Improving Potato Varieties

30.06.2011
Potato tubers used to manufacture potato chips and fries must meet strict quality control guidelines. One of the most important of these is a requirement that fried products are uniformly light colored after cooking.

Storing potatoes at low temperatures results in an accumulation of sugars. These sugars undergo chemical reactions during cooking that give rise to dark-colored chips and fries that may contain a high amount of a compound found in carbohydrate-rich foods cooked at high temperatures. Health concerns have been raised about the consumption of this compound, called acrylamide.

According to scientists at the Inner Mongolian University, University of Wisconsin - Madison, and the USDA Agricultural Research Service, reducing the activity of a single protein allowed for low-temperature storage of potato tubers without an accumulation of sugars. This approach was used successfully with four potato varieties currently in commercial production. The research was funded by Hatch funds to J.J. L.W. and was partially supported by the Cultivation Fund of the Key Scientific and Technical Innovation Project, Ministry of Education of China and National Key Technology R&D Program to R.F.Z.

In each case, when the targeted protein’s activity was greatly reduced, tuber quality after low temperature storage was improved. This data defines a specific genetic target for improvement of potatoes that will benefit consumers and producers by improving tuber quality and healthiness of potato products.

Furthermore, spoilage-related potato waste will likely be reduced since the modified tubers could be stored at cooler temperatures than those from conventional potato varieties.

Greenhouse and field evaluations have indicated that this method does not have negative effects on plant growth and yield. However, large-scale field trials will be necessary to validate these initial observations, according to UW-Madison scientist Jiming Jiang.

Full results from this study can be found in the 2011 May-June issue of the journal Crop Science.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
