In 2010, export of table grapes from India suffered an economic blow
when a plant growth retardant, chlormequat chloride, was detected.
The issue necessitated expansion of the residue control program to
cover all agrochemicals registered for usage in agriculture and public
health managements. Banerjee’s team expanded the scope of the
multiresidue method by covering more than 200 chemicals for regular
monitoring in each consignment of fresh grapes and other fruits and
vegetables for export. Similar residue monitoring and control programs
are also being implemented in other agricultural commodities and for
the domestic market. Banerjee will explain development of residue
methods for complex matrices (e.g., tobacco, spices, chicken meat, and
fatty fish) for the analysis of pesticides, persistent organic pollutants,
mycotoxins, antibiotics, and drug residues.
During the Wiley Award Address, Banerjee will highlight efforts
undertaken since 2010 to develop effective methods for typically
problematic, single-residue compounds, which mostly include plant
hormones and herbicides whose maximum residue limits are set at
the default level of 0.01 mg/kg. The endeavor is to support industry
in dealing with food safety issues related to these emerging food
contaminants. Furthermore, Banerjee will showcase how use of
advanced column chemistry, HILIC chromatography, and strategic
sample preparation steps, including selective cleanups, can help
resolve specific analytical problems for such polar compounds.
Banerjee will also cover his recent research, which focuses on
applications of high-resolution mass spectrometry (HRMS), using
advanced features of quadrupole-TOF and orbitrap MS in combination
with ultra-performance LC. Nontarget screening is highly relevant
for screening of post-harvest food samples where the history of
agrochemical applications is not available and there are possibilities
of detection of pesticides originating from indirect sources. Accurate
MS-based screening in combination with selected reaction monitoring-
based quantifications can also simultaneously nullify matrix effects
and ensure accurate identification and quantification of residues.
HRMS workflows have been developed for residue analysis in complex
spice matrices, which could resolve several issues of false detections.
In addition to the highly sensitive, large-scale, multiple reaction
monitoring-based workflows, he will touch upon advanced technologies,
e.g., multidimensional and comprehensive two-dimensional
chromatography, low-pressure GC-MS, among others. In conclusion,
he will present his recent research focus on HRMS-based metabolomic
profiling of fruits and vegetables to explore their bioactivity and
characterization as nutraceutical products.

ABOUT KAUSHIK BANERJEE
Dr. Kaushik Banerjee
is an Indian chemist
who helped build India’s modern analytical
testing program for pesticide residues and
other contaminants in foods. He has worked
for more than 2 decades for the Indian Council
of Agricultural Research’s National Research
Center for Grapes, and heads the National
Referral Laboratory on Agrochemical Residues.
In this position, he also helped to build a
network of accredited laboratories in India,
as well as organizing proficiency testing and
inspections to verify quality control.
Banerjee was a member of the AOAC
expert review panel that evaluated
methods for pesticide residue analysis for
The Coca-Cola Company and Pepsi project.
He regularly participates in AOAC’s Annual
Meetings, contributes to the
Journal of AOAC
INTERNATIONAL
(contributing papers, editing
special sections, and more recently serving as
a member of the Editorial Board). He served as
president-elect of the AOAC India Section, and
as president since 2014. He has edited a special
section of
J. AOAC Int.
based on work presented
at the 2015 annual conference of the India
Section.
Banerjee is recognized for his accomplishments
in administration and international
harmonization. In addition to the Harvey W. Wiley
Award, he was named a Fellow of Britain’s Royal
Society of Chemistry in 2011 for his research
accomplishments.
He has published more than 60 papers in the
past decade on analytical method development
and validation. The papers have covered a wide
variety of food-related topics, including GC/MS
and LC/MS detection of pesticides, antibiotics,
and other organic chemicals in foods ranging
from grapes, pomegranates, and mangos to
okra, fish, and peanuts.
Banerjee attended graduate school at the Indian
Agricultural Research Institute in New Delhi,
where his specialty focused on agricultural
chemistry.
