摘要

近年来，将电加热技术集成到传统蒸馏系统中已经引起了人们对精油蒸馏的相当大的兴趣。其中一种方法是欧姆辅助加氢蒸馏（OAHD）。该技术集成了欧姆加热和加氢蒸馏（HD）。本研究考察了各种原料，包括新鲜柑橘皮、烘干柑橘皮和晒干柑橘皮对OAHD和HD的影响。评估的参数包括提取时间、出油率、能耗、化学成分和感官特性。OAHD的提取时间明显快于HD，沸点为8.10 ~ 9.35 min，而HD为27.83 ~ 31.99 min。OAHD的精油得率为8.8 ~ 14.9%，HD为5.8 ~ 11.9%。OAHD的能耗也较低，表明工艺效率较高。d -柠檬烯被确定为所有处理的主要化合物。感官评价显示，新鲜果皮精油具有清新、酸甜的香气，而干燥果皮精油则表现出较强的草药和木本气味。综上所述，OAHD在柑橘精油的提取过程中具有重要的工艺强化意义，是一种优秀的方法。

Ohmic-assisted hydrodistillation as an effective approach for high-yield citrus essential oil extraction

In recent years, the integration of electrical heating techniques into conventional distillation systems has garnered considerable interest in the distillation of essential oils. One such approach is ohmic-assisted hydrodistillation (OAHD). This technology integrates ohmic heating and hydrodistillation (HD). This study examines the impact of various raw materials, including fresh citrus peel, oven-dried citrus peel, and sun-dried citrus peel, on OAHD and HD. Parameters evaluated included extraction time, oil yield, energy consumption, chemical composition, and sensory characteristics. The extraction time of OAHD was significantly faster than HD, with a boiling point of 8.10–9.35 min compared to 27.83–31.99 min in HD. The yield of essential oils produced by OAHD was 8.8-14.9% compared to HD, 5.8–11.9%. Energy consumption was also lower with OAHD, indicating higher process efficiency. D-limonene was identified as the predominant compound across all treatments. Sensory evaluation revealed that essential oils from fresh peels had a fresh, sweet–sour aroma, while those from dried peels exhibited stronger herbal and woody notes. Overall, OAHD emerges as an excellent method with significant implications for process intensification in the extraction process of mandarin citrus essential oils.
