Red yeast rice has been used to produce alcoholic beverages and various fermented foods in China and Korea since ancient times. It is produced by fermenting cooked rice kernels with the mold Monascus purpureus, which then turns rice into reddish purple kernels because of its pigmentation ability. This fermentation process results in the production of secondary metabolites called Monacolins which is very similar to natural statins– known to have cholesterol-lowering effects like the drug Lovastatin. Among these monacolins, Monacolin K is considered to be the most effective for lowering plasma cholesterol.
