Algae Guacamole in Space

A​ biology lab at San Diego State University is working with a NASA grant to create a recipe for guacamole that will travel to space. The project is aimed at diversifying the diet of astronauts, and the researchers chose the guacamole to lift the space travelers’ spirits as well. Microalgae is an essential ingredient of this guac, meant to bolster it with antioxidants to help protect astronauts from the high levels of radiation on the spaceship.

One of the researchers adds what he calls molecular sensory science, which improves the flavor of food — not with additives, but by chemically manipulating the compounds in it. This can enhance some amino acids and sugars in the algae and gives it a good taste when added to the guacamole.

In February of 2024 the researchers expect to present their space guac concoction at NASA’s Human Research Program Conference in Texas.
