Project

Delicious chips and French fries made from organic potatoes

Lead Institute OL Institute of Organic Farming

Optimizing of the organic potato production for french fries and chips

For years consumers in Germany have been consuming more and more processed potato products, such as chips or potato crisps, than fresh potatoes. But the predominant proportion of organically produced potatoes is marketed as table potatoes, so that the proportion of processed organic potato products has up to now been low. Reasons for this are the high, specific required quality demands for potato processing and a low consumer demand for table potatoes.

Background and Objective

In Germany, the acreage of organically cultivated potatoes has been about 8,000 ha for many years. So far, only a small proportion of organic potatoes is processed into chips or potato crisps. Specific varieties have to be cultivated if chips and potato crisps are to be processed. These differ significantly from the required quality criteria for those potatoes for human consumption. This is applicable to both, external (e.g., grading size) and internal quality criteria (starch content, reducing sugar content, etc.), as well as for the suitability for storage. Only through targeted, purposeful and production adapted to the specific conditions of Organic Farming can the high demands of the processing sector be fulfilled.

The aim of the project was to work out strategies for the production of high-quality processing potatoes under the conditions of Organic Farming. Therefore the focus was set on the effects of agronomic measures (choice of varieties, preceding crops, irrigation, and organic fertilisation).
