The investigations in 2006 showed that the anthocyanin content has an influence on the<br />

antioxidant capacity and therefore on the health promoting effects. Anthocyanin content and<br />

antioxidant capacity are dependent on type and according to the results from 2006 are not influenced<br />

by the use of a nitrogen fertiliser or the cultivation system (organic/integrated). The results regarding<br />

to anthocyanin content and antioxidative capacity showed no increasing or decreasing effect<br />

concerning to the different cultivation systems. Differences in the level of both values depend on the<br />

potato varieties and/or on prevailing stressors like heat and aridity.<br />

Some of the tested varieties showed disadvantageous concerning to skin texture, shape or<br />

taste. Especially Red Cardinal and Vitelotte showed an unfavorable skin texture with deep eyes. These<br />

varieties can only be used as potatoes with skin because the peeling losses would be too high.<br />

Conclusions<br />

Blue potatoes are cultivated only in very small quantities in Germany at the moment, but<br />

varieties and yield are not documented. The results of the research project show that it is possible to<br />

cultivate particular type’s e.g. old anthocyanin containing types of potatoes in organic and integrated<br />

farming; however a breeding process must take place concerning the needs of the user today regarding<br />

skin texture, shape or taste. The additional health benefits of food are brought more and more to the<br />

attention of the public. In addition a positive influence on biodiversity can be expected in the<br />

agricultural sector.<br />
