Product Physical Properties
Characteristics of dl-Malic
Acid
Malic Acid that is abundantly contained
in fresh fruits such as apple and vegetables, is an acidulant necessary
for man's carbohydrate metabolism. Compared with citric acid
which is also an acidulant, Malic Acid has stronger acidity
and makes you save about 20% in usage. The taste is extraordinarily
smooth and the acidity lasts much longer so that it gives greater
pleasure to man's appetite.
In particular, Malic Acid is indispensably
required for manufacturing diet food/drinks using artificial saccharoids such
as aspartame. It is also widely used as an acidulant for hard food
like candies because of its low melting point. The handling
and storage of Malic Acid is easy due to its excellent stablity
and it is possible to keep it for long as it has no hygroscopic
nature. As shown in the graphs on the below, Malic Acid certainly
has a better taste than citric acid.
