Changes in Physicochemical Compounds with Heating Treatment of Ginseng

摘要

Response surface methodology was used for monitoring changes in physicochemical properties with heating condition of ginseng which was sliced and freeze-dried. As heating temperature and time increased, soluble solid content decreased and browning color increased. Also, acidic polysaccharide and total phenolics increased with the increase in heating temperature and time. Heating condition for maximum soluble solid content was 146.05°C in heating temperature and 18.16 min in heating time. Maximum value of crude saponin content was 64.40 mg/g in 160.00°C and 20.00 min. Crude saponin content was influenced by heating time but the other properties were influenced by heating temperature.
