Subdivision 2 – Calculations

3 Calculation of energy

The energy content of infant formula product, expressed in kilojoules (kJ), must be calculated using –

(a) only the energy value contributions of the fat, protein and carbohydrate ingredients of the infant formula product; and
(b) the relevant energy factors set out in Standard 1.2.8.

4 Calculation of protein

The prescribed formula for the calculation of the protein content of infant formula product for the purposes of this Standard is –

Note: Formula

Note: For milk proteins and their partial protein hydrolysates –

Note: Protein content = nitrogen content x 6.38; or

Note: In any other case –

Note: Protein content = nitrogen content x 6.25.

5 Calculation of potential renal solute load

The prescribed formula for the calculation of the potential renal solute load for the purposes of this Standard is –

Note: Formula

Note: Potential renal solute load in mOsm/100 kJ = [Na (mg/100 kJ) /23] + [Cl (mg/100 kJ) /35]

Note: + [K (mg/100 kJ) /39] + [P avail (mg/100 kJ)/ 31] + [N (mg/100 kJ) /28)].

Note: In this formula

Note: P avail = P of milk-based formula + 2/3 of P of soy-based formulas.
