How we scored it
Filtrate of a yeast fermentation: all atoms from yeast metabolism of a sugar medium; fermentation-product rule gives 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
Dominant route is fermentation of Schizosaccharomyces yeast on a sugar-based medium followed by filtration. No synthetic route is used.
In plain English
A conditioning, moisture-binding liquid left after fission yeast (Schizosaccharomyces) ferments a sugar-based medium and the yeast is filtered out. It contains the dissolved by-products of that fermentation.
CosIng definition: Schizosaccharomyces Ferment Filtrate is a filtrate of an extract obtained by the fermentation of Schizosaccharomyces
