Cavendish Banana

Description

Cavendish is the banana the export trade runs on, and it is the most demanding fruit we ship. Not because it is fragile in the way a papaya is, but because it is alive and on a clock: a banana leaves the farm green, spends the voyage refusing to ripen, and is then ripened on purpose at the far end. Get any part of that wrong and the container arrives either yellow or dead.

Dragon Hub grows and packs Cavendish for buyers who ripen at destination — supermarket programmes, ripening houses and wholesale importers. What follows is what we ship and what we need from you to quote it properly.

What we ship

Fingers run 17 to 20 cm. For reference, the Codex and EU export standards set the minimum at 14 cm, so this is comfortably above the floor and in the range most retail programmes ask for. Fruit is cut into hands and clusters, dehanded and washed at the packhouse, and packed in the same working day it is cut.

Cartons are 10 kg or 13 kg. The 13 kg box is the standard export carton for most Asian and Middle East programmes; the 10 kg box suits shorter routes and buyers who want a lighter handling unit on the shelf floor. Both are single-piece boxes with a polyethylene liner, which is what holds the atmosphere around the fruit during the voyage — the liner is not packaging, it is part of the cold chain.

Length is only one of the things a banana specification has to state. If you are writing or revising a spec, our guide to Cavendish banana grades and sizes covers how length and grade are actually measured, what each class allows, and what buyers most often leave out.

Green life, not shelf life

Most fruit is bought on shelf life. Bananas are bought on green life — the number of days the fruit will stay green after harvest before it starts to ripen on its own, with no ethylene applied. It is the only number that decides whether your route works.

Green life is not a fixed property of the variety. It is set by the maturity at which the bunch was cut, by how quickly field heat came out of the fruit, and by how steadily the temperature was held afterwards. Fruit cut a little fuller eats better but travels shorter; fruit cut leaner travels further but can arrive thin. That trade-off is the whole of banana buying, and it is decided before the container is sealed.

So the useful question at enquiry is not “how long does it keep” but “how many days from our packhouse to your ripening room” — port to port, plus clearance, plus the run inland. Give us that number and we will cut to it. Give us a destination without it and any supplier is guessing.

The temperature window

Bananas have the narrowest temperature window of anything we export, and it is narrow at both ends.

Too cold is worse than too warm. Below roughly 13 °C bananas suffer chilling injury, and the damage is permanent: the peel goes dull and grey-brown, the vascular strands under the skin darken, and — the part that costs money — the fruit will not ripen properly afterwards. It stays hard, or it turns a muddy yellow with green shoulders and no flavour. Nothing in the ripening room reverses it. Worse, the fruit can look acceptable when the doors open and only fail three days later in the ripening room, which is the point at which it becomes a claim.

Too warm and it ripens on the water. Above about 15 °C the fruit begins to ripen in the container, and ripening bananas produce ethylene, which ripens the boxes around them. A container that starts turning does not arrive partly ripe — it arrives fully ripe, all of it, and it is unsaleable to a buyer who was expecting green fruit.

The working figure is 13 – 14 °C, held steady, with air circulation through the boxes and pulp temperature checked rather than assumed. Steady matters as much as the number: fruit that swings between 12 °C and 16 °C across a voyage arrives worse than fruit held slightly off-target the whole way.

Ripening happens at your end

We ship green. Bananas are climacteric, which means they ripen on demand when ethylene is applied — so the colour stage your customer sees is something you control, days before you need it, rather than something that arrives by luck.

In a ripening room the fruit is dosed with ethylene and brought up over roughly four to eight days, on a schedule chosen to land at a particular colour stage on a particular date. A faster schedule runs warmer and gives colour quickly; a slower schedule gives better eating quality and a longer life on the shelf. This is your decision, not ours, and it is why green fruit is worth more to you than fruit that has already started.

If you do not have ripening capacity, say so at enquiry. It changes the route, the transit time and the maturity we cut at, and it is not something to discover after the first container.

Supply through the year

Bananas do not have a season in the way mango or pomelo do. The plant fruits continuously, so harvest runs every week of the year and volume is a matter of planted area rather than of calendar. That makes bananas the anchor line in a year-round programme: the item you contract first and build the rest of the container schedule around.

Two things do move with the calendar. Fruit fills more slowly in the cooler months, which generally means better eating quality and slightly longer green life. And the weeks around Tet, the Vietnamese lunar new year, tighten labour and shipping across the whole country — if your programme runs through that window, book it early rather than assuming normal lead times.

What to send us for a quote

• Finger length and grade, and the class you are buying to
• Carton weight — 10 kg or 13 kg — and whether the print is yours, neutral or ours
• Destination port and, importantly, total days from our packhouse to your ripening room
• Whether you ripen at destination, and at what colour stage you sell
• Volume per shipment and frequency across the year, not just the first container
• Any market-specific requirement — residue testing, certification, traceability codes
• Incoterm

Dragon Hub processes, packs and exports Vietnamese fruit to supermarket and wholesale buyers across Asia and the Middle East. Cavendish bananas sit alongside mango, pomelo, seedless lime, dragon fruit and coconuts in our product range.

Frequently asked questions

What finger length do you supply?

17 to 20 cm. The Codex and EU export standards set a 14 cm minimum, so this sits well above the floor and in the range most retail programmes specify. Length is measured along the outer curve of the finger, on the middle finger of the outer row of the hand.

What is green life, and why does it matter more than shelf life?

Green life is the number of days the fruit stays green after harvest before it starts ripening by itself. It decides whether your route works. It is set by harvest maturity, how fast field heat is removed and how steadily temperature is held — so it is a result of how the fruit was handled, not a fixed property you can look up.

Why can bananas not be shipped colder to make them last longer?

Because below about 13 °C they suffer chilling injury, which is permanent. The peel dulls and greys, the strands under the skin darken, and the fruit will not ripen properly afterwards — it stays hard or turns muddy yellow with no flavour. It often looks acceptable on arrival and only fails days later in the ripening room.

Do you ship ripe or green bananas?

Green. Bananas are climacteric and ripen on demand when ethylene is applied, so ripening is done at destination over roughly four to eight days on a schedule you choose. That gives you control of the colour stage on the date you need it, which fruit already ripening in transit cannot.

Are Vietnamese bananas available all year?

Yes — the plant fruits continuously, so harvest runs every week of the year and volume depends on planted area rather than season. Fruit fills more slowly in the cooler months, which usually means better eating quality. Book early around Tet, when labour and shipping tighten nationally.
