Soybean Oil With TBHQ Added To Protect Freshness

Soybean oil is a vegetable oil extracted from the seeds of the soybean plant. It is one of the most widely used oils in the United States. To prevent it from going rancid and to extend its shelf life, manufacturers often add a synthetic antioxidant called TBHQ (tertiary butylhydroquinone).

TBHQ is added to soybean oil to act as a preservative, protecting it from oxidation and spoilage. This helps maintain the oil's freshness and flavor. It is commonly found in processed foods that contain fats and oils, such as salad dressings, mayonnaise, and imitation bacon bits.

TBHQ is approved by the FDA as a food additive to protect foods from spoilage. The FDA has affirmed that TBHQ is Generally Recognized As Safe (GRAS) when used according to regulations. JECFA and EFSA have evaluated TBHQ and established acceptable daily intake levels. While generally considered safe at typical consumption levels, some studies have raised questions about potential health effects at very high doses, though these are not typically encountered through normal food consumption.
