Optimization of Processing Parameters for the Blitzkrieg Extraction of Noni (Morinda citrifolia L) Seed Oil

摘要

A simple and rapid blitzkrieg extraction procedure has been developed and optimized for hexane extraction yield from the noni (Morinda citrifolia L) seed. Several variables that could potentially affect the extraction efficiency, namely, solid: liquid ratio (g/mL), blitzkrieg extraction voltage (V), extracting time (s) have been optimized by means of response surface methodology (RSM). The optimum conditions were the ratio of material to liquid 95g/500mL, blitzkrieg extraction voltage 148V and extracting time 79s. Under the optimum operating conditions, the extraction yield was 10.42%, a drastic reduction of the blitzkrieg extraction time (79 s vs. 8 h) was achieved, comparable with the reflux extraction.
