Anionic-classed food ingredients — certified FD&C color additives (Red No. 4, Red No. 40) and taurine — grouped by molecular charge; supplied with FCC and Kosher documentation on request.
La línea aniónica de RawSource para alimentos y bebidas es pequeña y refleja cómo el catálogo clasifica los productos por carga molecular y no por uso. The three products grouped here carry anionic or zwitterionic groups, but their food function is not emulsification: two are certified FD&C color additives (Red No. 4 and Red No. 40) and one is taurine, an amino-sulfonic acid supplied as a functional ingredient.
For the certified colors, the trade-off is precision against regulatory exposure. Synthetic certified dyes deliver an exact, batch-reproducible shade with strong stability in low-pH beverages and confectionery, where natural colorants vary lot to lot. Against that, color additives are subject to FDA batch certification and listing, and several face tightening state-level restrictions. FD&C Red No. 4 in particular is not broadly permitted for general food use. Confirm current FDA color-additive status for your application before specifying.
Taurine is supplied as a functional ingredient, commonly used in beverage formulation. Classic anionic food emulsifiers such as stearoyl lactylates or DATEM are not part of this anionic-classed set. For oil-in-water emulsification, the nonionic polysorbate and sorbitan-ester line is the working set.
