Project Type: Trust Fund Cooperative Agreement
Start Date: Jan 1, 2016
End Date: Dec 31, 2020
To assist the U.S. Potato Board in the National Fry Processing Trial by identifying potato germplasm with low reducing sugar/acrylamide accumulation potential after storage.
French fry clones submitted by cooperators will be grown at three locations and shipped to the PRW immediately after harvest. Upon receipt, the clones will be placed into 55 degrees F (95% RH) storage for two weeks. Thereafter the storages will be slowly cooled (0.5 degrees F/day) to a final temperature of 45 degrees F. After 3 and 6 months of storage, the reducing sugar content will be analyzed and a sample of each clone will be processed on the 1/20 scale french fry line as currently configured. French fry samples will be frozen, stored at -80 degrees C, and shipped on dry ice to the University of Wisconsin for acrylamide analysis.
