Sodium Citrate is the sodium salt of citric acid. Like citric acid, it has a sour taste. Like other salts, it also has a salty taste. It is commonly known as sour salt and is mainly used as a food additive, usually for flavor or as a preservative. It gives club soda both its sour and salty flavors. It reduces the acidity of foods, so it allows 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 instantaneously.
Sodium citrates are used as acidity regulators in food and drinks, and also as
emulsifiers
for oils. They enable cheeses to melt without becoming greasy.
Applications
Food
Sodium citrate is chiefly used as a
food additive
, usually for
flavor
or as a
preservative
. Its
E number
is E331. Sodium citrate is employed as a flavoring agent in certain varieties of
club soda
. Sodium citrate is common as an ingredient in
Bratwurst
, and is also used in commercial
ready to drink
beverages and
drink mixes
, contributing a tart flavor. It is found in ice-cream, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine.
Buffer
As a
conjugate base
of a weak acid, citrate can perform as a
buffering agent
or
acidity regulator
, resisting changes in
pH
. Sodium citrate is used to control
acidity
in some substances, such as
gelatin desserts
. It can be found in the mini milk containers used with coffee machines. The compound is the product of
antacids
, such as
Alka-Seltzer
, when they are dissolved in water. A solution of 5 g/100 ml water at 25ºC is 7.5 – 9.0.
Medical uses
In 1914, the
Belgian
doctor
Albert Hustin
and the
Argentine
physician and researcher
Luis Agote
successfully used sodium citrate as an
anticoagulant
in
blood transfusions
, with
Richard Lewisohn
determining its correct concentration in 1915. It continues to be used today in blood collection tubes and for the preservation of
blood
in
blood banks
. The citrate ion
chelates
calcium ions in the blood by forming
calcium citrate
complexes, disrupting the blood clotting mechanism.
In 2003, Ööpik, et al., showed the use of sodium citrate (0.5 grams per kg of body weight) improved running performance over 5 km by 30 seconds.
[3]
Sodium citrate is used to relieve discomfort in urinary tract infections, such as
cystitis
, to reduce the acidosis seen in distal
renal tubular acidosis
, and can also be used as an osmotic
laxative
. It is a major component of the
WHO Oral Rehydration Solution
.
It is used as an antacid, especially prior to anaesthesia, for
caesarian section
procedures to reduce the
risks
associated with the aspiration of gastric contents.
Boiler descaling
Sodium citrate is a particularly effective agent for removal of carbonate scale from boilers without removing them from operation
[4]
and for cleaning automobile radiators.
