| 中文摘要: |
| 为了加强精炼油脂的质量安全，提高市场竞争力，对多品种油源，改进油脂精炼工艺和设备。在原有油脂精炼工艺及设备改进的基础上，采用新工艺如酶法脱胶、纳米中和、后脱酸等，保留油中活性物质如甾醇、维生素E，控制反式酸增量在1.2%以内、缩水甘油酯含量小于等于1 mg/kg、3-氯丙醇酯含量小于等于2.5 mg/kg，节能降耗，降低生产成本。 |
| 英文摘要: |
| In order to strengthen the quality safety of refined oil and improve the market competitiveness, the oil refining process and equipment for multiple oil sources were improved. Based on the improvement of the original oil refining process and equipment, the new processes were adopted such as enzymatic degumming, nano-neutralization and post deacidification to retain the active substances (sterol and vitamin E) in oil, control the trans fatty acid increase no more than 1.2%, the content of glycidyl ester no more than 1 mg/kg and 3-chloro-propanediol ester content no more than 2.5 mg/kg, save energy and reduce production cost. |
