  • 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.
  • Are peony seeds high in fatty acids?
  • Peony seeds are rich in unsaturated fatty acids (UFAs, >?90%), particularly α-linolenic acid (ALA, >?40%), much higher than that of common vegetable oils such as soybean oil and rapeseed oil [ 2, 3 ].
  • 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 ).
  • Do peony seed shells and processing methods influence the quality attributes?
  • To summarize, the present study demonstrated that the seed shells and different processing methods (CP, UAE, and SFE) influenced the quality attributes, chemical compositions, and antioxidant properties of peony seed oils. Peony seed oil was contained a high content of PUFAs and tocopherols, especially C18:3 and γ-tocopherol.
