Kimchi Mini Quiz
Test your knowledge with these top questions!
To safely send the dish kimchi to space, scientists heavily modified it to prevent what danger?
Active microbes in kimchi produce carbon dioxide during fermentation. Scientists sterilized the space version with radiation so the gas wouldn't build up and pop the bags.
Traditional Korean cooks bury earthenware pots of kimchi underground during winter to achieve what goal?
The earth acts as natural insulation during harsh winters. It keeps the porous pots, called onggi, just above freezing so the cabbage ferments slowly without freezing solid.
South Korean families gather every autumn for the cultural event "gimjang" to perform what task?
This communal practice ensures families have enough preserved vegetables to survive the winter. In 2013, UNESCO recognized gimjang as an Intangible Cultural Heritage.
South Korean appliance makers design specialized kimchi refrigerators to manage what factor?
These appliances mimic the stable environment of traditional buried clay pots. By precisely controlling the temperature, they slow bacterial growth to extend the ideal flavor.
To prevent fermentation gases from exploding in space, what South Korean national dish was irradiated for a 2008 orbital flight?
Millions of dollars were spent researching how to neutralize the dish's lactic acid bacteria with radiation so astronaut Yi So-yeon could eat it safely.
Buried in soil to keep temperatures stable, what traditional earthen pots are historically used in South Korea to ferment kimchi?
Onggi are unglazed, microporous ceramic vessels that allow the fermenting cabbage to breathe while effectively keeping out rainwater and insects.
Traditional Korean cooks bury earthenware pots of kimchi underground to achieve what goal?
Soil insulation keeps the fermenting cabbage cool during the hot summer months and prevents it from freezing solid during South Korea's harsh winters.
South Korean scientists modified kimchi for astronauts to prevent what dangerous event?
Active fermentation continuously releases carbon dioxide gas. This pressure buildup could easily rupture sealed containers and damage nearby spacecraft equipment.
