University of Wisconsin-Madison researchers have been selected to lead a national, multi-institution effort to improve the quality and safety of processed potatoes, the USDA's National Institute of Food and Agriculture (NIFA) announced in October.

The $3.7 million Specialty Crop Research Initiative grant will support an effort to reduce the amount of acrylamide in french fries and potato chips, without sacrificing the taste and texture that make these products so popular with consumers.

The project was developed with major input from key stakeholders in the fresh, frozen processed and chip potato industries representing all major potato growing areas in the United States. Over 30 representatives from these sectors and the end-user community make up the project's advisory committee, including growers, processors, major food vendors such as McDonald's, the U.S. Potato Board and the National Potato Council.

The grant will involve scientists from 10 universities and USDA labs from around the nation who will work to develop potatoes that produce less acrylamide when they are cooked. This involves searching for varieties with low levels of reducing sugars and the amino acid asparagine, which combine to produce acrylamide when potatoes-like other starchy foods-are fried at high temperatures. They will also hunt for helpful molecular markers to use in breeding new varieties. Industry partners will grow, store and cook the potatoes and assess their key traits.

The goal of the four-year project is to provide the industry with four new chip potato and four new fry potato lines that yield chips, fries and similar products that have reduced acrylamide levels and meet with consumer approval.
