙是一种化合物,通常以二水合物(其化学式为CaHPO4·2H2O)的形式存在,但可经由加热变成无水的形式。磷酸氢钙几乎不溶于水,在25°C时的溶解度只有0.02g/100mL。

    用途:在食品工业中作疏松剂、面团改良剂、缓冲剂、营养增补剂、稳定剂、乳化剂、稳定剂等。如作面粉、蛋糕、糕点、烘焙制品的膨松剂,复配型面包改质剂,油炸食品改良剂。亦用于饼干、奶粉、冷饮、冰激凌粉,作为营养增补剂或品质改良剂。
