Red Yeast Rice
Red yeast rice (simplified Chinese: 红曲米; traditional Chinese: 紅麴米); pinyin: hóng qū mǐ; literally: "red yeast rice"), red rice koji (べにこうじ, lit. 'red koji') or akakoji (あかこぎ, also meaning 'red koji'), red fermented rice, red kojic rice, red koji rice, anka, or ang-kak, is a bright reddish purple fermented rice, which acquires its colour from being cultivated with the mold Monascus purpureus.
Red yeast rice is what is referred to as a "koji" in Japanese, meaning 'grain or bean overgrown with a mold culture', a food preparation tradition going back to ca. 300 BC. In both the scientific and popular literature in English that draws principally on Japanese, red yeast rice is most often referred to as "red rice koji".
