NAME: Ferric orthophosphate<br />

CATEGORY: Nutritive additive<br />

FOOD USE: Breads/ Cereals/ Cornmeal/ Dietary supplements/ Dietetic foods/ Egg products/ Farina/ Flour/<br />

Formulated liquid diets/ Fruit-flavoured drinks and bases/ Heat-and-serve dinners/ Infant cereals/ Infant<br />

formulae/ Meal replacements/ Rice/ Pasta/ Peanut spreads/ Simulated meat and poultry products<br />

SYNONYMS: Iron phoshate/ Iron (III) phosphate/ Ferric phosphate/ Ferric (III) phosphate/ Ferriphosphate/ CAS<br />

10045-86-0 anhydrous, 14940-41-1 tetrahydrate/ EINECS 233-149-7 anhydrous, 239-018-0 tetrahydrate<br />

FORMULA: FePO4 · x H2O, x = 1–4<br />

MOLECULAR MASS: 150.82 (anhydrous)<br />

PROPERTIES: Tasteless; bioavailability of pure compound is poor<br />

APPEARANCE: Dihydrate is white, greyish-white, or light pink crystals or amorphous powder<br />

MELTING POINT (°C): Loses water above 140<br />

DENSITY: 2.87 (dihydrate)<br />

SOLUBILITY % AT VARIOUS TEMPERATURE/pH COMBINATIONS:<br />

in water: Practically insoluble in water<br />

FUNCTION IN FOODS: Enrichment, fortification, or restoration<br />

ALTERNATIVES: Ferric choline citrate/ Ferric pyrophosphate/ Ferrous fumarate/ Ferrous gluconate/ Ferrous lactate/<br />

Ferrous sulphate/ Reduced elemental iron/ Sodium iron pyrophosphate<br />

TECHNOLOGY OF USE IN FOODS: Used when whiteness and inertness are priorities. Phytic acid, fibres, phosphates, polyphenolics, some<br />

proteins, and organic acids can adversely affect iron absorption, whereas other compounds such as<br />

ascorbic acid and some amino acids enhance the absorption of this mineral<br />

FOOD SAFETY ISSUES: When heated to decomposition, toxic fumes of POx are emitted
