DL-Malic Acid
DL-malic acid costs less than the L form and performs the same in applications where the powder is used promptly and moisture pickup is not a problem, such as liquid beverages and immediate-use blends.
Key Specifications
| CAS number | 6915-15-7 |
|---|---|
| E number | E296 |
| Assay | 99-100.5 percent |
| Form | Crystalline powder |
| Hygroscopicity | Higher than L form |
| Mesh | 30 / 60 |
Where the DL form makes sense
DL-malic acid costs less than the L form and performs the same in applications where the powder is used promptly and moisture pickup is not a problem, such as liquid beverages and immediate-use blends.
Handling precaution
It is more hygroscopic than L-malic acid, so bags must be resealed and storage kept dry. Caking in an opened bag is the usual complaint.
Typical Applications
- Beverages — 0.1-0.4 percent where cost is the deciding factor.
- Industrial acidulation — Non-food-grade-sensitive applications within food processing.
Frequently Asked Questions
Can DL replace L 1:1?
Functionally yes at the same weight, though sensory timing differs slightly.
Why is it cheaper?
It is produced by petrochemical synthesis rather than fermentation.
Is it food safe?
Yes, it is an approved food additive E296; the DL designation refers to the isomer mix.
