ⅠChemical Name: 2-hydroxypropane-1,2,3-tricaboxylate Ca
3
Molecular Formula:
Ca3(C6H5O7)2·4H2O
ⅡMolecular Weight: 324.41
ⅢProperties: White powder,
odourless, slightly deliquescence, difficultly soluble in
water(0.095g/100ml ,25℃),almost insoluble in ethanol, When
heated to 100℃, it may lose crystal water, when heated to
120℃,the crystal will lost water completely.
ⅣQuality standard: FCC-V,USP23
ⅤApplication: Chelant,buffering
agent, coagulant, calcareous intensifying agent,According to
GB1980-94, it can be used in soy and its products. According
to the stiputations of FAO/WHO(1984),its uses and limitation
are low powered concentrated milk, sweet condensed milk, thin
cream, used separately 2g/kg, used together with other
stabilizing agents 3g/kg(no water). Milk powder and cream
powder 5g/kg, melting cheese 40g/kg. As intensified agent of
jam and pectin, tomato tin, cooler and caseinate, its calcium
content in theory is 21.07%. it can be used in flour,
cookie,Japanese fermented soya-bean milk.
ⅥPacking: It is packed with
polyethylene bag as liner and a compound plastic woven bag as
the outer layer. The net weight of each bag is
25kg.
ⅦStorage and transport: Kept in tightly-closed containers, it
should be stored in a dry and ventilative warehouse, kept away
from moisture and hot. Furthermore, it should be separately
from poisonous substances. Handled with care,so as to avoid
damage to bags.
