Development of a standardized assay for after cooking darkening by which to support cultivarselection for breeding program and timing from storage for optimum processing

The intern will work with McGill University researchers Dr. Danielle Donnelly and Dr. Stan Kubow to identify

potato cultivars with better processing quality and less inclination to form dark-colored compounds after

they have been cut (enzymatic browning) or cooked (after-cooking darkening or ACD). ACD is related to

content of certain minerals, the polyphenolic chlorogenic acid, and mediated by presence of organic acids

and possibly other antioxidants. Phytonutrients will be examined for 3 cultivars with varying ACD symptoms.

A better understanding of ACD is important to the potato processing industry.
