USE: As food sourness agent,fumaric acid plays an important role in bacteriostasis and antisepsis ,which
is used as regulator of acidity,acidulant,temperature resistance oxidation assistant ,bloat accelerant and
flavor fumaric acid is the intermediate for fine chemicals like medicament and optics bleacher and so forth
In medicament industry ,it is used to produce the alexipharmic sodium dimercaptosuccinate and the ferrous
fumarate that cures microcyte anemia.Fumaric acid is also used to produce unsaturated polyester resin and
also is the main raw material of producing L-aspartic acid.
Package:25KG woven bag with plastic liner,it also can be determined according to customer’s requirement.
Storage:keeping in a well-closed ,light-resistant,dry and cool place. |
