How many tests for quality, purity, potency, and freshness are performed on the raw materialst?
Depending on the material, approximately 4-5 tests are performed on raw materials. Initially, raw biological materials are quarantined in a separate facility until microbiological assays for yeasts, molds, E. Coli, Salmonella, and bacteria are all negative. On average, about 30% of raw materials are rejected routinely because they do not meet the required standards. Then the materials are “ID’ed” or identified as being what they claim to be. This identification is done through High Pressure Liquid Chromatography (HPLC) and Inductively Coupled Plasma Emissions Spectrometry (ICP). These tests result in a biological signature for the tested compound, which is then compared to known biological signatures for the desired compound.
