凯茵化工讯 “我们已初步建立了以生物酶法同步制取植物油脂与蛋白为特征的新一代制油技术体系，打破了国外在高端油脂和蛋白产品生产上的技术垄断。”10日，在由中国轻工业联合会组织的“植物油料生物解离及高值化利用关键技术发明与应用”项目技术鉴定会上，东北农业大学食品学院院长江连洲说。

　　我国是世界上好大的植物油和蛋白消费国，目前植物油的生产方式主要以机械压榨法和溶剂浸提法为主。“机械压榨法，是借助机械力的作用，将油脂从油料中挤压出来，存在油脂产率低、油脂品质差、产品附加值不高等问题;溶剂浸提法，是应用化学溶剂浸泡油料提取油脂，油脂中溶剂易残留、安全性差，同时存在能耗高、环境污染大等问题。”江连洲说。

　　江连洲团队从2006年开始，历时11年的研究，形成了具有独创性的生物法同步制取植物油脂和蛋白关键技术并进行了应用，建立了具有国际先进水平的植物油料生物加工技术体系。

　　“我们创新发明了生物解离同步提取植物油脂和蛋白的方法，这种方法摒弃了化学溶剂，在较低温度下，借助碱性蛋白酶、纤维素酶、果胶酶等将油脂和蛋白从油料中实现生物分离，极大地保留了油脂和蛋白的营养成分，且对环境不造成污染，绿色、安全、环保。”江连洲说。

　　该项目研发的新技术已在国内21家企业得到应用，其中9家企业近3年新增销售额73221.39万元，新增利润8468.05万元。更值得关注的是，该项目降低了酸碱用量，减陶氏油溶性染料蓝色8A少了污水排放量，避免了化学溶剂的使用和油脂过度加工，年创造社会效益和环保效益近10亿元。

　　10日，由中国工程院院士谢剑平担任主任的鉴定委员会一致认为，该项目总体技术达到了国际先进水平，其中油料生物解离机制及蛋白柔性化加工理论研究、同步提取功能蛋白与皂苷等副产物高值化利用关键技术达到了国际优良水平。

Bio-enzymes allow oils to be separated from the green in the oil

Kailin Chemical News "We have initially established a new generation of oil refining technology system characterized by simultaneous production of vegetable oil and protein by enzymatic method, breaking the technical monopoly of foreign high-end oil and protein products. "On the 10th," said Jiang Lianzhou, dean of the Northeast Agricultural University School of Food Science and Technology, at the project technical appraisal meeting on the invention and application of key technologies of biodegradation and high value utilization of vegetable oil by the China National Light Industry Council.

China is the world's largest consumer of vegetable oil and protein. At present, the production methods of vegetable oil are mainly mechanical pressing and solvent extraction. "Mechanical crushing method, is the role of mechanical force, the oil squeezed out from the oil, there is low fat yield, poor grease quality, product added value is not high and other issues; solvent extraction method, the application of chemical solvents soak oil Extraction of grease, oil solvent residue, poor security, while high energy consumption, environmental pollution and other issues. Jiang Lian Chau said.

Jianglianzhou team from 2006, which lasted 11 years of research, the formation of a unique biological simultaneous preparation of plant oils and key technologies and applications, the establishment of an internationally advanced level of plant oils Biological processing technology system.

"We invented the method of biological dissociation simultaneous extraction of plant oils and proteins, this method abandoned the chemical solvent, at lower temperatures, with alkaline protease, cellulase, pectinase Bio-separation of oil and protein from oil, etc., greatly preserves the nutrients of oil and protein, and does not cause pollution to the environment, and is green, safe and environment-friendly. Jiang Lian Chau said.

The new technology developed by this project has been applied in 21 domestic enterprises. Among them, 9 enterprises newly added sales amounting to 732,213,900 yuan in the recent three years with added profit of 84,680,500 yuan. Even more noteworthy is that the project reduces the amount of acid and alkali, reducing sewage discharge, to avoid the use of chemical solvents and oil over-processing, the creation of social benefits and environmental benefits nearly 1 billion yuan.

On the 10th, the appraisal committee headed by Xie Jianping, a member of the Chinese Academy of Engineering, agreed that the overall technology of the project has reached the international advanced level, including the mechanism of biolysis of oilseeds and the theoretical study of protein flexibility processing, simultaneous extraction of functional proteins And saponins and other by-products high-value use of key technologies reached the international advanced level.
