摘要
探讨了 70℃和 95℃下 ,在常压和真空条件下加热过程对预纯化烤鳗油的酸价、过氧化值和碘价的影响。结果表明 ,在常压条件下 ,随加热时间加长 ,酸价和过氧化值呈线性增大。在真空条件下 ,酸价先呈上升趋势 ,在加热 9h以后 ,又趋于下降 ;于 70℃下过氧化值略有上升 ,而 95℃下则略有下降。在真空条件下碘价变化不大 。
The Influence of heat in the acid value, the peroxide value and the iodine number of prepurged roast eel oil at 70℃ and 95℃ in normal and vacuum condition were investigated. It was showed, the acid value and the peroxide value increased with heating time in normal condition. In vacuum, the acid value increased with heating in primary 9h, and decreased after 9h; and the peroxide value increased slightly at 70℃, and decrease a little at 95℃, respectively. The iodine number was stable in vacuum, and decreased a little in normal
