Can a model be used to optimize oil extraction from peony seeds?
Therefore, the model was considered to be available for optimizing the process of oil extraction from peony seeds. The oil yield of peony seeds was significantly influenced by the maturity period (Table 4 ).
How is peony seed oil extracted?
Peony seed oil was achieved using a Waters SFE 100 CO 2 extraction system (Waters, Corp., Milford, MA, UK). 100 g of shelled and de-shelled peony seed powder was filled into a 2 L extraction vessel. The supercritical carrier was carbon dioxide (SC-CO 2, 99.999% purity).
Can peony seed kernel and Shell Oil be extracted?
The study detected and compared the quality, lipid characteristics, and antioxidant activities of peony seed kernel and shell oil using three extraction techniques (cold pressing, supercritical fluid extraction, and ultrasonic-assisted solvent extraction).
Do different extraction methods affect free radical scavenging capacity of peony seeds?
Meanwhile, a significant difference ( p <0.05) in antioxidant activity between tested seed oils indicated that different extraction methods influenced the free radical scavenging capacity of peony seed kernel and shell oils.
