| 中文摘要: |
| 对分子蒸馏技术精制灵芝孢子油的工艺条件进行了研究，考察了分子蒸馏工艺参数对降低灵芝孢子油酸值和过氧化值的影响。通过单因素和正交实验确定的最佳工艺参数为：蒸馏温度200℃，进样速率2 mL/min，刮板转速160 r/min，冷凝温度50℃。在最佳工艺条件下，灵芝孢子油酸值（KOH）从17.00 mg/g降到0.40 mg/g，过氧化值从25.87 meq/kg降到5.21 meq/kg，总三萜化合物含量从3.01%降到2.87%，在可以接受的范围内。 |

| The single factor experiment and orthogonal experiment were employed to optimize the purification conditions of Ganoderma lucidum spore oil by molecular distillation. Effects of distillation temperature, feeding rate, revolving speed and cooling temperature on the acid value and peroxide value reductions of Ganoderma lucidum spore oil were studied. The results showed that the optimal process parameters for purifying Ganoderma lucidum spore oil by molecular distillation were as follows：distillation temperature 200℃, feeding rate 2 mL/min, revolving speed 160 r/min, cooling temperature 50℃. Under the optimal conditions, acid value decreased from 17.00 mgKOH/g to 0.40 mgKOH/g, peroxide value declined from 25.87 meq/kg to 5.21 meq/kg, and the total triterpenoids content reduced from 3.01% to 2.87%, which were within the acceptable range. |
