Bananas, a staple in many vegan diets, are generally considered vegan due to their plant-based origin. However, recent advancements in food preservation techniques have raised concerns about the potential use of non-vegan ingredients in banana production. This article delves into the vegan status of bananas, exploring the potential presence of animal-derived substances and providing guidance for vegans seeking to maintain a strictly plant-based diet.
Are Bananas Vegan?
Traditionally, bananas have been considered vegan as they are a fruit derived from plants without any direct involvement of animal products. They are a rich source of essential nutrients, including potassium, vitamin C, dietary fiber, and antioxidants, making them a valuable addition to a vegan diet.
Potential Non-Vegan Concerns
Despite their inherent vegan nature, concerns have emerged regarding the use of chitosan, a substance derived from crab and shrimp shells, as a spray-on pesticide to extend the shelf life of bananas. Chitosan forms a protective coating on the banana peel, preventing premature ripening and spoilage.
Impact on Vegans
For vegans who strictly adhere to a plant-based diet, the presence of chitosan on bananas poses a dilemma. Consuming bananas treated with chitosan would violate their dietary principles, as it involves the indirect consumption of an animal product.
Vegan-Friendly Alternatives
To ensure a truly vegan banana experience, opting for organic bananas is recommended. Organic farming practices prohibit the use of synthetic pesticides, including chitosan, guaranteeing that the bananas are free from non-vegan substances.
Additional Considerations
While the chitosan coating is primarily applied to the banana peel, there is a possibility that trace amounts may seep into the fruit itself. Vegans who are particularly concerned about this potential cross-contamination may choose to avoid bananas altogether or consume them sparingly.
Bananas remain a nutritious and generally vegan-friendly fruit. However, vegans should be aware of the potential use of chitosan as a pesticide and make informed choices based on their individual dietary preferences. Opting for organic bananas or avoiding bananas altogether can ensure a strictly plant-based diet.
What Is Chitosan Used For?
It seems ludicrous (for lack of a better word) that your nutrient-dense, fiber-rich, potassium-rich, vitamin B6 powerhouse, the humble banana, might contain crabs and prawns, but is that really the case? Well, to begin with, we should note that there are numerous steps involved in the production of chitosan, from the animal to the final product. First, the naturally occurring polymer chitin needs to be removed from the exoskeletons of the crustaceans. After that, an alkali is applied, most frequently sodium hydroxide, and this is processed further to produce chitosan.
On the one hand, many vegans will deem this irrelevant as the starting point is still an animal but on the other it is very clearly different to “eating crab”. Second, the chitosan is not actually eaten as it (or rather a solution containing it) is applied to the exterior of bananas, so unless you consume the skin, you won’t be actually eating it. Whilst you can eat banana skins and they deliver extra fibre and potassium, most people, in the UK at least, do not consume them.
However, as previously mentioned, this argument will mean little to many vegans because, whether they consume the chitosan or not, the fact that it was utilized will make more stringent vegans view a banana that has been chitosan-treated as non-vegan.
Is Chitosan Really Used?
After conducting additional research on this matter, it appears that chitosan may not be utilized very often, if at all. Fact from fiction is getting harder to distinguish, and the way the Internet operates can make matters worse. When more and more websites use the same information to report on a story, the facts may become skewed. Information that is “passed down the line” not only has the potential to become more erroneous over time, but paradoxically, it also has a tendency to gain credibility.
Sadly, we believe that the concept of coating bananas with chitosan may have led to this outcome. Without a doubt, studies have demonstrated that chitosan can prolong the shelf life of bananas. Furthermore, there is no question that this was extensively covered by the mainstream media, including a number of reputable publications.
Nevertheless, a lot of websites and print media publications have taken the evidence that chitosan was beneficial and gone much farther to generalize about its application. We got in touch with several grocery stores and banana growers to find out if they use chitosan. Specifically, we inquired about its use after harvest rather than as a growth enhancer or biopesticide.
Most unhelpfully didn’t respond to us at all, but a few did. Tesco provided us with a detailed response that concluded with,
The whole response they provided was, to be honest, a little more detailed than we would have liked! They also said, “We can state that there would be no more presence of animal by-products than when using animal manures to fertilize organic field crops.” After we pushed them for more information, they responded on July 1, 2020, stating, “I can confirm that [chitosan] is not used post-harvest on any of our products.” ” Nice one Tesco!.
Waitrose also responded to us (thanks, guys!), and their response was pleasantly straightforward. They reported to us on June 27, 2020, saying, “I’ve been in contact with our buyer, who told me that our banana production does not use chitosan or other products derived from shellfish or other animal material.” ”.
Although Tesco and Waitrose might be exceptions, we find that difficult to accept. The more likely scenario, in our opinion, is that chitosan hasn’t been widely used—or maybe it hasn’t been used at all—to coat bananas and other fruit for whatever reason.
Since we are unsure of this, our advice is essentially unchanged. We believe that many vegans will consider the pre- or post-harvest use of chitosan in agriculture to be acceptable. If you disagree, though, the best way to find out is to ask the retailer (and good luck getting a response if it’s not Tesco or Waitrose!).
