Space Yogurt from Himawari Dairy is now available in Japan.
Himawari Dairy, a Kochi-area dairy manufacturer, reserved a seat aboard a Soyuz rocket that took off from Baikonur Cosmodrome this spring. The "passengers" were two strains of bacteria: lactic acid bacteria used in ordinary yogurt and a unique strain of Lactobacillus paracasei cultured from pickles preserved in the dregs of sake (called sake lees), which is thought to enhance the body's immunity to disease.
Cosmic radiation was expected to have an effect on the bacteria. "Lactic acid bacteria is delicate, so we are looking forward to seeing what happens," says company president Bunjiro Yoshizawa. "It will be nice if space travel improves the yogurt's flavor and boosts its immunity-enhancing properties."
After ten days in the harsh environment of rockets and near earth orbit, the samples were returned to the dairy for study.
According to Yoshizawa, about half of the bacteria died in the agar medium due to the harsh environment inside the rocket. The company claims that the strong, surviving bacteria gives the space yogurt a more full-bodied flavor than commonplace yogurts made with earthbound bacteria.
In Japanese, the yogurt is called Uchu O Tabi Shita Yogurt (literally: “yogurt that traveled in space”). You can get some for just one dollar per ninety grams; a space yogurt drink is also available for those on-the-go (astronauts, perhaps?).
