Recovery of rosehip seed oil from food industry waste was performed by scCO2 extraction.
Solubility of rosehip oil was the rate-limiting step for oil recovery from waste oilseeds.
Changes in morphological structures of the seeds were determined via SEM.
The compositions of rosehip seed oil extracted by different methods were very similar.
Oil solubility values in scCO2 exhibited substantial consistency with empirical models.
