Description
Pumpkin seed oil (Kernöl or Kürbiskernöl in German, bučno olje in Slovenian, bučino ulje in Croatian, tikvino ulje or bundevino ulje in Serbian, ulei de dovleac in Romanian, and tökmag-olaj in Hungarian), is a culinary specialty from what used to be part of the Austro-Hungarian Empire and is now southeastern Austria (Styria), eastern Slovenia (Styria and Prekmurje), Central Transylvania, Orăștie-Cugir region of Romania, north western Croatia (esp. Međimurje), and adjacent regions of Hungary. The Steirisches Kürbiskernöl (styrian pumpkin seed oil) and the Štajersko prekmursko bučno olje (styrian prekmurjen pumpkin oil) are European Union Protected Designation of Origin (PDO) products.
The oil is an important export commodity of Austria and Slovenia. It is made by pressing roasted, hulled pumpkin seeds (pepitas), from a local variety of pumpkin, the “Styrian oil pumpkin” (Cucurbita pepo subsp. pepo var. ‘styriaca’, also known as var. oleifera). It has been produced and used in Styria’s southern parts at least since the 18th century. The earliest confirmed record of oil pumpkin seeds in Styria (from the estate of a farmer in Gleinstätten) dates to February 18, 1697. The viscous oil is light to very dark green to dark red in colour depending on the thickness of the observed sample. The oil appears green in thin layers and red in thick layers, an optical phenomenon called dichromatism. Pumpkin oil is one of the substances with the strongest dichromatism. Its Kreft’s dichromaticity index is -44. When used together with yoghurt, the oil turns bright green and is sometimes referred to as “green-gold”.
Seed types and oil Other types of pumpkin seed oil are also marketed worldwide. International producers use white seeds with shells and this produces a cheaper white oil. New producers of seeds are located in China.
