How we scored it
Mg2+ (mineral ion, natural) + citrate C6H5O7 (fermentation) = 1.0
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Made by neutralising fermentation-derived citric acid with a magnesium base. No significant alternative route exists.
