Optimization of Simultaneous Distillation Extraction of the Black Pepper
Abstract:
The aim of this work was to optimize a simultaneous distillation-extraction (SDE) procedure for the volatile compounds of black pepper (Piper Nigrum L.). Several variables that could potentially affect the extraction efficiency, namely, the liquid: solid ratio (volume per mass), soaking time and simultaneous distillation-extraction time have been optimized by means of response surface methodology (RSM). The optimum technology conditions have been attained by RSM as follows: the ratio of liquid to solid 25:1, simultaneous distillation-extraction time 3h and the soaking time 1.5h, under the optimum operating conditions, the extraction yield was 1.458%.
