Food safe wood oil penetrates the fibres of porous timber to help reduce moisture absorption and protect wooden kitchenware from bacteria, odours and everyday wear. Common options include food-grade mineral oil, butcher block oil and tung oil. In Australia and New Zealand, always choose a product labelled food-safe or food-grade in line with Food Standards Australia New Zealand (FSANZ) guidelines.
Food preparation combines creativity with practical care. While choosing ingredients and flavours is part of the enjoyment of cooking, maintaining safe and hygienic kitchen surfaces is just as important. One way to do this is by ensuring the materials used in food preparation are properly protected and maintained.
Many commercial kitchens rely heavily on stainless steel and other manmade materials because they can be easily wiped down and sanitised. However, many home kitchens prefer the warmth and natural appearance of materials like wood and stone.
Why wood needs more attention than stone
Natural surfaces such as granite or marble are non-porous, meaning they do not easily absorb liquids or food residue. Wood, however, is naturally porous. It contains microscopic fibres that can absorb moisture, food particles and residue during food preparation. Over time, this can allow bacteria or odours to develop if the wood is not properly sealed and maintained.
That is where food safe wood oil plays an important role. Applying a suitable oil helps seal the wood fibres, reducing moisture absorption while helping protect the surface from damage during everyday kitchen use.
Why is Wood a Potential Hazard in the Kitchen?
Wood remains a very popular material for chopping boards and kitchenware because it is durable, lightweight and visually appealing. Because it is porous, however, small amounts of moisture or food residue can sometimes remain within the fibres even after washing. Over time this can affect the condition of the wood if it is left untreated.
Using a food safe wood oil helps create a protective barrier, reducing the amount of moisture that penetrates the surface while keeping the timber in good condition.
Which wooden kitchen items need treating?
Wooden items in the kitchen are not limited to chopping boards. Common items that benefit from a food safe finish include:
- Chopping boards and serving boards
- Wooden spoons and spatulas
- Salad bowls and fruit bowls
- Bread boards and cheese boards
How to tell if a product is food safe
A food safe finish is a coating made from non-toxic ingredients that are safe for items used in food preparation. The oil must not only be safe, it must also be applied correctly and allowed to cure properly before the item is used again.
In Australia and New Zealand, food safety standards are regulated by Food Standards Australia New Zealand (FSANZ). When selecting an oil or finish, always check the label to confirm it is described as food safe or food grade and suitable for surfaces that come into contact with food. If a product does not clearly state this, it is best reserved for furniture or decorative wood.
Which Oils Are Food Safe?
Several oils can be used as food safe finishes for wooden kitchenware. Here is a quick overview of the most common options:
- Food-grade mineral oil and butcher block oil, widely used, easy to apply, and effective at reducing moisture absorption while maintaining the appearance of the wood.
- Tung oil, a natural drying oil made from the seeds of the tung tree. Once cured, it forms a durable, water-resistant finish.
- Beeswax blends, often combined with oils to create a product that both nourishes and seals the surface in a single application.
Oils vs film sealants: what is the difference?
All oil treatments for wood need to be reapplied from time to time because they are not as hard or durable as chemical-based products such as polyurethane. These varnishes sit on the surface of the wood and are known as film sealants because they create a protective barrier on top. Oils, on the other hand, penetrate the wood and work within it, preventing moisture from soaking in.
Oils are natural and therefore preferable to synthetic finishes from an ecological standpoint, but they are a gentler option and less resistant to scratching and abrasion. The need to reapply them periodically can actually be a benefit, as it means treated items are examined regularly and you can make sure all is well with the wood.
When choosing a product, always select a high-quality oil clearly labelled as food safe and follow the manufacturer's instructions carefully during application.
