  • What is the extraction efficiency of pine nut oil?
  • The extraction efficiency of pine nut oil ranged from 65.12 to 90.68% depending on the solvent extraction conditions ( Table 2 ). The maximum extraction efficiency corresponded to extraction of pine nut oil at 45 °C for 60 min with S/S ratio of 20:1 mL g −1.‌
  • What are the optimum conditions for the production of pine nut oil?
  • The optimum conditions for the production of pine nut oil with solvent extraction were attained at the extraction temperature of 39.3 °C, extraction time of 33.4 min and S/S ratio of 10.8:1 (mL g −1 ).‌
  • How stable is pine nut oil?
  • PV value of pine nut oil samples ranged from 0.80 to 3.65 meq peroxide kg −1 oil depending on the extraction conditions ( Table 2 ). These results indicated that pine nut oils obtained at all the extraction conditions were very stable in which oils with PV < 20 are very stable and regarded as very good quality ( Pike & O'Keefe, 2017 ).‌
  • Do solvent extraction conditions affect physicochemical properties of pine nut oil?
  • Pine nut oils obtained at all the extraction conditions were stable and in good quality. Effects of solvent extraction conditions on the extraction efficiency, physicochemical properties and antioxidant activity of pine nut oil were investigated and optimized by using three level Box-Behnken design (BBD).‌
  • How to extract oil from pulverized pine nuts?
  • Sub-critical extraction: The oil from approximately 200 g of pulverized pine nuts was extracted using sub-critical extraction apparatus CBE-5L (Henan Sub-critical Biotechnology Co. Ltd., Anyang, China). The extraction conditions were as follows: extraction solvent, n -butane; flow rate, 77 L/h; extraction pressure, 0.5 MPa; temperature, (21± 5) °C.‌
  • Which solvent is best for extracting pine nut oil?
  • N-hexane was found to be the most effective solvent for the extraction. Extraction efficiency, physicochemical properties and antioxidant activity of pine nut oil were highly affected by temperature, time and S/S ratio. Desirability function approach was used to determine optimum conditions.
