  • What is oil-seed camellia?
  • 1. Introduction The oil-seed camellia (Camellia oleifera Abel) joins olives, palms, and coconuts as one of the four major woody oil crops globally, and is primarily distributed in China, India, Japan, and Southeast Asia (Gao et al., 2024). The oil extracted from its seeds, commonly known as tea seed oil (TSO).
  • How are camellia seeds pressed?
  • Cold-pressed: The camellia oils were obtained by pressing the dried camellia seeds at 60 °C. Roast-pressed: The camellia oils were obtained by pressing the dried camellia seeds at 120–130 °C. Fresh-pressed: The freshly picked camellia seeds were pressed immediately. Then, the camellia oils were obtained by centrifugation.
  • How are camellia oils processed?
  • In this study, camellia oils were obtained using four different processing techniques (cold-pressed, roast-pressed, fresh-pressed, and refined), and their triacylglycerols (TAGs) profile, bioactive compound (tocopherols, sterols, squalene, and polyphenols) level, oxidative stability, and volatile compounds were analyzed and compared.
  • What is the difference between pressed and refined camellia oil?
  • In particular, it was observed that pressed camellia oil exhibited unique molecular TAGs (LLLn, LLnLn, and PPLn), while refined camellia oil showed distinctive PLLn and PLnLn. These characteristic TAGs with low content have the potential to distinguish between different processing techniques of camellia oils.
  • How to produce camellia oil in industrial applications?
  • Despite the success of the aqueous enzymatic and supercritical extraction in the laboratory, the mechanical pressing and commercial refinement are still the most widely used techniques for producing camellia oil in the industrial applications owing to their easy operation, high efficiency, and low cost [12, 13].
  • Does processing technique affect camellia oil quality?
  • This study provided a comprehensive comparative perspective for revealing the significant influence of the processing technique on the camellia oil quality and its significance for producing camellia oil of high quality and with high nutritional value.
