Cold pressed pumpkin seed oil
The cold pressed pumpkin seed oil belongs to the oleic-linoleic acid group oils including corn, sesame, sunflower, soya, and cottonseed oils (Baolu, 2014). The proximate fatty acid composition of the cold pressed pumpkin seed oil is summarized in Table 1. The main fatty acids of the oil are linoleic, oleic, palmitic, and stearic acids.
The nutritional value of pumpkin seeds is based on high protein content (25–51%) (Bombardelli and Morazzoni 1997) and high percentage of oil that ranging from 40% to 60.8% (Fokou et al. 2009; Achu et al. 2006 ). The variability in the oil content of pumpkin seed is due to its broad genetic diversity.
Production technology and characteristics of Styrian pumpkin
the production of pumpkin seed oil representing a current market value of more than 30 million Euros. In the year of 2006, approximately 20% of the oil was exported, with Ger-many being the main importing country followed by other European Union members and the USA. 3 Composition of Styrian pumpkin seed oil

The most important bioactive components of cold pressed oil
The impact of the extraction method on physicochemical parameters, fatty acids, bioactive compounds, and oxidative stability of the obtained pumpkin seed oil was assessed. Pumpkin seed oil was rich in unsaturated fatty acids (>80%), squalene (174.1–253.6 mg/100 g), β-sitosterol (147.7–208.2 mg/100 g), and tocopherols (53.1–73.3 mg/100 g).
In the production of pumpkin seed oil, ground pumpkin seeds are mixed with water and salt to form a dough which is then roasted at 110-150 C and pressed [1]. Due to the low yield of oil
Bioactive Phytochemicals from Pumpkin Seed Oil-Processing By
The carbohydrate level of all cookies with hull-less pumpkin seed oil press-cake flour was much lower than that of brown rice and whole-wheat flour cookies (9.5–36.8%). With the addition of hull-less pumpkin seed oil press-cake flour (PCF), the protein content of samples 1 and 4 increased significantly (10–40% of added PCF).
popularity of ‘‘cold pressed oils’’, pumpkin seed oil pro- duced from raw, unroasted seeds and declared as ‘‘cold pressed’’ is appearing on grocery shelves [12].
Changes in chemical composition of pumpkin seeds during the
Pumpkin (Cucurbita pepo L.) seed oil is a special product of the southern Austrian region.For the production of the oil, prior to the pressing procedure, the seeds are roasted at temperatures up to 130 °C, which leads to the formation of the typical roasty and nutty aroma.
The valuable lipids in the pumpkin seeds are transferred directly into this deep green oil when it is cold-pressed by Pdr. It might be interesting to know that for Styrian pumpkin seed oil Pdr needs around 30 pumpkins or 2.5 kg of pumpkin seeds per liter of oil. Uses for cold-pressed Styrian pumpkin seed oil Ingredients.
- What is cold pressed pumpkin seed oil?
- According to the Codex Alimentarius, cold pressed pumpkin seed oil is directly obtained from raw and dried seeds using a continuous screw press ( Codex Alimentarius, 1999 ). The outlet temperature of the oil should be kept below 50°C for the oil to be labeled as cold pressed pumpkin seed oil ( Vujasinovic et al., 2010 ).
- Does cold pressed pumpkin seed oil contain fatty acids?
- In summary, cold pressed pumpkin seed oils have lower acid and peroxide values than the maximum limits (4 mg KOH/g oil and 15 meq O 2 /kg oil, respectively) set by the Codex Alimentarius ( Codex Alimentarius, 1999 ). The formation of free fatty acids may be associated with the hydrolysis of triacylglycerols prior to pressing.
- Does cold pressed pumpkin seed oil contain lignans?
- In Latvia, the presence of sesamolin (7.17 mg/100 g in 2011 and 2.49 mg/100 g in 2012) and sesamin (20.54 mg/100 g in 2011 and 7.22 mg/100 g in 2012) lignans in cold pressed pumpkin seed oil were revealed ( Górna, Siger, Pugajeva, & Seglia, 2014 ). These results indicated the improper and inadequate cleaning procedures carried out in plants.
- Which volatile compounds are found in cold pressed oil of pumpkin seeds?
- The principal volatile compounds identified in cold pressed oil of unroasted pumpkin seeds are hexanol, 1-pentanol, hexanal, 3-methylbutanal, 2-methylbutanal, pentanal, and benzaldehyde ( Potonik & Koir, 2017 ).
