Acidity Regulator E296 Food Additive DL-malic acid vs Malic Acid
DL-malic acid and malic acid are closely related, but with a key difference in their structure:
Malic Acid: This is a general term that can refer to both L-malic acid and D-malic acid, which are mirror images of each other at the molecular level (stereoisomers).
L-malic acid powder is the naturally occurring form found in fruits and vegetables like apples, grapes, and cherries.
D-malic acid is much less common in nature and is typically produced synthetically.
DL-malic Acid: This is a specific type of malic acid that is a 1:1 mixture of L-malic acid and D-malic acid. It's produced synthetically through a process called racemic mixture.
Here's a table summarizing the key points:
| Feature | L-Malic Acid | D-Malic Acid | DL-Malic Acid |
| Source | Natural | Synthetic (rarely natural) | Synthetic |
| Common in nature | Yes | No | No (mixture) |
| Commercially available | Yes (fermentation) | Yes | Yes |
In essence:
Malic acid refers to both L-malic acid and D-malic acid.
DL-malic acid is a specific type of malic acid that combines both L and D forms.
Applications:
Both L-malic acid and DL-malic acid are used as food additives to add tartness to candies, beverages, and some savory foods.
DL-malic acid is more commonly used in supplements due to its lower production cost.
