Functions and usage:
It is an important four-carbon atoms chiral pool. It is mainly used
in many fields including chiral pharmaceuticals, chiral additives
and chiral auxiliaries. It is used as chiral pool of chiral
synthesis in pharmaceutical and food industries. As an optically
active organic acid, it is insubstitutable in asymmetry synthesis
of some chiral compounds.
DL-Malic acid can be used as an acidulant in cool drinks (including
lactobacillus drinks, milk drinks, carbonated drinks, cola), frozen
foods (including sherbet and ice cream), processed foods (including
wine and mayonnaise). DL-Malic acid is used as color-keeper and
antiseptic of juice. DL-Malic acid is also used as emulsion
stabilizer of egg yolk. DL-Malic acid also can be used as
pharmaceutical intermediate, cosmetic, rinse, metal cleaner,
buffering agent, retarder in textile industry, fluorescent
whitening agent of polyester fibre.
L-Malic acid can be added into composite amino acid injection,
directly participating the metabolic cycle of organism-Krebs cycle.
L-Malic acid can reduce the metabolic loss of amino acid and can
compensate hypohepatia, cure uremia and hypertension, and weaken
the damage of anticancer drug to normoblasts. L-Malic acid is also
used in skin disinfector, air depurative and deodorizer.
