Is Saccharomyces/Potassium Ferment natural?

Q: Is Saccharomyces/Potassium Ferment natural?

Saccharomyces/Potassium Ferment has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Yeast-fermentation filtrate with potassium ions; potassium is explicitly listed as a natural-origin counter-ion. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

Yes. Yeast-fermentation filtrate with potassium ions; potassium is explicitly listed as a natural-origin counter-ion.

How we scored it

Fermentation product with potassium ion; both are explicitly natural-origin = 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
