When it comes to maintaining and preserving the beauty of teak cutting boards and butcher blocks, using the right type of oil is essential. Using teak oil on your teak cutting board might seem like a smart way to preserve the natural beauty of wood, but there’s something you should consider before taking this step: is teak oil food safe?
While teak oil is commonly used for protecting and enhancing the appearance of teak furniture, it is not suitable for use on cutting boards.
This is due to its composition and potential risks associated with food contact. In this article, we will explore why teak oil should be avoided on cutting boards and recommend alternative oil types that are safe and effective for teak cutting boards and butcher blocks.
What Is Teak Oil?
True teak oil comes from the teak tree, a tropical hardwood. It is a natural lubricant used for various purposes, including food-safe oil.
However, most commercial teak oil products contain different ingredients. These include pure tung oil, linseed oil, mineral spirits, UV inhibitors, and varnish. The composition of these substances varies from one brand to another. No single product uses the same ingredient ratios or recipe.
Tung and linseed oils are non-toxic if extracted pure and raw. These are highly unlikely, though, especially in the case of cheap oil products.
Meanwhile, mineral spirits usually refer to petroleum naphtha. It is a toxic petroleum derivative used in oil thinners.
Finally, UV inhibitors and varnish finishes can help seal any wooden product. But they have toxic ingredients unless fully cured, which is rarely the case.
Overall, teak oil in many cases contains a tiny amount of pure teak wood oil. It primarily uses natural oils, like linseed and tung, and chemical additives, such as turpentine and varnish.
Is Teak Oil Food-Safe?
Oil is only food-safe if it contains non-toxic ingredients.
Teak oil seems safe around food since it sounds like it comes from an actual teak tree. But as previously mentioned, it is far from the truth. Teak oil is a marketing term that usually refers to various oil blends.
Unfortunately, teak oil includes toxic substances that deem them unsafe for food consumption. Tung oil and linseed oil are among the most common ingredients of teak oil products. They are food-safe as long as they are raw or pure. However, they are mostly treated with chemicals, making them harmful when ingested.
Other components of teak oil include mineral spirits, turpentine, UV inhibitors, and varnish. All of them are toxic chemicals that are not food-safe.
With that said, it is still best to check the product ingredient label. Some brands might have a pure oil composition or a food-safe stamp. But if you do not find these labels anywhere, assume that most teak oil products are not food-safe.
Is Teak Oil Safe for Cutting Boards?
Many homeowners probably read about the benefits of teak oil for wooden products. These include enhancing the wood’s color and grain as well as extending its lifespan.
However, teak oil is toxic for the most part. Thus, it is not a safe finishing option for cutting boards.
Remember that chopping blocks come into contact with food. Using a non-food-safe product, like teak oil, can be a health hazard.
Should You Use Teak Oil on a Teak Butcher Block?
Similar to cutting boards, butcher block countertops also make contact with food. That means most teak oil products, which use chemical additives, are unsafe for sealing a butcher block.
However, some brands might still contain pure tung oil and raw linseed oil. These are food-safe ingredients to use on butcher blocks.
The chances for a product to use 100% natural ingredients are slim, though. In reality, items labeled as tung oil or linseed oil are chemically processed. So if you want to be on the safe side, avoid using teak oil to seal a butcher block or anything that touches food.
What Types of Wood Should You Use Teak Oil On?
By now, you are probably aware that teak oil is not a food-safe product. So, where exactly can you use it?
You can apply teak oil to exterior wooden surfaces, especially teak wood. These include boats, decking, and outdoor furniture made from teak.
You can also use teak oil products on most hardwoods and softwoods. However, note that they perform better on hardwood surfaces. That is because they contain more natural oils that can effectively absorb the properties of teak.
What Are the Benefits of Using Teak Oil?
While teak oil is unsafe for cutting boards or butcher blocks, it still offers several benefits. Using teak oil on the exterior and interior wood surfaces can enhance the grain. It protects them against UV rays and water stains.
Teak oil products also resist cracking or peeling. They can leave a smooth surface for many years to come.
Furthermore, they can restore old or weathered wood to its original state. They can make them appealing again to suit your exterior or interior design.
Finally, teak oils can increase the lifespan of teak and other hardwoods. Just remember to apply these sealing products one to two times a year.
What Types of Oils Are Safe To Use on Your Cutting Board?
Teak oil is out of the choices when it comes to food-safe oil products. However, several natural oils are available for your food-related needs.
Below are some wood oils and finishes that are safe to use on cutting boards and butcher blocks. See our top picks for best oil for teak
Mineral Oil
Also known as liquid paraffin, mineral oil is a non-toxic and non-drying product. It comes from colorless, flavorless, and odorless petroleum.
One of its properties is to prevent water absorption. That makes it popular among kitchen wood items, including spoons, bowls, cutting boards, and butcher blocks.
Note that a few types of mineral oils are unsafe for human consumption. These include machine lubricants in auto or hardware stores. So, it is wise to look for a food-safe label before purchasing one.
Walnut Oil
This is another food-safe oil for your cutting board or other food-related projects. It derives from a nut, making it 100% natural.
Walnut oil completely dries, so it does not go rancid, even when exposed to water. It also smells great in your kitchen.
The only downside is that walnut oils can trigger allergic reactions in people with nut allergies. Be careful when applying this food-safe oil to your kitchen wood products. I wouldn’t use it at all if there was a nut allergy in my family, and would make sure it doesn’t get used if someone with a nut allergy is visiting for dinner.
Coconut Oil (Fractionated)
Coconut oils are rich in saturated fats, making them a popular wood conditioner. They can keep the wooden surface supple and moisturized. Hence, they can resist damage from bacteria or cracks.
Coconut oil products are shelf-stable and will not go rancid. They are ultimately safe for treating cutting boards and other wooden kitchen utensils.
Make sure to look for fractionated coconut oils. That means they have undergone a distillation process.
Beeswax
Beeswax is another popular food-safe oil for your cutting board. This natural wax comes from the hives of honey bees.
It can keep your cutting boards hydrated and shiny. It also offers a waterproof surface to seal in natural wood oils.
However, avoid exposing beeswax-treated woods to heat because they can melt.
Carnauba Wax
This is the last food-grade oil for cutting board maintenance. Carnauba refers to a plant-based wax native to Brazil. It can deliver a glossy finish to wooden surfaces, including chopping boards and butcher block countertops.
Carnauba wax also offers water resistance to prevent warping. It even has a higher melting point than beeswax.
With that said, it is best to keep the wax from high temperatures.
Conclusion
Teak oil is often mistaken for a natural substance from teak trees. The reality is that this product uses a blend of natural oils and chemical additives. These ingredients are toxic and not food-safe. Hence, teak oil is unsuitable for food-related projects, like sealing wooden boards and butcher blocks.
Fortunately, you can still find natural and food-safe oils for your wooden kitchen utensils. Consider mineral oils, walnut oils, and beeswax, among other food-grade products.
