| 中文摘要: |
| 利用高效液相色谱法研究压榨法和浸出法对山茶油中α-维生素E含量的影响，并测定不同加工工艺过程中α-维生素E含量的变化。结果表明：压榨山茶油毛油中α-维生素E含量平均为27.1 mg/100 g，压榨成品油中α-维生素E含量平均为25.4 mg/100 g，压榨精炼油中α-维生素E含量平均为19.3 mg/100 g；浸出山茶油毛油中α-维生素E含量平均为17.9 mg/100 g，浸出精炼油中α-维生素E含量平均为14.3 mg/100 g。通过对不同加工工艺的山茶油毛油和成品油、精炼油中α-维生素E的比较可知，加工过程会使α-维生素E的含量减少，但α-维生素E的保留率都在71%以上；压榨成品油中α-维生素E含量明显高于浸出精炼油中α-维生素E含量。 |
| 英文摘要: |
| The effects of pressing method and solvent extraction method on α-vitamin E content were studied by high performance liquid chromatography，and the content changes of α-vitamin E in different processes were determined. The results showed that the average α-vitamin E contents in crude pressed oil-tea camellia seed oil，finished pressed oil-tea camellia seed oil，refined pressed oil-tea camellia seed oil，crude solvent extracted oil-tea camellia seed oil and refined solvent extracted oil-tea camellia seed oil were 27.1,25.4,19.3,17.9 mg/100 g and 14.3 mg/100 g respectively.The α-vitamin E content decreased during processing，but the retention rate of α-vitamin E was more than 71%. The α-vitamin E content in finished pressed oil-tea camellia seed oil was significantly higher than that in refined solvent extracted oil-tea camellia seed oil. |
