Because ochratoxin A recovery level of Makgeolli is lower (50%) than those of other commodities such as rice, barley, and beer, Makgeolli was evaluated to improve the recovery and enable routine analysis. Use of 3% sodium bicarbonate instead of phosphate-buffered saline as homogenizing solution provided good recovery of ochratoxin A (80%) spiked in Makgeolli at level of l ppb. To determine if this analytical method is reliable for ochratoxin A detection in Makgeolli, survey was conducted for ochratoxin a in 30 sterile Makgeolli samples retailed in Korea.
