Why Citrus Fruits Are Waxed
Before answering the question, it's helpful to understand why produce is waxed at all. All citrus fruits, including oranges, naturally produce a layer of wax to protect their skin from moisture loss and external damage while on the tree. However, when fruit is harvested, cleaned, and processed for commercial distribution, this natural protective layer is often washed away or damaged.
To compensate for this, growers and distributors apply a new, thin coat of edible wax to the fruit. This process serves several key functions:
- Preserves Freshness: It seals in moisture, preventing the fruit from drying out and shriveling, which extends its shelf life.
- Protects from Damage: The wax acts as a barrier against bruising and other physical damage during transport and handling.
- Prevents Spoilage: It helps protect against decay caused by mold and fungi, a significant concern for organic fruit which is not treated with synthetic fungicides,.
- Enhances Appearance: A shiny, polished look makes the fruit more visually appealing to consumers.
The Difference: Organic vs. Conventional Wax
The primary distinction between organic and conventional oranges lies not in whether they are waxed, but in the source and content of the wax itself. Under regulations set by bodies like the USDA, any coatings on certified organic produce must come from natural, non-synthetic sources.
Approved Organic Waxes
Organic produce is coated with natural substances that meet strict organic standards. Common examples include,:
- Carnauba Wax: Derived from the leaves of the Brazilian palm tree Copernicia cerifera, this wax is widely used and approved for organic applications.
- Beeswax: This natural wax is sourced from bees and is another common coating for organic produce.
- Shellac: A resin secreted by the female lac bug, shellac is also permitted as a food-grade coating for organic fruits.
Conventional Waxes
Conventional (non-organic) produce waxes are less regulated regarding their composition. They can include petroleum-derived ingredients such as paraffin and polyethylene waxes. Furthermore, fungicides and other chemical preservatives, which are prohibited on organic produce, are often added to conventional waxes to prevent mold and extend shelf life.
Comparison of Waxing Practices
| Feature | Organic Waxing | Conventional Waxing |
|---|---|---|
| Wax Source | Natural (e.g., carnauba, beeswax, shellac) | Synthetic (e.g., paraffin) or natural |
| Added Chemicals | No synthetic fungicides or preservatives permitted | May contain synthetic fungicides and preservatives |
| Vegan-Friendly | Varies; beeswax and shellac are animal-derived | Often not vegan-friendly due to varied ingredients |
| Biodegradability | Generally biodegradable | May be less environmentally friendly |
| Primary Purpose | Replenish natural protection lost in washing | Replenish natural protection and maximize shelf life |
How to Identify and Remove Wax from Oranges
If you prefer to remove any coating, whether for a recipe calling for zest or for personal preference, there are simple methods. To identify if an orange is waxed, look for an unusually high, uniform shine. You can also feel the surface, as waxed fruit may feel slightly sticky or slick.
To remove the wax coating:
- The Hot Water Scrub: Run the orange under a hot, running tap while scrubbing gently with a vegetable brush. For a deeper clean, pour water from a recently boiled kettle over the fruit.
- The Baking Soda Soak: For a more thorough cleaning, dissolve a tablespoon of baking soda in a bowl of warm water. Submerge the orange and scrub with your hands or a soft brush before rinsing thoroughly under cool water.
- The Vinegar Solution: Mix one part white vinegar with three parts water. Soak the fruit for a few minutes, then scrub and rinse well. This acidic solution can help dissolve the wax layer.
After removing the wax, remember that the fruit will have a shorter shelf life, so it's best to use it soon.
Are Waxes on Organic Oranges Safe?
Yes, the waxes used on organic oranges are considered safe for consumption,. They are food-grade and approved by regulatory agencies like the FDA. The coatings are applied in minimal, microscopic amounts, and because they are natural and biodegradable, they pose little to no health risk. For those concerned about animal products, however, it's worth noting that beeswax and shellac are animal-derived. Some vendors, particularly at farmers' markets, may sell unwaxed organic fruit, but checking with the producer is the best way to confirm the use of wax.
The Rise of Unwaxed Organic Alternatives
Some organic growers and distributors recognize consumer preference for untreated fruit. Companies like Organically Grown Company (OGC) mentioned that some of their organic citrus growers choose dry brushing over waxing. Dry brushing helps remove dirt and adds a slight shine by releasing the fruit's natural oils, but it leaves no additional coating. This practice results in fruit that may have a slightly duller finish and a shorter shelf life, but it ensures that the consumer is getting a truly 'naked' orange. Such produce is more common in farmers' markets or specialized retail outlets. For more information on the specific practices of growers, one can often find details on company websites or ask a produce manager..
Conclusion
In summary, the answer to "Do organic oranges have wax on them?" is a definitive yes, but with the important caveat that the wax is natural and organic-approved. This post-harvest treatment is a necessary step to protect the fruit after its own natural coating is removed during cleaning. The key difference from conventional oranges lies in the source of the wax—natural versus synthetic—and the absence of chemical fungicides. While the waxes are safe, consumers who prefer an unwaxed product can either wash the fruit thoroughly or seek out growers who use alternative methods like dry brushing. Making an informed choice at the grocery store empowers consumers to select produce that aligns with their personal health and ethical considerations, all while ensuring the fruit arrives fresh and in good condition.
