A Guide to Those "Baby" Bananas – and What They Prove

on_bananacostume_baby.jpg

Huggable, lovable – but not the kind of baby banana that I’m talking about.

Though the vast majority of bananas we buy – statistically, all – are of the endangered Cavendish variety, there’s a good chance you’ve seen something else, these days and if you’re a banana-type (or have become one), you might have wondered: what are those little bananas?

Both Chiquita and Dole offer versions of the half-sized fruit, with Chiquita selling them under the “Minis” brand, and Dole offering them as “Baby” bananas.

In the “big” banana world, there’s absolutely no difference between what Chiquita, Dole (or any other commercial banana importer) sells: everything is Cavendish. Action surrounds small-time fruit. For the first time in over a century, the two biggest banana companies are slugging it out for a market niche with different varieties.

The Chiquita “Mini” is a breed called Pisang Mas, originally from Malaysia, but now – like all bananas imported to the U.S. – grown in Latin America.

Dole actually sells three different varieties under the Baby band nameOrito, Lady Finger, and Manzano.

The fruit are tough to find, since they’re in various stages of test-marketing, as well as subject to seasonal variation. They also cost about three times as much as their ordinary counterparts. But they’re worth seeking out, and not just because they prove – possibly for the first time to the average American consumer – that there’s something beyond the generic banana. Though the four types share some characteristics (beyond size), they’re also quite different from each other.

I’ve put together a guide to the four varieties, but one caveat: no great banana arrives easily. Dole doesn’t distinguish between the three types it offers – they’re all labelled the same – so side-by-side taste tests are going to be tough. But persevere. The results will be worth it (and ignore the for-kids marketing that the banana giants have attached to the product. Sure, they are great after school, as Chiquita’s says. But this isn’t baby food.)

Oh, and one more thing, and you MUST do this, or else your adventure in little bananas will surely fail: LITTLE BANANAS TASTE HORRIBLE UNTIL THEY’RE RIPE – AND RIPE, FOR LITTLE BANANAS, IS NOT YELLOW! You need to let the fruit turn brown or else it will not be sweet or soft enough. This will go against every banana extinct you have been trained to adhere to. Trust me.


CHIQUITA’S PISANG MAS (BRAND NAME: MINI)

NEW MINIS CLUSTERsm



  • Super sweet – but only when very ripe. This is a fruit that is awesome when “peaking,” but the peak can be hard to catch. When not peaking, not so good.
  • Thin-skinned, so it bruises easily.
  • IDENTIFYING: Easy. The only one Chiquita sells.

DOLE’S BABY (TYPE II – ORITO):

Orito

Orito Banana, from Ecuador’s Goldenforce.

  • Possibly the sweetest of the four varieties – making it (when ripe – see above) one of the best bananas for smoothies.
  • Grown almost exclusively in Ecuador, where labor laws are weak, making this a very high-margin, high-political cost fruit.
  • Identification: Chubby. If the country of origin is Ecuador, almost definitely Orito.

DOLE BABY (TYPE II – LADY FINGER):

  • Similar peaking/ripening characteristics as Pisang Mas.
  • Doesn’t easily turn brown when cut, making it perfect for fruit salads.
  • Susceptible to Panama Disease Race One, the malady that killed the first worldwide commercial banana crop – and which still exists today.
  • Closer to a mini-Cavendish in appearance. Slender(ish.) Super popular in Australia, so if you’ve got an Aussie in tow ask him or her for identification help.

DOLE BABY (TYPE III – MANZANO/APPLE):

  • Falls into the “apple” banana category – giving it a unique, tangy-sweet taste. Much less bland than our Cavendish, but some banana marketers have traditionally believed that consumers would reject such a different-flavored fruit.
  • Definitely the most “gourmet” banana of the bunch.
  • Small ripeness/sweetness issue. Can be eaten a little bit less brown if you like the tart flavor, but you must wait beyond brown – until the skin is black – for the highest sugar content (which will give you a fabulous, multi-dimensional bite.)
  • Difficult to grow in wet, lowland conditions
  • Easier to find than others – sold under many brand names (or none at all) in Latin markets, where it is often a Mexican import.
  • Identification tips: Significantly fatter, chunkier than Cavendish and probably the other little bananas, as well.

Once you’ve tried a couple, it’s worth thinking a bit about what this all means in a world where the single fruit that we generally eat is threatened with practical extinction. The arrival of these alternate bananas in our markets shows that variety is possible, and that the commercial banana companies are willing to experiment with it (even with the for-kids-only marketing tilt.)

Despite this, the banana companies are likely very hesitant to move the fruit into any testing beyond these niches. The reason is that – according to conventional industry wisdom – there’s simply too much “wrong” with the pint-sized fruit. The main arguments against mainstreaming mini-bananas include:

  • Ripening. All of these fruit must be quite dark to taste good. The banana companies are (rightly?) afraid that the typical consumer is so well conditioned toward seeing a golden banana as perfect that wider acceptance would simply never occur.
  • Production. The varieties in question can’t be grown as broadly, geographically speaking, as Cavendish. There probably isn’t enough land in Latin America to make any one of these varieties anything near to a market share winner.
  • Shipping: These are thin-skinned fruit. Today’s banana supply chain is so industrialized that the little fruit don’t fit into it, requiring costly “custom” handling all along the way. For an industry built on turning an exotic tropical fruit into a commodity as cheap and ubiquitous as a fast-food burger, the idea of reinventing itself to handle more complex products may feel both financially and culturally risky.
  • Marketing. People buy bananas by the bunch. Would the price/weight equation shift with a smaller banana as our main choice, or even as a more prominent alternate? The banana has been America’s favorite fruit – by far – since the 1920s. Changing the very size, shape, and price of that fruit into something completely new would be a terrifying prospect for the banana companies, which introduced the fruit to us, struggled to make it our favorite, and have fought – often spilling blood – to keep it exactly the same ever since.

Despite all this, change has to come.

All of these arguments are based on a single premise: that the banana we eat today will last forever. It won’t. It might not even last a decade.

The truth is that, as a living organism, all bananas have strengths, and all bananas have weaknesses. The biggest weakness the world’s banana crop has today, though, has nothing to do with the fruit itself: it has to do with the human folly of relying on a single variety to feed millions.

The half-sized varieties from Chiquita and Dole are not, I’m told, doing all that well at the market. Some of Dole’s farms in Ecuador that were devoted to the Orito fruit are reported to have closed. But the proof of concept – getting the fruit from there to here, figuring out how to market and sell it - has been accomplished, and despite my frequent criticism of the banana companies, there’s credit deserved for that.

The experiment, however, needs to be seen as more than just marketing. The biological common sense – and necessity – of breaking the Cavendish monoculture needs to be acknowledged, as well. It is in combining salesmanship with this common sense that will lead the industry away from the dead end it is now rapidly heading toward. The “Mini” and “Baby” fruit provide a blueprint – even, focused as it is on children, it appears to have been written in crayon.

Chiquita Acknowledges Panama Disease as Threat

ploetz4lg.jpg

Panama Disease-ravaged plantation in Asia (from Plant Health Progress.)

In an interview with the Cincinnati Enquirer, Chiquita CEO Fernando Aguirre – for the first time – publicly acknowledged the existence of Panama Disease (the incurable malady that wiped out the world’s banana crop in the first half of the 20th century, and that has devastated much of Asia over the past two decades) – in relation to his company’s mainstay product, though he downplayed the threat to the point of barely admitting it existed.

The story is headlined “New banana disease poses threat: How serious is open to debate.” In it, Aguirre described the disease as “limited,” and asserted that – when the disease arrives in Latin America – quarantine measures would “pre-empt and prepare” the advance and effects of the malady. I was interviewed for the story, and I disagreed, pointing out that such measures had failed most everywhere they’ve been tried in the past.

I was glad to see that the reporter, James Pilcher, also contacted Randy Ploetz, the scientist who is probably the world’s best authority on the fungus. Ploetz is less grim and more circumspect than I am (as well as a lot smarter than me), but he’s still way down on the fencing-your-farm idea: international quarantines will not work,” he said. “If it did get over to Latin America somehow, it is almost impossible to stop. When and if that will happen. No one can say for sure.”

I’m quoted in the story as saying that the Cavendish banana is a “dead end.” That’s something I’ve come to believe even more since I wrote the book. None of us – not the CEO of the world’s largest banana company; not a dedicated scientist; nor an author who has books to sell – knows when Panama Disease will hit. But what I suspect we all know is that the Cavendish is indeed a biological (and therefore, ultimately, a commercial) cul-de-sac. Breeding a new version of the banana we all eat is nearly impossible. It is totally sterile. It produces no seeds. (Each Cavendish is a genetic duplicate of the other. That’s why each gets sick when the other does.) This makes it a poor candidate as a parent to any new banana, except if genetic engineering is used, a technique Chiquita and most consumers reject.

The answer is diversity: a robust banana aisle with four, five, or six different kinds of fruit. Those varieties are out there. The technology needed to deliver them to market – to keep them fresh and intact from the places they’re grown to the places they’re sold – would be considerable. But it be worth the investment. Right now, at my local Safeway, I can buy four kinds of peaches, five kinds of apples, four kinds of lettuce, and more. Why not bananas?

When Panama Disease struck and destroyed the earlier breed of banana that our grandparents ate, Chiquita executives claimed that they knew how to protect their fields from the disease. They spent years saying so. They were wrong. There has never been a technical solution to Panama Disease. In 1960, as the last plantations were succumbing to the old blight, Chiquita was on the verge of bankruptcy. It had spent decades denying that there was a problem. It then wasted more time trying to find an answer using a means that didn’t work. It came close to destroying its franchise product. Chiquita can make the same mistake again. It has already taken willful steps down that path, and it doesn’t even know it. Though Aguirre is right in saying that the danger has yet to arrive, the danger will arrive, and the solution Aguirre outlines absolutely will not work.

My key takeway from the Enquirer story: Chiquita acknowledges a problem on the horizon – and it has publicly embraced a strategy that cannot work.

As far as diversity is concerned, Aguirre said that the company has “been working for a number of years on different opportunities to grow different bananas.”

OK, readers. I am warning you right now: RANT ALERT!!!!

I can’t stand this kind of PR-speak. What the heck did the Chiquita CEO even say just there? I mean, these are bananas. Bananas! India, the Philippines, the South Pacific, and even Brazil offer dozens of wonderful banana types that might delight and intrigue American consumers. I’ve tasted them and they’re freakin’ AWESOME. They taste BETTER than ours. Haagen-Dazs to bucket vanilla better! Don’t “work” for “a number of years” on “opportunities.” Just grow some danged fruit and sell it to us! You’re CHIQUITA! Your JOB is to sell us bananas!

JIMINY CRICKET!

OK, I’m feeling better now. The point is that there are plenty of ways to get Panama Disease mitigated before it gets here, and the first step is to not put all of our bananas in the Cavendish basket.

One more thing: for years before the Gros Michel – the old banana – went functionally extinct, Chiquita executives not only denied that there was a problem, but they also denied that the Cavendish was a solution. It was a competitor that came up with the proper techniques needed to grow and ship the Cavendish that made it a viable supermarket banana. That competitor was Dole, whose market share tripled and has barely declined since. A new competitor, with a new banana, may be waiting for Chiquita as this round of Panama Disease emerges – and this time around, Chiquita may not be so lucky as to be so unlucky.

Report: First Field Test of Genetically Modified Cavendish

Cavendish is our supermarket banana – the one that’s under threat from the newly-remerged Panama Disease (see here for more info.) The Cavendish banana is absolutely seedless and sterile, so it cannot be bred conventionally; the only sway to ensure its future as a commercial fruit would be through genetic engineering (the alternative would be to allow the Cavendish to die out and replace it with a different – and as yet unidentified – banana variety.) Now, according to a news report from the Australia Broadcasting Company, a project spearheaded by Australian scientist James Dale, who runs the Queensland University of Technology’s Centre for Tropical Crops and Biocommodities, has begun the field test of such fruit – the first time lab-modified Cavendish have ever been put to large-scale outdoor trial. The test, the story says, will be “to improve the nutrient content and disease resistance of Cavendish bananas.”

Australia is in desperate banana straits right now, having lost much of its crop to poor weather and a subsequent Panama Disease attack. The field tests are partially being funded by a grant from Microsoft founder Bill Gates. (Dale, by the way, prefers to use the term “biofortification” to describe genetically engineered fruit – one of a long list of proposed terms for such processes, including “genetically modified,” “transgenic,” “GM,” “GMO,” and others. The desire to come up with a less-scary name for lab-developed foods is understandable, but misguided. The real problem is that people have been misled into thinking that all genetic modification of foods is terrifying. The responsibility for this comes partially from big agricultural companies who have behaved terribly when they have introduced modified products – but also from consumer groups who oppose all forms of genetic modification while failing to understand even the basics of the science behind it. )

Comment: The Australia trials will likely horrify some folks – possibly because earlier tests of genetic bananas weren’t focused on supermarket fruit, and this brings the prospect of a so-called “Frankenbanana” closer to home. But genetic engineering isn’t an absolutely scary prospect, and this kind of work is needed with bananas, both because they’re a vital subsistence food, and because they’re such a weak organism. And the Cavendish is a very safe banana to experiment on: with no seeds or pollen, there is zero – absolutely zero – chance of it the kind of cross-crop contamination occurring that we’ve seen with engineered corn. Bananas need a lot of help to survive – and the lab is one of the places that help is going to come from. Not that the Down Under effort is entirely altruistic, I’m sure: if a Panama Disease-resistant banana can be built by Dale and his team, they’ll also have built a gold mine.

This is so yuck I won't even comment…

display_product_661.jpg

I’m sorry for this picture.

Click the link, to the Daijiworld newspaper, to find out the results of the study, if you dare…

Bangalore, May 29: Nagasandra, a village 50 km from Bangalore in Doddaballapur taluk, isn’t any different from the hundreds of others surrounding it. But in a remote corner of this small village is a 1-acre banana plantation that has been part of a unique research project: a study on the effect of anthropogenic liquid waste on soil properties and crop growth. In lay-man terms, it is a study on how human urine can be used as fertilizer in agriculture…

Read my article on Panama Disease in "The Scientist"

logo.gif

The most controversial part of my book is my assertion that biotech is key to saving the banana. I came by this assertion with a lot of difficulty – initially believing that most genetic engineering in our food supply was a bad thing. But, as usual, the issue isn’t black and white. With bananas, the shade of gray is especially green.

Bill Gates funds Banana Research

bill-gates-mugshot.jpg

The Bill and Melinda Gates Foundation has begun one of the largest privately-funded banana genetics research projects; the greenhouse breeding program is concentrating on subsistence bananas – the kind millions of people in the African highlands depend on as their primary source of nutrition – and using DNA engineering and traditional breeding techniques to increase levels of vitamin A and iron in those fruits.

Those are worthy goals, but I find it interesting that building disease resistance – the most important thing that needs to happen in the area surrounding Lake Victoria, where fungal wilts are rapidly destroying banana crops – seems to be a secondary goal, at least according to the article linked above. The project is being run by James Dale, a well-known banana biotech researcher who is quoted in my book.

Meanwhile, in Africa, some Gates foundation work is seen as controversial, precisely because it is technology-oriented. My feeling is that bananas – because they are quite difficult to breed, and because it is very late in the game in terms of improving their strength in the field – require as much technology as they can get. In this case, perhaps, this may be a version of Windows that is able to prevent viruses (sorry.)
