PHOSPHATES ON THE TABLE
Phosphate salts enrich all kinds of food with
potassium, phosphorus or calcium. Tricalcium
phosphate, in particular, contains high levels of
calcium and has little effect on the food matrix. When
soluble mineral salts are used, enrichment is combined
with the use of a sequestrant phosphate salt allowing
reactions with ions to be neutralised.
Polyphosphates stabilise fruit drinks and vitamin C in
citrus fruit drinks. Calcium and potassium phosphates
add minerals (calcium, potassium and phosphorus)
to energy drinks. Phosphoric acid is also added as an
acidifying agent in soft drinks like cola.
Tricalcium phosphate improves the flowability
of products such as powdered milk, instant
powders, spices etc. (anti-caking agent).
Phosphoric acid and its derivatives are used in
processing oils and fats used in foods. They are used
to extract de-gum oils during the refining process, to
stabilise fats, to protect against loss of flavour and to
obtain stable emulsions.
