In case you have been questioning whether or not it’d be doable to ferment meals in area, the reply is seemingly sure. In a examine printed within the journal iScience, researchers from the US and Denmark say they have been in a position to make decent-tasting miso on the Worldwide House Station — however the taste and scent was distinct from that of miso made on Earth. Whereas it nonetheless scored properly within the style assessments, with related scores to Earth miso in qualities like umami and saltiness, the ISS miso was discovered to style nuttier and extra roasted than the same old stuff.

The staff suggests the findings mirror a kind of “area terroir,” taking part in off the time period usually utilized in relation to wine grapes to explain distinctive, location-specific taste traits. For the examine, the researchers despatched a package deal containing the miso paste substances (cooked soybeans, rice koji and salt) to the ISS in March 2020, and let it ferment for 30 days. Additionally they began miso batches again at house in Cambridge, MA and Copenhagen, Denmark, and monitored the environmental circumstances of every setup. After a month, the area miso was despatched again and analyzed compared to the Earth batches.

“There are some options of the area surroundings in low earth orbit — specifically microgravity and elevated radiation — that might have impacts on how microbes develop and metabolize and thus how fermentation works,” co-lead writer Joshua D. Evans of Technical College of Denmark mentioned in a press release. “We wished to discover the results of those circumstances.”

Not solely have been there variations in taste, together with the notable roasted nuttiness of the area miso, but additionally within the microbial composition of the misos. The staff concluded that “total, the area miso is a miso,” however says the findings “counsel a particular fermentation surroundings in area.”
