Guest guest Posted September 24, 2004 Report Share Posted September 24, 2004 The real problem is that most of these companies check only for really high amounts of heavy metals. Often their standard is less than 100ppm for the sum of all heavy metals. If we take a limit of 0.1ppm for Mercury, then the 100ppm are hardly sufficient. That is also true for Sheng Chang. Their final products (granules) are tested for the sum of 20ppm which also means pretty much nothing. Pesticides are not a big problem for granules. Most pesticides break down in the cooking process. We have analysed many granule batches and hardly ever find pesticides. This is very different in raw herbs. Simon Becker _____ Von: alon marcus [alonmarcus] Gesendet: Mittwoch, 22.

The buyer stays with the shipment until approval is given and then they are retested when arriving in Taiwan. The only problem is that they do not test all the batches for pesticides. They do test all batches for heavy metals. Alon Quote Link to comment Share on other sites More sharing options...
