Pumpkin ( Cucurbita pepo L.) Seed Oil - Springer
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.
Depending on the cultivar, the cold pressed oils of unroasted pumpkin seeds have a wide range of TPC, ranging from 4.63 mg gallic acid equivalent (GAE)/kg to 2240 mg GAE/kg ( Akta et al., 2018; Vujasinovic et al., 2012 ). The phenolic compounds are responsible for the antioxidant activity of the pumpkin seed oil.
Bioactive Phytochemicals from Pumpkin Seed Oil Processing By-products
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).
In the present study, a Box–Behnken design of response surface methodology (RSM) was employed to optimize the processing factors (force: 100, 150, and 200 kN; speed: 3, 5, and 7 mm/min; and temperature: 40, 60, and 80 °C) for extracting pumpkin seeds oil under uniaxial compression. The design generated 15 experiments including twelve combinations of factors and three replicates at the

compounds found in Styrian pumpkin seed oil. Triacylglyc-erols represent the largest fraction of the oil, which also con-tains several important secondary plant components thathave been analyzed only recently. 3.1 Fatty acid composition The fatty acid pattern of Styrian pumpkin seed oil appears to be very similar to that of Styrian oil pumpkin
optimal conditions, with an average yield of 500–600 kg/ha. For the production of 1 L of Styrian pumpkin seed oil, an. average of 2.5 kg of pumpkin seeds are required, which cor-. responds to an
Chemical Composition and Oxidative Stability of Roasted and Cold
Even though they had the highest starting PV, oils obtained from the RP process of both seed varieties had the highest oxidative stability (30.3 h for naked pumpkin seed oil and 23.8 h for husked pumpkin seed oil), while the “cold pressed” oils from the the UCP process had OSI values that were the lowest (24.1 h for naked pumpkin seed oil and 19.0 h for husked pumpkin seed oil).
Cold pressed pumpkin seed oil revealed the highest γ-tocopherol content (599.33 mg kg -1 ) and the highest oxidative stability (3.84 h). However, the chloroform/methanol extracted pumpkin seed
High‐pressure‐assisted protein isolation from pumpkin seed press cake
Generally, the high-pressure treatment during protein isolation increased pumpkin seed press cake's protein yield and enhanced the isolates' techno-functional properties. Introduction In the food industry, oilseeds are most commonly used for the production of vegetable oil through pressing and/or extraction by solvents (Duodu et al ., 2018 ; Nevara et al ., 2022 ).
An important factor in the cold pressed oil manufacturing process is the temperature of the oil leaving the press. Due to friction, pressing is accompanied by the release of heat. However, modern screw presses are constructed in a way that reduces the heat released per unit mass of raw material processed by the press, thus decreasing the temperature and enabling a better temperature control
- 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 ).
- How is PSO extracted from pumpkin seeds?
- PSO is generally extracted by expelling the oil from the seeds mechanically. Both hulled and hull-less pumpkin seeds could be used for oil production. The oil from the hull-less seeds is much easier to extract and more commonly processed.
- Where does pumpkin oil come from?
- It has been produced in Slovenia, Austria, and Hungary and used as cooking oil in many parts in Africa and the Middle East. The oil content is around 50% and it can be obtained from pumpkin seeds with or without husks using solvent extraction, supercritical CO 2 or cold pressed methods.
- 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.
