1.What is Sodium Diacetate?
Sodium diacetate, a 1:1 mixture of sodium acetate and acetic acid, is commonly used as a preservative, flavoring agent and pH adjustment in food. The European food additive number for it is E262(ii). It is sodium acetate with a slight flavor or taste of acetic acid. To be exact, it is the salt of acetic acid and can also be called “dry acetic acid” as composed of free acetic acid in a solid form (39 to 41%).
2.How is Sodium Diacetate Made?
In general, there are two manufacturing processes mentioned from authorities, from the FDA and EFSA, respectively. According to FDA 21CFR184.1754, the synthesis of its technical grade is by reacting sodium carbonate with acetic acid or by reacting anhydrous sodium acetate with acetic acid for the production of special grade. Based on the information from EFSA, the reaction is between sodium hydroxide and a calculated excess of glacial acetic acid to leave sufficient free acid after the production of sodium acetate.
3.Is Sodium Diacetate Safe to Eat?
Yes, its safety when used as a food additive has been approved by the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), Joint FAO/WHO Expert Committee on Food Additives (JECFA), as well as other authorities.
4.What is Sodium Diacetate Used for?
The main purpose of using it in food with its following 3 functions: 1.a preservative to extend food shelf life in bread and meat. 2.a flavoring agent to impart a vinegar taste in savory food. 3.a solid source of free acetic acid to adjust the acidity of food.
