将水分为0.1%、0.5%、1.0%的小桐子毛油,以棕色塑料瓶、白色塑料瓶和透明玻璃瓶密封包装后在20、30、40℃的条件下储藏160 d,每20 d测定1次酸值和过氧化值,研究小桐子毛油在不同储藏条件下品质变化情况。结果表明：随着储藏温度的升高、小桐子毛油水分的增加以及储藏时间的延长,小桐子毛油的酸值和过氧化值均增加。采用正交实验得到小桐子毛油适宜的储藏条件为：棕色塑料瓶密封包装,水分0.1%,储藏温度15℃；在此条件下,小桐子毛油储藏180 d后,其过氧化值上升,酸值未发生明显变化。
將水分為0.1%、0.5%、1.0%的小桐子毛油,以棕色塑料瓶、白色塑料瓶和透明玻璃瓶密封包裝後在20、30、40℃的條件下儲藏160 d,每20 d測定1次痠值和過氧化值,研究小桐子毛油在不同儲藏條件下品質變化情況。結果錶明：隨著儲藏溫度的升高、小桐子毛油水分的增加以及儲藏時間的延長,小桐子毛油的痠值和過氧化值均增加。採用正交實驗得到小桐子毛油適宜的儲藏條件為：棕色塑料瓶密封包裝,水分0.1%,儲藏溫度15℃；在此條件下,小桐子毛油儲藏180 d後,其過氧化值上升,痠值未髮生明顯變化。

The crude Jatropha oils with different moisture contents of 0 . 1%, 0 . 5% and 1 . 0% respec-tively sealed in brown plastic bottle, white plastic bottle and transparent glass bottle were stored at 20, 30℃ and 40℃ for 160 d, and the acid values and peroxide values of the crude Jatropha oils were meas-ured every twenty day to study the quality change of crude Jatropha oil under different storage conditions. The results showed that the acid value and peroxide value of crude Jatropha oil increased with the increas-ing of storage temperature and moisture content and the extension of storage time. The optimal storage con-ditions of crude Jatropha oil were obtained by orthogonal experiment as follows:brown plastic bottle sealed packaging, moisture content 0. 1%, storage temperature 15℃. Under the optimal conditions, after storing for 180 d,the acid value of crude Jatropha oil did not change significantly, while peroxide value increased.
