  • 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.
  • Is peony seed oil a stable oil-in-water microemulsion?
  • Peony seed oil (PSO) is an edible oil with high nutritional value. In this study, a stable oil-in-water microemulsion (Blank-ME) was prepared using PSO as the oil phase, and RH 60-CO 40-Span 80-PEG 200 (RCSP) as surfactants and co-surfactants.
  • 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.
  • 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 ).
