摘　　要： 以甜橙和柠檬为主要原料,采用冷磨法进行柑橘精油提取,研究了浸泡剂浓度、浸泡时间、果皮破碎度、破乳剂添加量等对柑橘精油得率的影响。结果表明,柑橘精油提取最佳工艺条件为:浸泡剂石灰水浓度为3%,浸泡时间为1h,果皮破碎度为0.25cm,破乳剂NaCl添加量为0.75mg/mL。在此工艺条件下,甜橙精油得率为0.51%,柠檬精油得率为0.58%。 The influence of soaker concentration,soaking time,peel fragmentation,and the amount of demulsifier to the citrus essential oil extraction yield was studied in this paper with sweet orange and lemon as main raw materials by cold-pressed technique.The result showed that the optimum extraction conditions of citrus essential oils were as follows： soaker-limewater concentration 3%,soaking time 1 h,peel fragmentation 0.25 cm,demulsifier-NaCl 0.75 mg/mL,and sweet orange essential oil yield was 0.51%,lemon essential oil yield was 0.58% at this processing conditions.
