Adulteration, impurities found in green coffee bean extracts

Adulteration, impurities found in green coffee bean extracts

Chemical profile results reveal a pervasive market presence of questionable green coffee bean extracts with inconsistent total chlorogenic acid.

Green coffee bean extract has become extremely popular due to recent attention in the media. Because of numerous inquiries, FutureCeuticals recently undertook an in-depth examination of various widely available, suspiciously inexpensive "green coffee bean" extracts. Chemical profile results reveal a pervasive market presence of questionable green coffee bean extracts with inconsistent total chlorogenic acid (CGA) levels across testing methods and disproportionate representative levels of the various natural chlorogenic acid moieties typically found in green coffee beans. These results, in conjunction with non-compliant FTIR identity testing results, strongly suggest adulteration with cheaper, non-green coffee bean sources of chlorogenic acid.

Questions to ask:

  • Does your supplier test CGA by HPLC in addition to, or instead of, UV? HPLC allows for a more comprehensive profile of the various CGA moieties in the extract for a more accurate comparison with typical green coffee bean CGA profiles.
  • Does your supplier have a complete knowledge of the material that they are selling? Can they confidently say that their product is 100% pure green coffee bean extract? If so, where is their proof?
