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) 〔(【引用サイトリンク】title=Database Of Origin & Registration (AT/PGI/0017/1460) )〕 and the ''Štajersko prekmursko bučno olje'' (styrian prekmurjen pumpkin oil)〔(【引用サイトリンク】title=Database Of Origin & Registration (SI/PGI/0005/0418) )〕 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 layer and red in thick layer. Such optical phenomenon is called dichromatism. Pumpkin oil is one of the substances with strongest dichromatism. Its Kreft's dichromaticity index is -44. Used together with yoghurt, the colour turns to bright green and is sometimes referred to as "green-gold". ==Culinary uses== Pumpkin seed oil has an intense nutty taste and is rich in polyunsaturated fatty acids. Browned oil has a bitter taste. Pumpkin seed oil serves as a salad dressing when combined with honey or olive oil. The typical Styrian dressing consists of pumpkin seed oil and cider vinegar. The oil is also used for desserts, giving ordinary vanilla ice cream a nutty taste. It is considered a real delicacy in Austria and Slovenia, and few drops are added to pumpkin soup and other local dishes. Using it as a cooking oil, however, destroys its essential fatty acids.〔(【引用サイトリンク】title=The Benefits of Pumpkin Seeds )〕〔(【引用サイトリンク】title=Healthy Cooking Oils )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pumpkin seed oil」の詳細全文を読む スポンサード リンク
