Citrinin is a toxin that found in angkak. The allowance of Citrinin in angkak is 200 ng/g in Japan but its authorized limit is still under consideration in China and Europe. Therefore, monitoring of citrinin level should be performed in angkak extraction. This research investigated the influence of ethanol concentration and temperature for Monacolin K extraction from angkak or Monascus Fermented Rice (MFR). Levels of Monacolin K, citrinin and pigment were monitored by use of spectrophotometric method.
