| Abstract: |
| In order to improve the extraction rate of flaxseed oil, the oil was extracted from flaxseed by pectinase method. The effects of solid-liquid ratio, enzymatic hydrolysis temperature and enzymatic hydrolysis time on the extraction rate of flaxseed oil were investigated by single factor experiment, and on this basis, the process conditions of extracting flaxseed oil with pectinase were optimized by response surface methodology. The results showed that the optimal conditions for the extraction of flaxseed oil by pectinase method were obtained as follows: solid-liquid ratio 1∶5, dosage of pectinase 3%, enzymatic hydrolysis temperature 56℃, and enzymatic hydrolysis time 6 h. Under these conditions, the extraction rate of flaxseed oil was 85.64%. Therefore, pectinase can effectively extract flaxseed oil. |
