沃柑皮香精油提取及挥发性成分分析.

The experiment was to use pressing method to extract the essential oil of citrus peel, and optimized the extraction process of essential oil from peel of citrus citrus through several sets of experiments. The composition of essential oil was analyzed by gas chromatography-mass spectrometry. The results showed that the optimal extraction conditions of citrus peel essential oil were liquid to soild ratio of 10 mL/g, pH value of 11, the ultrasonic power of 320 W, and treatment time of 70 min. Under these conditions, the oil yield of essential oil extracted from citrus peel by pressing could reach 3.89%. The test reproducibility was good. A total of 48 compounds were detected in essential oils, including thymol, cinnamaldehyde, carvacrol and other active compounds that were widely used in livestock and poultry breeding. The study indicates that the extraction process of citrus peel essential oil is stable and feasible, and obtained essential oil has potential application value in feed. [ABSTRACT FROM AUTHOR]
