Dimethylpolysiloxane

Dimethylpolysiloxane is a silicone used in very small amounts, often in frying oil to reduce foaming, and it's considered a low-concern additive.

• No known link: It has no histamine and no recognized effect on histamine release or breakdown.

• Limited data: SIGHI, the Swiss list the app follows, leaves it unrated, so the low rating rests on the lack of any known concern.

With fried foods, the food itself and the oil's freshness are usually more worth paying attention to than this additive.
