Doubtful — depends on source
E570 (Stearic acid / fatty acids) is a fatty acid that can be animal- or plant-derived — so it is treated as doubtful (mushbooh) unless the source is known.
Stearic acid is a fatty acid used as an emulsifier, anti-caking agent and glazing agent in foods, and widely in supplements, tablets and cosmetics. It can be obtained from vegetable oils or from animal fats.
Obtained by splitting fats and oils into their fatty acids. The feedstock can be vegetable (e.g. palm) or animal (tallow) — the label rarely says which.
Stearic acid is doubtful because it can be plant- or animal-derived, and the source is usually unstated. Plant-derived stearic acid is halal; animal-fat stearic acid is only permissible if from a halal animal. Verify before assuming — much commercial stearic acid is palm-derived, but this should be confirmed.
It may be found in — this does not mean every product below contains it.
