Natural Flavor

How we reached this

A regulatory category, not an ingredient. 21 CFR 101.22(a)(3) lets 'natural flavor' cover essential oils, oleoresins, distillates and protein hydrolysates derived from plant or animal material — and permits solvents, emulsifiers and preservatives as incidental carriers without separate declaration. Rated mid-scale for that opacity rather than for known harm: the label tells you the source was biological and nothing else.
