초록

The objectives of this study were to characterize the physicochemical properties of ginger (Zingiber officinale Rosc.) and the optimum extract processing condition to increase the solubilization efficiency of 6-gingerol and polysaccharides disintegration. The physicochemical properties were investigated under high-pressure enzyme (HP) and enzyme (WB) treatment conditions such as reaction time (1, 2, 3 h), pressure (50, 70, 100 MPa) and sample types, and cell wall degradation enzyme (hemicellulase, cellulase, pectinase, glucosidase, etc.) The effect of high-pressure enzyme treatment depending on sample types was significantly highest in the freeze-dried ginger powder. The optimum condition for high-pressure enzyme treatment was with Pectinex Ultra SP-L (Pec) enzymes for 2 h at 50oC and 100 MPa. Water soluble indexes increased 4.6 and 3.8 times more compared to CON (15.35%) while total polyphenol contents increased by 1.8 and 1.7 times compared to CON (1.43%). The total contents of indicator components such as 6, 8, 10-gingerol and shogaol was 1.53%, increasing 2.7 times more compared to CON (0.57%) with a significant difference (p<0.001). The high-pressure and enzymatic approach described in this study would be beneficial to food industries for developing ginger functional product and materials.
