FOOD HIGHLY CONTAINING PYRROLOQUINOLINE QUINONE, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide food highly containing pyrroloquinoline quinone.

SOLUTION: The method for producing food highly containing pyrroloquinoline quinone comprises separating and collecting a solid substance precipitated by adding inorganic salt to liquid material produced by separating solid content from a cultured product obtained by culturing Bacillus natto using soybeans or a soybean containing-processed product as a culture medium. The food highly containing pyrroloquinoline quinone obtained by the method contains the pyrroloquinoline quinone in a concentration of ≥100 ng/g.
