Why citrus fruit is wrapped in paper — and why it matters

If you have ever bought oranges at a market in Valencia — or from any fruit shop that takes its stock seriously — you will have noticed that each piece comes wrapped in thin, almost translucent paper. It is not decoration. It is a technique with over a century of use, and the reasons are practical.

What the paper does

The paper around citrus fruit serves several purposes at once, none of them aesthetic.

Physical protection. Citrus fruit has a tough skin, but it is not indestructible. A knock during transport can rupture the essential oil cells in the rind, and that spot becomes the entry point for mould. The paper cushions impacts and stops the fruit rubbing against each other inside the crate.

Moisture control. The tissue paper absorbs the surface condensation that forms when the fruit moves from a cold environment to a warmer one. That thin layer of water is precisely what mould spores need to germinate. The paper absorbs it before it becomes a problem.

Ethylene barrier. Citrus fruit produces ethylene, a gas that speeds ripening. When one piece starts to deteriorate, it releases more ethylene, which affects its neighbours. Individual paper wrapping slows that transmission: if one orange goes bad, the damage does not spread as quickly to the rest of the crate.

Odour isolation. Citrus fruit absorbs odours easily. In a warehouse or during a long journey, the paper acts as a barrier between the fruit and any external smell — wood, damp cardboard, other goods.

Not any paper will do

The paper traditionally used is sulphite tissue — thin and slightly porous. It lets air through but holds surface moisture. Some growers use waxed paper for extra protection, though it has the drawback of not breathing as well.

What you will not find in a proper wrapping is cling film. Plastic traps moisture and creates a microclimate perfect for mould — the exact opposite of what is intended.

A Valencian tradition with logic behind it

In Valencia, wrapping citrus fruit one by one is neither a trend nor a marketing gimmick. It is a practice that became established when oranges began to be exported to Europe in the late nineteenth century. The crates travelled by train and by ship, for days or weeks. Without modern refrigeration, paper was the only available technology for getting the fruit to its destination in good condition.

Today, with cold chains and fast logistics, the paper is still useful — particularly for fruit shipped directly from the tree without cold storage or post-harvest treatment. That is the case with our fresh oranges from Valencia, which are picked to order and arrive within 24–48 hours. The paper protects during that short but real journey.

When the paper is not needed

If you buy citrus to eat within a few days and keep it in the fridge, the paper is not essential. Its main function is for transport and medium-term storage. Once at home, what matters is keeping the fruit somewhere cool and dry, without piling it up.

Frequently asked questions

Is the wrapping paper recyclable?

Yes. Sulphite tissue paper is recyclable and compostable. If it carries printed text (brand, origin), it remains recyclable provided the ink is vegetable-based, which is standard in the citrus industry.

Can I reuse the paper to store the fruit at home?

You can, but it is not necessary if you plan to eat the fruit within a few days. If you want to extend the life of your citrus, keep it in the crisper drawer of the fridge without stacking. The paper helps more during transport than in the refrigerator.

Why are some supermarket citrus fruits not wrapped?

Because fruit that has been through cold storage and received post-harvest wax treatment does not need the extra protection. Paper wrapping is more typical of fresh, untreated fruit that is picked and dispatched directly.

Does the paper affect the taste of the fruit?

No. Tissue paper is neutral and inert. It transfers neither taste nor smell to the fruit. That is precisely its purpose — to prevent the fruit from absorbing external odours.
