Red yeast rice (RYR) is the product of fermented yeast by Monascus strains on rice, and has recently become a popular dietary supplement as a traditional food in Asia. RYR contains monacolin K substances known to inhibit cholesterol synthesis as efficiently as statin drugs. To determine the optimal rice cultivar for manufacturing RYR, 7 rice cultivars (Goami, Goami2, Sangjuchalbyeo, Seolgaeng, Saegyejinmi, Yeonghojinmi and Chilbo) were fermented using two Monascus strains (M. ruber KCTC6122 and KCCM60141 of M. ruber) in this study. The monacolin K content of Sangjuchalbyeo were 47.24 ppm on KCTC6122 cultures and 117.03 ppm on KCCM60141 cultures, respectively. Other cultivars, especially Goami and Goami2, which had less content of monacolin K could not seem to ferment normally because those didn’t show red color. These results imply that Sangjuchalbyeo can be optimal rice cultivar as a commercial RYR which is well fermented rice and has high content of monacolin K.
