  • In order to shorten the extraction time of saponin in ginseng products, election with Extrelut column and phase-separation methods were compared. The results obtained are as follows. 1. Saponin of ginseng products was extracted completely within 3 hours by election method with Extrelut column, and the rate of removing glucose by the column was increased with increasing glucose content in ginseng products. 2. Stirring method was superior to refluxing method for removing sugars from ginseng products, and removing rate was deceased in the order of lactose, sucrose and glucose. 3. Extraction rate of ginsenoside from ginseng extracts by the elution method was nearly same as that of phase-separation method; however, the former was much higher than the latter in the case of ginseng teas. Therefore, the elution by Extrelut column is to be improper for extraction of saponin in ginseng tea which contains much sugar. It was necessary to remove lipophilic compounds for extraction of saponin from ginseng extracts by elution with Extrelut column.

  • A study was designed to study the sorption characteristics of powder-type products of red ginseng such as red ginseng tea, red ginseng powder and spray 4ried powder of red ginseng extract The sorption rates and equilibrium moisture contents on these products were calculated at ova. a range of relative himidities and two different temperatures ($25^{\circ}C$ and 38$^{\circ}C$). Significant differences between these three products were found in water activities, sorption rates and the relationship between the ratio of %H2O/RH and moisture content The red ginseng tea required the most excessive drying to reach aw=0.4, followed by red ginseng power and spray dried powder of red ginseng extract Attempt was made to obtain equations which can predict sorption rate and moisture content of red ginseng products at given relative humidity and temperature after certain period of storage.
