摘要
以不同工艺(冷榨法、热榨法、超临界CO2萃取法、水酶法、浸出法、鲜榨法)山茶油为研究对象,研究了其多酚、黄酮、原花青素、总三萜和木脂素含量。结果表明:冷榨毛油中多酚、黄酮、原花青素、木脂素和总三萜含量高于浸出毛油;超临界CO2萃取山茶油和水酶法山茶油中多酚、黄酮、总三萜和木脂素含量较高;鲜榨山茶油中多酚、黄酮、原花青素、木脂素和总三萜含量分别为271. 6、157. 2、1 400. 0、180. 0 mg/kg和12. 5 mg/g,均远高于其他工艺。鲜榨山茶油是一种高品质食用油,具有广阔的食用和药用价值。
With oil-tea camellia seed oils from different processes( cold pressing,hot pressing,solvent extraction,supercritical CO2 extraction,fresh pressing and aqueous enzymatic extraction) as research objects,the contents of polyphenols,flavonoids,procyaninides,total triterpenoids and lignins were studied. The results showed that the contents of polyphenols,flavonoids,procyaninides,total triterpenoids and lignins in crude cold pressed oil were higher than those in crude solvent extracted oil. The contents of polyphenols,flavonoids,total triterpenoids and lignins in oil-tea camellia seed oils extracted by supercritical CO2 and aqueous enzymatic method were higher. The contents of polyphenols,flavonoids,procyaninides,lignins and total triterpenoids in fresh pressed oil-tea camellia seed oil were 271. 6,157. 2,1 400. 0,180. 0 mg/kg and 12. 5 mg/g,which were far higher than those in the other five processes.The fresh pressed oil-tea camellia seed oil was a kind of high-quality edible oil,and had wide edible and medicinal value.
