Great idea for using up banana waste – banana flour!

13/02/2015 //  by Michelle Berridale Johnson//  3 Comments

Press release from Lund University:

The Lund University students were asked to find ways of using these rejected bananas, as a part of their course work. After some brainstorming, they came up with the idea of a flour – meaning they could also use the banana peel, reducing waste further.

They experimented with a formula where they dried and milled the unpeeled bananas. Initially, the flour was too sticky since it contained too little starch. They then decided to boil the bananas first. Once the method was perfected, there was no need for any additives, meaning the flour consists of only banana.

”We set out to reduce waste, but quickly realized that the flour also has some health benefits. Banana peels contain dietary fiber, the flour is gluten-free – and because it is naturally sweet, you can lower the amount of sugar you use when you bake with it”, says Nathalie Knopp, one of the students in the group.

So far, the students have made pasta and cakes using the flour, with promising results. Cereals and pancakes are other foods they believe would be a good fit for their product.

Since bananas are made of up 80% water, you need quite a lot of them to make the flour. Also, the students only use organic bananas, as using the peel means avoiding pesticides becomes an issue. Even so, if fruit is being thrown out simply because its appearance is unappealing to shoppers, the students’ solution seems like a great alternative.

Finally… what does the flour taste like, then?

”It does have a subtle banana flavor. However, it’s very mild and pleasant, and depends on what other ingredients you combine it with”, concludes Natalie Knopp.

    so actually, when you make a smoothie with a banana, you dont need to peel it first!

    Is it possible to secure the production protocol from the students or Lund University?

    Afraid I have no idea – but it might be worth approaching them.

Could wireless monitoring devices be killing racehorses?

Regular readers may remember that back in August last year I alerted you to a posting on Arthur Firstenberg’s Cellphone Task Force site about phone masts and bird flu. Could there be a connection between the fact that the two wildlife sites in Holland and Northern France which had suffered catastrophic bird flu deaths were …

New distribution for Dr Joneja’s Histamine books

Dr  Janice Joneja is recognised as a world expert on histamine intolerance – or, to be more accurate, histamine excess. Although intolerance to histamine does exist it is extremely rare. Most of the 1% of the world’s population who are thought to experience histamine related symptoms are actually reacting to an excess of histamine in …

Can words heal?

Sticks and stones may break our bones but words can never hurt us. But is that true? Or, if words cannot literally hurt us, can they either help or hinder us in healing ourselves? This question was raised by a recent article in the Townsend Letter, an e-newsletter for doctors and laymen focusing on alternative …

Veg Power – making it fun

How come the food industry is so successful in persuading us – and our kids – to buy sweet, sugary, unhealthy food instead of healthy veg? Easy…. They are tapping in to the fact that our 10,000 year old DNA still believes that when we come across something sweet (ripe fruit in season, honey up …

Observing the speed limit

Rather grumpily, at 7.45am yesterday morning, I signed in to my on line ‘Speed Awareness Course’ – the alternative I had been offered instead of points and a fine. My crime? Doing 24mph on a 20mph road at 8.30 on a Sunday morning. The course was run by a group called TCC. Our ‘course leader’ …

Heavy Metal and chemical toxicity

Are you worried about the amount of metal and the number of chemicals that we come into contact with on a daily, indeed hourly, basis? Not all of them (at a rough estimate there are over 150,000 chemicals in constant circulation) are bad. Indeed, many are crucial to our daily lives. But many are bad, …
