Tea seed oil
Tea seed oil(also known ascamellia oil,camellia seed oil,teanut oil) is an edible plant oil. It is obtained from the seeds ofCamellia oleifera.
Camellia sasanquais also given as a source of 'tea seed oil.[1]
Description
[edit]The genusCamelliaincludes several commercially important species -Camellia oleiferais grown mainly in China forvegetable oil.[2]The oil is known as 'camellia oil', 'tea seed oil', or 'camellia seed oil'.[2]As of 2016 4,000,000 hectares (9,900,000 acres) ofoleiferaforest centered on theYangtzeriver basin inHunan,Jiangxi,andGuangxiproduces 0.26 million tons of oil.[2]
WildCamellia oleiferacontains ~47% oil, whilst cultivated varieties have shown oil content from 42 to 53%.[3]Oil analysis of cultivated varieties showed: ~76-82%oleic acid;5-11%linoleic acid;7.5-10%palmitic acid;1.5-3%stearic acid- the ratios are similar to that found in wildoleifera.[3]The composition is similar to that ofOlive oil.[2]Another analysis of several cultivars found: 82-84% unsaturated acids of which 68-77% oleic acid; and 7-14% polyunsaturated acids.[4]
Uses
[edit]With its highsmoke pointof 252 °C (486 °F),[5]tea seed oil is the maincooking oilin some of the southern provinces ofPeople's Republic of China,such asHunan,especially in mountainous regions; roughly one-seventh of the country's population.
Cautions
[edit]Tea seed oil should not be mistaken fortea tree oil(melaleuca oil), an inedibleessential oilextracted from the leaves of the paperbark,Melaleuca alternifolia,which is used for medicinal purposes.
