Canola Corn Oil With TBHQ For Freshness

Canola oil is a vegetable oil made from rapeseed. It is processed to remove certain compounds, then refined, bleached, and deodorized. TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant added to help preserve freshness.

TBHQ is added to oils and fatty foods to prevent oxidation, which can cause spoilage and off-flavors. It helps extend the shelf life of products like snacks, baked goods, and fried foods.

TBHQ is approved by the FDA as a food additive and is generally recognized as safe (GRAS) when used within specified limits. It is also permitted in the EU and other regions. Some studies in animals have raised concerns about potential health effects at very high doses, but regulatory bodies like JECFA and EFSA have evaluated TBHQ and found it safe at typical human consumption levels. Evidence on long-term effects in humans is limited.
