in ochratoxin A (OTA) analysis:
structure of Ochratoxin A (OTA)
can undertake ochratoxin A (OTA) analysis from coffee and cocoa using
the most sensitive methods available. This involves the use of immuno-affinity
columns to purify the OTA, and high perfomance liquid chromatograph (HPLC)
with fluorescence detection for quantification.
These are similar
to UKAS accredited methods. Additionally, fungi isolated from coffee can
be analysed for OTA production using similar and/or screening procedures.
In-country training can be provided, as can methods that are more suited
to developing countries.
can offer advice on an HACCP approach in reducing OTA from field to consumer.
Furthermore, a rapid method for determining the total fungal biomass on
coffee and cocoa called ergosterol analysis can be undertaken, as can
the analysis of other mycotoxins if these are considered to be a potential
