Yes, wooden spoons can release tannins into food, especially when they are new or have not been properly seasoned. Tannins are natural compounds found in wood that can impart a slightly bitter taste to food. However, with proper seasoning and use, the amount of tannins released into food can be minimized. It is also important to note that the type of wood used for the spoon can impact the release of tannins, with hardwoods like maple and cherry being less likely to release tannins compared to softer woods like pine. **

Plants that are commonly used to extract tannins for tanning include oak trees, chestnut trees, and quebracho trees. These plants have high concentrations of tannins in their bark, leaves, or fruits, which are used in the tanning process to convert animal hides into leather. The tannins in these plants help to bind and stabilize the collagen fibers in the hides, making them more durable and resistant to decay. **
