Malic acid has following function:
1.a clean, mellow, smooth, persistent sourness,
2.flavour enhancement and blending abilities,
3.a high solubility rate,
4.lower hygroscopicity than Citric or Tartaric acids,
5.a lower melting point than other acids for easier incorporation into molten confections,
6.and good chelating properties with metal ions.
Dl-malic acid (CAS: 6918-25-4) is a racemic mixture of malic acid, synthesized via fermentation or chemical hydration of fumaric acid. Its molecular formula is C4H6O5. It serves as a versatile intermediate in industrial chemistry.
Store in cool, dry areas away from moisture to prevent caking. Use appropriate PPE to avoid skin irritation; inhalation of dust should be minimized during handling.
