Abstract:The response surface methodology (RSM) was adopted to optimize the microwave-assisted n-Hexane extraction of essence oil from orange peel. By single factor test, the impacts of extraction time, extraction temperature and the dose of extraction agent on extraction rate of total essence oil from orange peel were investigated. The results showed that the optimal microwave-assisted n-Hexane extraction conditions for essence oil from orange peel were as follows: extracting time 7 min, temperature 57 ℃ and the dose of extraction agent 275 mL. Under those conditions, the maximum value of the extraction rate was up to 2.221%.
