摘要

A claim of a camellia oil healthcare benefits as a result of the high amount of 'tea polyphenol' arises a widely discussion in China currently. A laboratory solvent extracted crude oil (SECO) and a commercial cold pressed oil (CPO) were used for evaluation of oil attributes, particularly, total phenol content (TP). Effects of different solvents on phenol extraction for phenol profile were also investigated. According to GB 11765 (a Chinese standard for camellia oil quality), acid value (AV), peroxide value (PV), sensory attributes, i.e. transparency, odour and flavour of CPO met the requirements, while SECO showed turbid. TP in SECO had no significant difference compared with that in CPO, thus, the phenol profile of SECO seemed to be more complicated in comparison with that of CPO. Different solvents showed different effects on phenol profiles: low molecular alcohol aqueous solution could extract more phenolic compounds, while gallic acid as a solely compound was extracted by acetone. These factors indicate that SECO should be refined and solvent effect on phenolic compound extraction would be helpful on further research for the interested phenol fraction in camellia oil.
