It is commonly known as sour salt, buffer salt or trisodium citrate and is mainly used for flavouring food and drinks or as a preservative. A useful quality of Sodium Citrate is that it reduces the acidity of foods and liquid solutions, so it allows spherification and reverse spherification with strongly acidic ingredients. Sodium Citrate is also used as an antioxidant in food as well as a sequestrant. It dissolves easily and acts instantly. A highly soluble powder. Suitable for Vegans, Vegetarians, Non-GMO, Gluten Free, Non-Irradiated, Kosher Friendly, Halal Friendly.


  • Rapidly reduces the acidity of food and liquids

Adjusting pH with Sodium Citrate:

To adjust the pH of acidic liquids, add Sodium Citrate concerning the percentages given.

To the change the pH of a liquid to a neutral pH of 5 add Sodium Citrate to the liquid as follows:

Liquid with pH 2 – Add 0.3% Sodium Citrate = pH 5

Liquid with pH 2.5 – Add 0.09% Sodium Citrate = pH 5

Liquid with pH 3 – Add 0.03% Sodium Citrate= pH 5

Liquid with pH 3.5 – Add 0.01% Sodium Citrate= pH 5
