Walnuts With BHT Added To Protect Flavor

Walnuts are the edible seeds of trees from the genus Juglans. They are a good source of healthy fats, protein, and fiber. To preserve their freshness and prevent rancidity, manufacturers may add BHT (butylated hydroxytoluene), a synthetic antioxidant.

BHT is added to foods, especially those containing fats and oils, to prevent them from spoiling or going rancid. This helps maintain the flavor and extends the shelf life of products like cereal, baked goods, and snack mixes. Walnuts with added BHT are often found in breakfast cereals and baking mixes.

BHT is approved by the FDA as a food additive to preserve freshness. The FDA has established conditions for its use. International bodies like JECFA have also evaluated BHT. While generally recognized as safe at permitted levels, some studies have raised questions about its long-term effects, though regulatory bodies consider the current evidence sufficient for its approved uses.
