What it is

Red and Green Oak is a type of oak leaf, specifically the leaves of the Quercus rubra (red oak) and Quercus alba (white oak) trees. These leaves are often dried and used for culinary purposes, particularly in pickling and preserving.

Why it's used

Manufacturers add Red and Green Oak leaves to foods like pickles, olives, and relishes to impart a distinct flavor and potentially aid in preservation. They are also found in some deli salads and pre-packaged vegetable products.

Health notes

Red and Green Oak leaves are generally recognized as safe when used as food ingredients. The FDA has not established specific regulations for their use beyond general food safety standards. There is limited scientific research on the specific health effects of consuming these leaves at typical dietary levels. International bodies like JECFA and EFSA have not specifically evaluated these leaves for food additive purposes.
