Bacterial Counts in Ginseng Products by Dry Rehydratable Film Method

Dry rehydratable film (Petrifilm) method was compared with the standard pate count (SPC) method for estimation of total bacteria in ginseng products. Ginseng products (7 sample) was analyzed for total count by the SPC, and Petrifilm methods, respectively. In the case of ginseng tea, ginseng extract, ginseng extract pill, ginseng powder capsule, and ginseng extract tea, they showed non-significant values at the 1% level. However, the values of ginseng powder and tablet showed significant at the 1% level. These results generally indicate the suitability of the dry rehydratable film methods as alternatives to the SPC method for estimating of total bacteria in ginseng product samples except to ginseng powder and ginseng tablet.
