Soy Sauce Bacteria Effective Against AllergiesKikkoman Corporation has discovered that lactic acid bacteria derived from soy sauce and other fermented foods are effective against allergies.
Kikkoman Corporation has discovered that lactic acid bacteria derived from soy sauce and other fermented foods are effective against allergies.
Specifically, the company has elucidated that tetragenococcus halophilus Th221, a kind of plant-derived lactic acid bacteria found in soy sauce, can induce the generation of interleukin 12 (IL-12), a substance that helps alleviate allergic symptoms.
In recent joint research with the Tokyo University of Agriculture, Kikkoman also discovered that several other plant-derived lactic acid bacteria from fermented foods, such as Leuconostoc mesenteroides, are able to induce the generation of IL-12.
Furthermore, in experiments on mice, they confirmed that these bacteria help alleviate allergic symptoms. In particular, their administration reduces serum IgE levels, an indicator of allergy.
