Effects of steaming and drying processing on Korean rice wine (Makgeolli) with deodeok (Codonopsis lanceolate)

초록

The physicochemical properties of deodeok (Codonopsis lanceolate) was investigated in relation to the different steaming time and cycles of steaming and drying (S/D). Additionally, the quality characteristics of Makgeolli with different amount (0-0.45%) of steaming and drying deodeok (SD) were measured comparison to non-steaming and drying deodeok (NSD). L* values of deodeok tended to decrease as the number of S/D cycles and steaming times increased, while BI showed the opposite trend for L* values. Reducing sugar increased significantly from 1 to 3 S/D cycles and decreased thereafter (p<0.05). Also, processed with steaming for 4 h and 5 S/D cycles had the highest antioxidant properties. Principal component analysis (PCA) revealed that the S/D process notably influenced the properties of deodeok. Quality characteristics of Makgeolli showed that 0.45% SD resulted in higher antioxidant properties than control or NSD.
