MAIN FUNCTION AND PURPOSE |
As an acidulant, L-Malic acid is especially suitable for jelly and foodstuff containing Fruit ingredient. It can keep the natural color of juice. Used in healthy drinks, it can resist fatigue and protect liver, kidney and heart. L-Malic acid can enhance pharmaceutical stability and improve pharmaceutical absorption. It can be added into composite amino acid injection, directly participating the metabolic cycle of organism-Krebs cycle. It 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. It is also used in skin disinfector, air depurative and deodorizer. |
