Wood stains are toxic during the application and drying process. Therefore, they only become food-safe after curing. Yet, most wood stains aren’t tested for food safety but comply with FDA’s food safety requirements.
The key to finding a food-safe wood stain is identifying the oil type you plan to use. For example, you can use lighter oils such as tung oil and linseed on raw wood. They don’t run the risk of discoloring the surface once they dry.

With Hope’s tung oil, you can protect your wood projects from water, oil, alcohol, and daily wear. Unfortunately, while it’s more durable than shellac products and promises longer-lasting protection, it takes longer to dry.

Buyer’s Guide: How To Choose The Best Food Safe Wood Stain And Sealer
With all these choices, choosing the best food-safe wood stain and sealer can be a hard nut to crack. Fortunately, food-safe finishes don’t feature a wide range of variations. Here is a guide that’ll help you settle for the best option for your project;
Penetrating Oil Vs. Surface Sealer
Penetrating oils are your best bet if you want a finish that’ll soak into the wood and offer protection from the inside. While they’re easier to apply, they offer less protection than surface sealer finishes. However, they deliver a more natural look and feel.
On the other hand, surface sealers, also known as film finishes, remain on the surface and act as a barrier. Moreover, it leaves a layer that you can recoat for additional protection. Also, as you’d expect, it’s more protective than penetrating oils.
However, they can be tricky to apply, especially without the right woodworking experience. A good rule of thumb is to use surface sealers on projects subject to more physical abuse, moisture, wear, and tear, or harsh cleaning agents.
Penetrating finishes will work fine for decorative pieces and projects that don’t require additional protection, such as toys and frames. They accentuate the wood grain and deliver a beautiful satin finish.

Drying vs. Non-Drying Oil finishes
These two categories fall under penetrating oils. A drying oil typically undergoes polymerization- a process where it cures and turns solid- when it comes in contact with oxygen.
As a result, the curing process begins immediately after applying the finish onto a wood surface. Common drying oils include tung oil, walnut oil, and linseed oil.
In contrast, a non-drying oil remains wet indefinitely. Subsequently, this oil type is more of a treatment and not a true finish. Since it doesn’t cure, it can wash off over time. . Common non-drying oils include mineral oil, coconut oil, and vegetable oil.
Pick A Trusted Brand.
Regardless of the product’s nature, you’ll want a food-safe finish if your project comes into direct food contact. As a result, settle for reputable brands with a history of manufacturing food-safe products.
Finally, before using a wood stain, go through the instructions and properties to ensure it is food grade.
