  • How to extract peony seeds?
  • Peony seeds → Deshelling → Grinding → Sieving (40 meshes) → +Water → Adjust pH value and temperature → Enzymolysis → Extinguishing enzyme → Centrifuge separation → Drying → PSO. Aqueous enzymatic extraction conditions were optimized at pH 7.5, enzymolysis temperature 50 ℃, the amount of alkaline protease 2.5% (enzyme/seed ·dry mass) for 300 min.
  • What is the extraction rate of peony seeds?
  • When the peony seeds were pretreated by microwave, the extraction rate of PSO by SFE-CO 2 could reach 98.55%, and only 1.45% of the oil remained in the cake (Lu, Tan, Hao, & Wu, 2015). The content of total UFAs in PSO was 70.81–92.3%, in which ALA was 32.38–66.95% and LA was 17.95–34.90% (Table 4).
  • Does peony seed particle size affect oil yield?
  • The peony seed particle size (20–60 meshes) on the oil yield of PSO was studied by Wang, Zhang, and Dong (2009), and the results suggested that the extraction rate increased significantly when the particle size of peony seed reached 40 meshes, while the extraction rate decreased when the particle size reached 60 meshes.
  • How many species of oil tree peony are there?
  • The genus Paeonia includes about 35 species in the world, widely distributed in temperate regions of Europe and Asia. There are 17 species in China, and 9 of which belong to section Moutan DC. Oil tree peony are deciduous shrubs.
  • What are the pretreatment conditions for peony seed powder?
  • Microwave pretreatment conditions were optimized at microwave pretreatment time 40 s, particle size of peony seed powder 100 meshes, moisture content of peony seed 6.2%. Influence order: moisture content > pretreatment time > particle size. And extraction conditions were optimized at 33 MPa, 40 °C, 100 min. The PSO extraction rate was 98.55%.
  • What is the PSO yield of peony seeds?
  • The PSO yield was 19.08%. Peony seeds → Grinding → Sieving→+Water → Ultrasonic treatment → Temperature and pH adjustment → Enzymolysis → extinguishing enzyme → Centrifuge separation → Drying → PSO.
