摘要
探讨了以粉碎 绝氧陈化 紫外线激活的方法 ,让柑橘皮中的自体酶发酵催化 ,将柑橘香精油中的d 柠檬烯转化成含氧萜烯类 ,降低了香精油中碳氢萜类含量 ,相对提高了含氧萜烯类含量 ,从而明显地提高了柑橘香精油的产量和香气品质。文中以冷榨、高速离心分离、己烷低温浓缩的方法从湖北宜昌所产柑橘皮渣中成功地提取了柑橘香精油 ,产率达 8.81 g/kg。
In this paper, the author extralted the citrus essential successfully from citrus peel, using cold-press,high -speed centrifugal separation and hexane concentration under cool conditions. The recovery rate was 8.81?g/kg citrus. The author also explores using crush-anoxybiotic-ageing-ultraviolet method. It was based on the endogenous enzymes fermentation in citrus peel to corwert d-limonene into oxy-terpene. This method could increase the amount oxy-terpene in citrus peel. The result showed a new method in producing high-quality and quantity of essential oil.
