Red ginseng extracts accounted for the major precipitating material in red ginseng drink prepared with various components and pasteuralized at $80^{circ}C$ for 30 min. Precipitates in red ginseng extracts isolated by centrifugation were investigated for its chemical components and physicochemical properties. Recovery of precipitates in red ginseng extracts was 1.59% on a dry weight basis. Precipitates were composed of starch (71.47%), crude protein (21.75%), pectin (1.70%), polyphenol (2.97%) and calcium (3.83 ppm) but ginsenosides were not present. Absorption peak at 285 nm which appeared in red ginseng extracts was absent in the precipitates. pH and Hunter L value of the precipitates decreased, while Hunter a and b values increased in contrast to red ginseng extracts. Precipitates were solubilized to some extent in polar solvent. The shape of precipitate particle was round, sciral or irregular square. Particle size of precipitates varied from 0.17 $mu extrm{m}$ to 41.3 $mu extrm{m}$ in length.
