超声波辅助乙醇提取茶叶籽油的工艺研究

AbstractIn this paper,the tea seed of Fujian Province was selected as the experimentalraw material,and the tea seed oil was extracted by ultrasonic cleaning machinewith the aid of ethanol solution.The effects of ultrasonic washing machinepower,ultrasonic extraction time,ultrasonic extraction temperature,feed-liquidratio and ethanol mass fraction on oil yield of tea seeds were studied.Theoptimum extraction technology of tea seed oil was obtained by orthogonalexperiment.As a result,when the grain size of tea seeds was 20 mesh and themass fraction of ethanol was 80%,the temperature of ultrasonic cleaningmachine was set to 70C and super C according to the ratio of material toliquid to 1:14 When the sound wave power was 315 W,ultrasonic extractionwas carried out.After 100 min extraction,the yield of tea seed wool oilobtained after treatment could reach 26.13%,and the peroxide value was about0.052 mmol/kg.Keywords:tea seed oil;ultrasonic;ethanol;extraction
