  • What technology is used to extract Camellia seed oil?
  • Mechanical pressing extraction (MPE) and solvent extraction (SE) are now the dominant technologies used for the industrial-scale extraction of camellia seed oil, owing to advantages such as low capital investment and easy operation .
  • How does the extraction process affect the nutritional quality of camellia seed oils?
  • In conclusion, the extraction process can affect the nutritional quality of camellia seed oils in different ways. First, the extraction process might change the type and content of active substances in crude camellia seed oil. Secondly, crude camellia seed oils are subjected to different refining processes depending on their quality.
  • How to improve the yield and quality of camellia seed oil?
  • Suitable pretreatment procedures are usually needed to improve the yield and quality of camellia seed oil. The major pretreatment steps include cleaning, deshelling, dehulling, drying, and size reduction (grinding, crushing, and so on) (Figure 2).
  • Does Ultrasound-assisted solvent extraction improve camellia seed oil extraction efficiency?
  • The camellia seed oil extraction efficiency of ultrasound-assisted solvent extraction (UA-SE) was 7.08% higher than that of traditional SE , while the extraction time decreased from 90 min to 30 min, process temperature decreased from 60 °C to 40 °C, and solvent-to-sample ratio decreased from 7:1 to 6:1.
  • Is MPE suitable for camellia seed oil extraction?
  • MPE is suitable for extraction from seeds with high oil contents (>25%) . Nowadays, MPE accounts for the largest market share among the processes used for camellia seed oil extraction in China . However, MPE is often hampered by low oil yield, and certain amounts of oils are left in the pressed cakes.
  • What is a good extraction pressure for camellia oil?
  • The typical range of extraction pressure for camellia oil is 30–40 MPa, which can facilitate the extraction of constituents under different bound states [11, 68, 120, 121]. High extraction temperatures are preferred for enhanced mass transfer and dispersion, but they reduce the density and dissolving capacity of fluids.
