| 摘 要： | 对不同工艺生产的油茶籽油，在不同贮藏条件下长期贮藏后的酸值、过氧化值和VE含量进行测定。结果 表明：各种成品油的酸值和过氧化值随贮藏时间的延长而上升，而VE的含量下降。全程低温工艺精炼的油茶籽油 经过长期贮藏后，其酸值和过氧化值的增加量与一级压榨油相当，但明显低于高温精炼油。在高温、光照等不良贮 藏条件下，低温工艺精炼的油茶籽油的优势很明显，品质劣变程度小。 |

| Abstract: | The acid value, peroxide value and vitamin E content of Camellia oleifera seed oil produced from different refining processes under different storage conditions were continuously analyzed during the storage period. Results indicated that acid value and peroxide value of the oil increased constantly, while the content of vitamin E decreased during prolonged periods. The acid value and peroxide value of the oil refined from lower-temperature refining process showed roughly the same change patterns as the first-class pressed oil; however, both values were significantly lower than those of the oil refined from the classical refining process. More obvious advantages of the oil refined from lower-temperature refining process were observed when exposed to stress storage conditions such as high temperature, high light intensity during long-term storage. |
| Keywords: | refining temperature storage conditions quality Camellia oleifera Abel seed oil |
