Optimization of extracting Qiubei chilli seed oil by solvent enzymatic method
The comminution degree of chilli seeds,solvent selection,solvent quality,enzyme selection,enzyme amount used,enzymatic temperature,enzymatic time,and initial pH were selected as the factors for single-factor test in the paper. Petroleum ether and compound enzymes(cellulase and protease) were respectively selected as extraction solvent and experiment enzymes. The chilli seed was 80 mesh particle sizes,enzyme dosages were 0.4% cellulase and 0.6% neutral protease and solvent dosage was 1∶10. On this basis,enzymatic temperature,enzymatic time,solvent quality and initial pH were selected for further carrying on L9(34) orthogonal experiment. Some results were gained from that,while enzymatic temperature was 50 ℃,enzymatic time was 11 h,solvent quality was 1∶9 and initial pH was 5.5,the extraction rate was higher.
