  • 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.
  • 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 are the by-products of peony seeds production?
  • In the process of PSO production, two important by-products, peony seeds shell (PSS) and peony seeds cake (PSC) will be obtained. The total mass of PSS and PSC accounts for more than 70% of the total mass of peony seeds ( Deng et al., 2019 ).
  • How much PSO is produced from peony seeds?
  • Based on the output of 3.75 tons/ha of peony seeds ( Liu et al., 2018b ), five million ha of oil peony will produce more than 5625 thousand tons of PSS and 7500 thousand tons of PSC during the process of PSO production. It will be a great waste of natural resources if these by-products can not be reasonably utilized.
