How we scored it
High-polymeric carbohydrate isolated from corn kernels; wet-milling separation, no chemical modification; botanical starch = 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
Extracted by wet-milling the peeled seeds of corn (maize) to isolate native starch granules. No petrochemical alternative route exists for this unmodified starch.
In plain English
A fine powder starch from corn kernels, used to absorb moisture and prevent caking. It's separated from corn by simple milling, with no chemical modification.
CosIng definition: Zea Mays Starch is a high-polymeric carbohydrate material usually derived from the peeled seeds of the Corn, Zea mays L., Gramineae
