Disodium malate

Disodium malate (E350i, CAS 676-46-0) is the disodium salt of malic acid, supplied as a liquid solution. It is also referred to as sodium malate or apple sodium in trade contexts. The compound carries EC number 211-627-6 and the molecular formula C4H6O5.2Na.

In food and beverage formulations, disodium malate functions as a buffering agent and acidulant, moderating pH in sauces, dressings, and processed foods without introducing sharp acidity. In pharmaceutical applications, it stabilises the pH of oral and topical preparations, improving shelf stability and active ingredient compatibility.

Disodium malate is available in food-grade and pharmaceutical-grade liquid form, compliant with E350i specifications under EU food additive regulations and alignable with FCC and Ph.Eur. standards where applicable.
