Polyphenolic compounds with anthocyanins characteristic for coloured flesh potatoes are known for
their antioxidant properties which could improve the quality of ready products as potato chips. Five
purple potato varieties (Blaue Elise, Blaue St. Galler, Blue Congo, Valfi and Vitelotte) and four red flesh
potato varieties (Highland Burgundy Red, Herbie 26, Rosalinde, Rote Emma) were stored for nine months
and analysed for the polyphenols, anthocyanins, reducing sugars and antioxidant activity with two
different methods viz. ABTS and DPPH. After additionally in prepared potato chips oil content, texture
and colour parameters were evaluated.
