A group of Technion students has come up with a plan to feed a protein-scarce world – with algae-based falafel. And no, this isn’t a load of balls.
With the world facing a global protein shortage – and the population expected to grow to 9.8 billion people by 2050 – ways are needed to feed them all. And with finite land and water resources, this will be quite a challenge.
A team of graduate students from the Technion’s Biotechnology and Food Engineering Faculty invented Algafalafel , which last month won first prize at the EIT Food Project competition held at the university.
The Algafalafel are enriched with spirulina, which is a “biomass of blue-green algae which produce their own food by photosynthesis without a living organic carbon”, according to the university. Dried spirulina contains 5 percent water, 24 percent carbohydrates, 8 percent fat, and about 60 percent protein.
Chickpeas, the main component of falafel, are also considered to be rich in protein. However, their protein content is only 20 percent.
The “tahini” on the falafel is also enriched with astaxanthin, “a health-promoting compound found naturally in certain algae and seafood”, said the Technion.
Spirulina, which grows in both fresh and saltwater, is one of the foods that has long been suggested as scientists tackle the concerns of food insecurity. Cultivating spirulina requires less land and water than producing cattle or poultry.
While life in Israel has returned to normal and hopes are high that Britain is set for a summer without restrictions thanks to vaccines, for billions around the world there is no such imminent light at the end of the tunnel. In the majority of countries around the globe, particularly the poorest, the vaccine rollout has barely kicked off.
That's why Jewish News, the leading source of news and opinion for the entire UK community, is throwing its full weight behind UNICEF’s VaccinAid campaign by using this platform usually reserved for encouraging donations towards our own journalism to instead urge our readers around the globe to perform the greatest mitzvah: saving a life.
We have never before done this for any charity fundraiser but it's hard to recall a campaign that affects so many people, and indeed an entire planet aching for a return to normality. Just like the Chief Rabbi and Rachel Riley, we hope to boost the mission to deliver two billion vaccines, 165 million treatments and 900 million test kits around the world by the end of this year.
Please donate as much as you can, in the spirit of the Talmudic sages: “to save one life is to save the world entire”
