  • 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.
  • Why is PSO important for oil peony seed production?
  • As the main by-product in the production of PSO, the weight of PSS and PSC account for more than 30% and 40% of the total weight of peony seed, respectively. And PSO is accepted by more and more consumers for the rich UFAs content and high nutritive value, the planting area of oil peony will increase up to 5 million hectares in next 5-10 years.
  • 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.
