| 中文摘要: |
| 为给玉米油的精准适度精炼工艺研究提供参考，探究兼顾植物甾醇保留的玉米油水化脱胶工艺，以玉米原油为原料，以植物甾醇和磷脂含量为考察指标，采用单因素实验和响应面实验对玉米油水化脱胶条件进行优化。结果表明：最优的水化脱胶条件为脱胶温度58℃、加水量4.38%、脱胶时间55 min，在此条件下脱胶油中的磷脂含量为0.76 mg/g，脱胶率为92.95%，植物甾醇含量为1 239.00 mg/100 g，植物甾醇保留率为83.35%。 |
| 英文摘要: |
| In order to provide a reference for the research of precise and moderate refining of corn oil, the process of hydration degumming of corn oil taking into account the retention of phytosterol was investigated. Taking crude corn oil as raw material, the hydration degumming conditions of corn oil were optimized by single-factor experiment and response surface methodology with phytosterol and phospholipid contents as the indexes.The results showed that the optimal hydration degumming conditions of corn oil based on phytosterol retention were obtained as follows:degumming temperature 58℃, water dosage 4.38% and degumming time 55 min. Under these conditions, the content of phospholipid in degummed oil was 0.76 mg/g and the degummed rate was 92.95%, the content of phytosterol was 1 239.00 mg/100 g, and its retention rate was 83.35%. |
