Canola With TBHQ For Freshness

Canola oil is a vegetable oil made from the seeds of the canola plant. The seeds are crushed to extract the oil, which is then refined and purified. TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant that is sometimes added to canola oil to prevent it from going rancid and maintain its freshness.

Manufacturers add TBHQ to oils and fatty foods to prevent oxidation, which can cause spoilage and off-flavors. It helps extend the shelf life of products like baked goods, snack foods, and fried items. TBHQ is often found in processed foods that contain fats or oils.

In the U.S., TBHQ is approved by the FDA as a food additive and is generally recognized as safe (GRAS) when used within specified limits. Studies have looked into its effects, but the evidence on health impacts at typical consumption levels is mixed. International bodies like JECFA have evaluated TBHQ, but no specific numeric limits are provided here. Some research has raised questions about potential health effects, but regulatory bodies consider it safe at permitted levels.
