Walnuts With BHT To Preserve Freshness

Walnuts are the edible nuts of trees from the genus *Juglans*. They are native to North America and Eurasia. The nuts are typically harvested, shelled, and sometimes toasted or processed to enhance flavor and shelf life.

Walnuts are often added to baked goods, cereals, trail mixes, and salads for their texture and flavor. BHT (butylated hydroxytoluene) is a synthetic antioxidant sometimes added to walnuts to prevent them from becoming rancid and to preserve their freshness during storage and distribution.

BHT is an FDA-approved food additive used as an antioxidant. The FDA has classified BHT as Generally Recognized As Safe (GRAS) for use in food. Regulatory bodies like JECFA and EFSA have evaluated BHT. While generally considered safe at typical levels, some studies have raised questions about its long-term effects, though evidence is mixed and not conclusive.
