NanoRelease Food AdditiveSupporting Methods to Measure Food Nanomaterials
Webinar to present Task Group White PapersApril 16 , 2013

What is the issue being addressed?
2www.riskscience.org
Nanopowder
Dissolved constituents (no longer nano?)
Engineered nanomaterials (ENM) used/being developed for food, beverages, supplements to:- increase nutrition- increase food safety (packaging, shelf life)- change physical/chemical properties
Some “traditional” processed food components are nano too. Where do we focus the science to address potential risk?
Methods to measure what nano characteristics affect absorption as nanoparticles into the body would greatly clarify where to focus attention.
About the project
OFFICIAL CHARGE: “Identify, evaluate, and develop methods needed to confidently detect, characterize and evaluate intentionally produced nanoparticles released from food along the alimentary tract, as occurring through direct food additives or indirect incorporation in food through migration from food contact materials or environmental contamination.”

• 70+ multi-stakeholder experts collaborating for methods development for oral exposure to ENM
• GOAL: Develop methods that distinguish which nanomaterials do and do not persist to absorption from food.
thus provide data that help clarify risk thus allow safer, sustainable improvements
Benefits of the project• Continuous technical dialogue internationally across
key stakeholder experts about safe development of food nanotech
• Public-private partnership allows balance of views from academia, industry, government, public interest organizations
• Secretariat (ILSI Research Foundation) facilitates collaboration without backing any particular stakeholder view.

PROJECTWEBINAR
SOSTState of the Science Team is an experienced, balanced multi-
stakeholder set of experts who are writing a “state of the science” report on: What do we know and need to know to measure and understand the likelihood of nanomaterial uptake by the body?

ITGINTERLABORATORY TESTING GROUP
• Lab research experts currently being gathered
• OBJECTIVE: Develop or investigate standardization of existing methodologies (adaptation and validation) with any necessary modifications
• Interlaboratory work plans will improve/develop methods for understanding uptake, using (-) and (+) controls and selected ENM in modeled GI conditions
• ULTIMATE GOAL: promote standardization or scientific consensus on practical methods for evaluating potential uptake of ENM from alimentary canal

Goal for this webinar• Present high point findings of
the task groups
• Inform the State of the Science team as they prepare their summary
• Seek input from stakeholders
• Inform the Steering Committee as they select methods to carry forward

Suggested topics for feedbackPlease note that the project goal is to GOAL: Develop methods that distinguish which nanomaterials do and do not persist to absorption from food.
thus provide data that help clarify risk thus allow safer, sustainable improvements
For example, please help us inform the Steering Committee in their task to - Cover what needs to be covered to prepare to address this goal- Narrow scope to practical and near-term methods improvement- Select methods improvements to address- Identify how to improve the methods- Identify synergies and partnerships
