New Blood 2017: Developing Methods for the Detection of
Chemical Residues, Contaminants and Important Analytes
The detection of chemical analytes, residues, and contaminants
in consumer commodities and the environment is an interesting,
challenging, and continually evolving discipline. In order to maintain a
vibrant and active Chemical Contaminants community in AOAC, young
scientists must be encouraged to work in these areas. The purpose of
this session is to provide new members of our community an opportunity
to present their work for the first time at a technical session at the
AOAC Annual Meeting. The presentations in this session represent
the broad interests of the AOAC Chemical Contaminants Community
that emphasize the analysis of pesticide and veterinary drug residues,
environmental and industrial contaminants, adulterants, natural toxins,
and other important chemicals or issues in food, feed, environmental
samples and other relevant matrices. It is hopeful to continue the
tradition to have a New Blood session at every AOAC meeting dedicated
to new and talented AOAC scientists, stakeholders, and members.

Challenges in Food Allergen Management: Effective Tools
and Practical Considerations
Food allergen management is a difficult task for the food industry
and all other stakeholders involved. Regulations are very diverse with
few regulated thresholds, making it challenging to interpret results
“correctly”. Test kit manufacturers aim to develop analytical methods
that meet the demands of the food industry. As this industry has diverse
needs, a one-for-all solution is not achievable. On the other hand,
academic research is focusing on food allergen mass spectrometry
methods which are typically not suitable for the inevitable in-process
testing in food production environments.
This session will link these different aspects of food allergen
management and explain the challenges each party faces. An overview
about the history of allergen legislation sheds light on the different
regulations that apply and why it is so difficult to find common and
detailed rules. The lack of allergen threshold levels is not only a
challenge for the food industry, but also for test kit manufacturers who
need to ensure that their testing solutions are compatible with the
indefinite range of applications. Close cooperation between the food
producer and the test kit supplier is crucial to achieve the required high
level of food safety. Specific demands and real-life experiences from
the food industry’s perspective will also be part of the discussion, as
well as the latest results of the iFAAM ring trial that give an overview of
the current capabilities of analytical methods. The discussion will also
cover the advantages and disadvantages of immunological and mass
spectrometry based methods and give an outlook of considerations for
future approaches.

Practical Considerations about Food Allergen Testing from
an Industry Perspective
Characterization of Botanical Extracts Using
Multiple Technologies
Most commercially available Botanical Reference Materials (BRMs)
used for identity testing are botanicals in their original form (leaf,
root, seed, etc.). This can present problems when BRMs are used to
verify the identity of botanical extracts, which may or may not have a
similar profile to the unprocessed botanical. For proper identification of
botanical extracts, Botanical Extract Reference Standards are needed.
Whereas powdered botanicals typically retain most of the chemical
constituents found in the original plant material due to light processing
(e.g., grinding), botanical extracts undergo complex and vigorous
processing (such as solvent extraction, fractionation, distillation,
fermentation, addition of excipients, etc.) which can cause significant
changes in the chemical profile. Scientists tasked with verifying the
identity of botanical extracts must understand how processing steps
can affect the composition of an extract reference material, as well
as understand which reference materials are appropriate for use for
each sample.
This session is intended to cover the important considerations for
characterization of botanical extracts by assessing their unique
profiles. Various technologies are available for characterization of
the chemical components in botanical extracts, including HPTLC and
HPLC checking the chromatographic profile with separation, and NMR
analyzing the spectroscopic profile, LC-MS combining the physical
separation capabilities of liquid chromatography with the mass analysis
capabilities of mass spectrometry.
All these considerations need to be addressing during full
characterization of botanical extracts with different technologies. This
session proposes to cover this topic by scientists with expertise in
different techniques.
