Soxhlet Extraction of White Pepper Oleoresin Technology

In this experiment,commercial white pepper as raw materials extracted by Soxhlet extraction of white pepper oil resin,and the choice of solvent,refluxing time,solid to liquid ratio,particle fragmentation,four factors on the extraction yield of pepper oil resin,the impact of the test.The results show that:the use of chloroform extract of white pepper oil resin with the highest rate,but because it has some toxicity of ethanol taken into account as the best solvent,Soxhlet extraction of various factors on the yield of white pepper oleoresin effect relationship between the primary and secondary the order:ACB,that the reflux timefragmentationliquid ratio,and extraction time on the pepper resin yield a very significant impact,solid to liquid ratio on the yield had significant effects,fragmentation of the yield of relatively significant.Extracted by Soxhlet extraction white pepper oleoresin optimal extraction condition was A3B1C3,distillation,extraction time 5h,solid to liquid ratio of 15:100,80 mesh particle fragmentation,under these conditions,white pepper oleoresin yield was 12.06%,better than the other conditions combined.
