Food: Microalgae could help meet global demand, study finds


Scientists at Cornell University say they might have discovered a technique to meet the world’s rising meals calls for: algae.

Research revealed in September within the peer-reviewed journal Oceanography suggests microalgae grown onshore could present a sustainable supply of meals and vitamins globally.

“Microalgae takes up CO2 from the air and likewise makes use of little or no land, no freshwater and little or no inorganic phosphorus to provide meals, in order that overcomes the issues of present meals techniques,” Xingen Lei, a co-author of the study and professor of animal science at Cornell, advised CTV’s Your Morning on Thursday.

The study’s authors say marine algae-based aquaculture could produce greater than the full global protein demand projected for 2050, providing “a greater supply of high-quality dietary protein, important amino acids, and different micronutrients relative to terrestrial vegetation.”

Since it doesn’t require soil, irrigation and the open use of fertilizer, the researchers say marine algae doesn’t must compete with agriculture for arable land and freshwater, probably decreasing carbon emissions and the lack of biodiversity by actions resembling deforestation.

Using CO2, easy vitamins and solar or synthetic mild, Lei says microalgae could be produced on a big scale.

As far as making it interesting to eat, Lei advised CTV’s Your Morning that this could contain selecting a extra flavourful species to develop or just extracting the vitamins and mixing it with different elements to make a dish extra palatable.

A writeup revealed by the Cornell Chronicle on Oct. 6 famous that Lei and his colleagues discovered including algae to rooster feed additionally tripled the quantity of omega-3 fatty acids in eggs in comparison with regular ones.

“We have a possibility to develop meals that’s extremely nutritious, fast-growing, and we will do it in environments the place we’re not competing for different makes use of,” Charles Greene, professor emeritus of earth and atmospheric sciences at Cornell and the paper’s senior writer, mentioned within the Chronicle story.

“And as a result of we’re rising it in comparatively enclosed and managed amenities, we do not have the identical type of environmental impacts.”
