Effect of particle size on the oil yield and catechin compound using accelerated solvent extraction

Abstract

The purpose of this work is to investigate the effects of particle size on the extraction of catechin compound from Areca catechu L. seeds by using Accelerated Solvent Extraction (ASE). The particle sizes of Areca catechu L. seeds are varied from 75 μm until 500 μm. The extraction is conducted at fixed parameters which are temperature (140°C), pressure (1500 psi), extraction time (10 minutes), flush volume (60%) and the static cycle is done for 1 extraction cycle respectively. Higher percentage oil yield of 300 mg oil/gram of sample (30.00% oil yield) is found at 125 μm. However, the amount of catechin in oil yields is only 0.0375 mg of catechin/gram of sample. The best of particle size within the experimental range has been identified at 500 μm which gives a high content of catechin with 0.0515 mg Catechin/gram of sample from 247.5 mg oil/gram of sample (24.75% oil yield)
