| Abstract: | Taking Lin＇ an wild walnut as raw materials,assisted by ultrasonic wave,the processing technique of extracting walnut oil was investigated.The results indicated that the optimum conditions were as follows：the ratio of cellulase,hemicellulase,pectinase and neutral proteinase 2∶5∶2∶4; the ratio of material and water 1∶5,optimum amount of enzyme 1.6％,enzymatic hydrolysis temperature 45℃,enzymatic hydrolysis pH 7.0,enzymatic hydrolysis time 3 h.Under this condition,walnut oil extraction rate achieved 54.23％. |
