| Abstract | Tea oil produced from seed of Camellia oleifera, which can be used as healthycooking oil and also as raw materials for cosmetic products. Recently, tea oil has beencommercially launched to domestic market in Thailand. However, standard qualities hadnot yet been established. This study aimed to prepare data base for Thai standard in thefuture and was performed at Postharvest and Processing Research and DevelopmentDivision in 2013. The black, brown and yellowish-brown seeds from the experimentalplots of The Chaipattana Foundation, Chiang rai province were harvested and analyzed tofind out basic compositions which are moisture content, oil content, protein content andcrude fiber content. It was shown that black seeds gave better quality due to highest oilcontent (22.77%) and lowest moisture content (2.58%). After analysis of tea oil theresults showed that oil from fresh harvest seeds presented better qualities due to lowacid value (4.94 mgkoH/g) and peroxide value (0.97 meq/kg) comparing with aged seeds.In addition, domestic and imported tea oil were sampling to analyze physical andchemical properties as well as nutrition facts. High amount of oleic acid was found inboth domestic (9.21-74.88%) and imported (7.07%) tea oil. Using TISI standard for "oiland edible fat" along with CODEX standard of olive oil as bench-mark, it was shownthat they complied the requirements of both standards. These information can beproposed to guide a specific draft national standard for tea oil. |
