磷酸氫鈣 DICALCIUM PHOSPHATE
一、化學(xué)名：磷酸氫鈣
二、分子式：CaHPO4·(0,2)H2O
三、分子量：無水物: 136.06; 二水物：172.09
四、CAS：無水物：7757-93-9；二水物：7789-77-7
五、性狀：白色單斜結(jié)晶粉末，無臭無味，溶于稀鹽酸、硝酸，微溶于水，不溶于乙醇。相對(duì)密度為2.32，在空氣中穩(wěn)定，75℃開始失水成為無水鹽,強(qiáng)熱變成焦磷酸鈣。
六、用途：在食品工業(yè)中作疏松劑、面團(tuán)改良劑、緩沖劑、營(yíng)養(yǎng)增補(bǔ)劑、乳化劑、穩(wěn)定劑等。如作面粉、蛋糕、糕點(diǎn)、烘焙制品的膨松劑，復(fù)配型面包改質(zhì)劑，油炸食品改良劑。亦用于餅干、奶粉、冷飲、冰激凌粉，作為營(yíng)養(yǎng)增補(bǔ)劑或品質(zhì)改良劑。
七、包裝：內(nèi)襯聚乙烯塑料袋，外套復(fù)合塑料編織袋，每袋凈重25kg。
八、貯存與運(yùn)輸：本品應(yīng)貯存在干燥通風(fēng)清潔的庫(kù)房中，裝載運(yùn)輸時(shí)要輕裝輕放，防止包裝破損，防止受潮、受熱，運(yùn)輸過程中防止雨淋受潮，應(yīng)與有毒物品隔離。

1、Chemical Name: Dicalcium Phosphate
2、Molecular Formula : CaHPO4·(0-2)H2O
3、Molecular Weight: Anhydrous: 136.06；Dihydrate: 172.09
4、CAS：Anhydrous :7757-93-9；Dihydrate :7789-77-7
5、Character: It is white monoclinic crystalline powder, tasteless and odorless. It’s soluble in dilute hydrochloric acid, nitric acid but slightly soluble in water, insoluble in ethanol. It’s stable in air. Relative density is 2.32. At 75℃, it starts to lose water and turns to anhydrous salt. With strong heat, it’ll even form Calcium Pyrophosphate.
6、Usage: In food industry, it is used as leavening agent(flour, cake, baking product, etc), modifier( dough, bread, fried food, etc), buffering agent, nutritional supplement(cookies, milk powder, cold drink and ice cream), emulsifier and stabilizing agent.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
