What technologies are used in the extraction of 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 [ 11 ].
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 is camellia seed oil produced?
In this process, camellia seed oil is obtained through a combination of MPE and SE, which provides an overall oil yield in excess of 95% [ 51, 78 ]. Hexane and No. 6 solvent are the most commonly used organic solvents in camellia seed oil production [ 13, 80 ].
What are the uses of camellia seed cakes?
After oil extraction, the residual seed cakes can be used as raw materials for preparing animal feeds, organic fertilizers, and biotic pesticides [ 6 ]. Camellia seed oil is known as “oriental olive oil” because its fatty acid profile is similar to that of olive oil.
