  • What is the oil yield of peony seeds?
  • For shelled peony seed, the oil yield was in the range of 24.22?30.7%, and for non-shelled peony seed, the yield was low. 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 ).
  • What is peony seeds oil?
  • Peony seeds oil (PSO) was approved as a new resource food and became an edible vegetable oil for its rich content of fatty acids, total unsaturated fatty acids, linoleic acid and linolenic acid. In addition, PSO also contains high contents of squalene, tocopherol, phytosterol and plant polyphenol.
  • How to extract peony Seed Oil (PSO)?
  • A variety of methods has been applied to extract peony seed oil (PSO), which includes expeller pressing, organic solvent extraction, microwave-assisted extraction, ultrasonic-assisted extraction, and supercritical carbon dioxide-assisted extraction [ 6 ? 9 ].
  • Are peony seeds a waste?
  • However, almost all the peony seeds have been just taken as industrial waste. During the newly past decade, this plant resource is attracting great interests for further development since peony seeds, especially the seeds' oil, have been found rich in unsaturated fatty acids, amino acids, stilbenoids, and other nutrient substances [ 4, 5 ].
