Commission on Dietetic Registration (CDR) - Provider #21328, Activity #148125 approved for 2.50 CPEUs.

CPEU Course Description

Nanomaterial engineering provides an important technological advance that offers substantial benefits for applications not only in the production and processing, but also in the packaging and storage of food.  An expanding commercialization of nanomaterials as part of the modern diet will substantially increase their oral intake worldwide as nano-sized additives may be incorporated in food to optimize properties such as taste, sensation, color, texture, and consistency.  This CPEU course focuses on data gaps and uncertainties in relevant risk assessment studies covering the dietary uptake of titanium dioxide particles.

Brooke H. Dekofsky, MPH, RD, CLE, CDE was involved in the creation of this course.
