A surprising solution might be found in a food that was eaten by the Aztecs hundreds of years ago: spirulina.

While nowadays better known in the form of dietary supplement pills and superfood powders, spirulina is in fact a biomass of blue-green algae. It was a daily food source in the Americas until the 16th century, when it lost popularity as lakes were drained for agriculture and urban development.

Spirulina produces its own food by photosynthesis, and its cultivation requires much less land and water than that needed by cattle or poultry, making it an eco-friendly alternative to feed the world.

A team of graduate students from the Technion-Israel Institute of Technology found one very Israeli answer to that – a falafel enriched with spirulina.

For an extra kick, they served it with tahini enriched with astaxanthin, a health-promoting compound found in certain algae and seafood (it’s responsible for salmon’s reddish color and flamingo feathers’ pink hue).

It took the students – Meital Kazir, Yarden Abuhassira-Cohen, Hani Shkolnikov, Hila Tarazi and Ina Nephomnyshy – a year to conceive, develop and produce their “Algalafel.”

The hard work paid off, as the team recently won first prize in a competition held by EIT Food, a European initiative focused on the food sector.

The second prize in the two-day event hosted by the Technion went to a team from the German University of Hohenheim for “Algini,” a lentil-based product enriched with spirulina. Third place went to students from Finland’s University of Helsinki, who created “Spurtti,” a vegan oatmeal dessert enriched with spirulina.

EIT Food supports creative and economically sustainable initiatives that promote health, access to quality food and the environment. The project included three industrial partners: Israel’s Algatechnologies, which supplied the raw microalgae materials used by the competing teams, Germany’s Doehler and Finland’s Fazer.
