The popularity of food-safe wood finishes has drastically increased in recent years as we have become more conscious about the high volumes of toxins surrounding us. We need to be very careful about what we’re ingesting. That’s why using food-safe wood finishes on wooden objects that come into contact with our food and our mouths are very important.
There are a variety of different food-safe finish options to choose from. Along with this, there’s a vast amount of factors to consider when choosing the right food safe wood finish for you.
Considerations To Keep In Mind
Many finishes become safe to use on objects if the finish is applied correctly and has enough time to cure it completely. Nonetheless, there are some things you need to pay close attention to when applying these finishes to wooden objects.
Oils That Can Spoil Should Be Avoided
Many recommendations suggest using vegetable oils such a sunflower and olive oil to coat wooden utensils. This is a finish that should be avoided as these types of oils are made from fat extracted from vegetables.
Due to this, these oils are going to spoil over time, as there is shelf life. These oils don’t have the necessary materials to be long-lasting. Ultimately, using any of these oils will result in it not remaining on the particular surface, and it’s likely to produce an off-taste when the utensils are in use.
A common misconception is that drying time is the same as curing time. It’s not. Your finish isn’t cured once it’s dried.
Pre-made wood finishes often have the drying time listed on the label. It’s important to note that this is the recommended time regarding how long you should wait before applying any additional coats. This is the manufacturer’s recommendation, and it’s in your best interest to follow it. The layers underneath the top layer may not be dry even if the top layer feels dry to the touch.
These pre-made products also list each product’s curing time. This is the suggested time that you should wait before using the item that’s been finished. Once an item has been cured, the surface and the deepest penetration spots are dry.
Levels Of Toxicity
The application process is the first level of concern when involving toxicity. It would be best to have adequate ventilation in the workspace to apply the finish to the object. Moreover, it would also be extremely beneficial to purchase some breathing protection.
A shared thought among many woodworkers is that dust masks can be labeled as sufficient protection. This is true if you want to prevent wood particles from going into your nose and lungs. However, these dust masks can’t protect you against the wood finishes’ harmful chemical vapors. It’s highly suggested that you purchase a specially designed respirator to filter out these toxic chemicals from the air you breathe in.
Other than the toxicity present in the air, another concern is the toxicity levels on the treated items used for toys and food. The least toxic finishes that you can use are boiled linseed oil and tung oil. The next best option after these finishes is Shellacs, along with water-based finishes. Lastly, the most toxic finishes that can be used are finishes like lacquers.
No matter what type of finish, most of these products are safe to be used on wooden items. However, this safety is dependent on whether you apply the finish precisely as stated by the manufacturer and that you wait until the item is entirely cured before you start using it.
How Does Heat Affect The Finish?
There are two concerns that you need to keep in mind. The first concern is the recommended temperature range the finish should be stored at. Chemicals can be negatively affected if the product is stored at a temperature too low. The result of this occurring is that the chemicals break down. This is the same for chemicals that are kept at a higher temperature. This may result in the product combusting. Following these temperature guidelines also helps to yield the best results from the finish.
Another concern is the temperature that the utensils are going to be used. Items that are used for cooking, such as spatulas and spoons, are exposed to scorching surfaces. It would be best to make sure that the particular finish you choose can withstand these intense temperatures without melting or breaking down as you use them for cooking. You can easily verify this information by reading the label provided on the product.
Can The Finish Hold Up?
Some cases require you to apply a finish that creates a hard surface. However, there are other cases where this should be avoided altogether. Finishing a cutting board is one of those cases. A wooden object that will be hammered at or cut on is likely to require a softer finish that features a limited flaking amount.
This is to prevent the flakes of the finish clinging to your food. The shape of the item plays a role in deciding the durability of the finish. Utensils and boards with sharp edges are likely to wear out sooner than boards and utensils with a rounded or beveled edge.
Items that have indentations or grooves can also cause problems. This is because these imperfections can become a collection point for grease or bacteria to build up. Softer finishes are more likely to become susceptible to these collection points occurring.
This is due to softer finishes being more permeable than harder coatings. The unwanted build-up is more than likely going to penetrate the surface. In this case, you will have to strip down the finish and re-apply it, as it’s impossible to clean off this build-up once the penetration occurs.

Finishes You Should Use With Caution

I personally do not use chemicals or unnatural substances like wood stains, especially in products like cutting boards, etc. that pieces of the stain can eventually reach my stomach.
Is polyurethane food safe?
Polyurethane used many years ago is different from the food-safe polyurethane available today. Polyurethane reduces the drying time required for a complete cure by using metallic driers in the formula. Before this, polyurethane contained lead to reduce the drying time. However, it’s been banned for several years.
A commonly asked question: “Is polyurethane food safe?” There isn’t any evidence to prove otherwise. Nonetheless, it’s essential to keep in mind that all finishes can be unsafe if not cured correctly before use. For that reason, application guidelines need to be followed precisely to ensure that the polyurethane finish remains food-safe and provides a protective covering for wooden kitchen utensils and cookware.
Is lacquer food safe?
Applying a lacquer finish requires the longest curing time when compared to other types of finishes. Lacquer coating is food-safe when the layer has fully matured. This finish doesn’t penetrate the wood grain, as it can be classified as a food-safe sealant silicone that sits on top of the wooden surface.
This is the preferred finish for wooden items that aren’t going to be roughed up. Such things can include serving trays. Applying this finish to a cutting board isn’t recommended as it tends to flake.
Can you use wood stain on a cutting board?
Yes, you can use Mineral Oil, Beeswax, Walnut Oil, and Fractionated Coconut Oil. If you are using regular wood stain, the chemicals come in contact with food, and this can cause health problems.
Can you use Vegetable Oils as a wood stain? Can You Treat Wood With Cooking Oils?
Although there are a few vegetable oils mentioned above as possible wood finishes, most vegetable oils should be used cautiously or avoided altogether. There are a variety of reasons why vegetable oils should be avoided.
One reason is that these products tend to thicken on utensils’ surface and create a cloudy appearance. This results in the wood surface having an off-feel. Another reason is that applying vegetable oils can discolor your wooden items. Finally, these oils can become rancid and cause your wooden utensils to smell bad.
How do you seal a wooden cutting board?
1. Sand the cutting board with 320 grit sandpaper.

A vast amount of finishes can be used to add a food-safe protective layer to your wooden items. Each one has its own benefits, and some finishes can be used in conjunction with one another to provide both of the products’ benefits while combating the adverse effects.
