Luwang, January 21 (Reporter Zhuang Jiali) On January 21, the Propaganda Department of the Zibo Municipal Party Committee of the Communist Party of China held a press conference to release the 2021 "Moving Zibo" annual person to the public. Abide by science and technology to serve the country with innovation to break the international monopoly of the engineer - Liu Wenlai was elected as the 2021 "Moving Zibo" person of the year.
Liu Wenlai, male, 48 years old, doctoral candidate, food science major, senior engineer, is currently the technical director of Shandong Tianyin Biotechnology Co., Ltd., the director of Shandong Natural Plant Pigment Engineering Technology Research Center, the director of China Food and Ingredients Association, and the industry professor of Shandong University of Technology. He has won the May Day Labor Medal of Shandong Province, the Advanced Individual of Scientific and Technological Innovation of Small and Medium-sized Enterprises in Shandong Province, the Scientific and Technological Innovation Talent of Zibo City Talent Program, the Zibo Gold Medal Craftsman, the Talent Expert of Zibo Think Tank, and the Young and Middle-Aged Experts with Outstanding Contributions in Zhangdian District, and is the winner of the Zibo Labor Medal for Revitalization. He pays attention to technological innovation and creation, and has authorized more than 20 patents in the field of lutein, and a number of technologies are the first in China. In recent years, he has presided over the completion of 3 national scientific research projects and 13 provincial and municipal projects, and has strong technical research and development capabilities and innovation capabilities. Drafted and formulated 2 national food safety standards and 2 industry standards.
Relying on science and technology to revitalize enterprises, in order to achieve the combination of scientific and technological innovation and industrial development, Liu Wenlai has always adhered to the production of science and technology, long-term stationed in the production line, in response to the party's call of the times, active innovation, pioneering and enterprising, assiduous study of new technologies and new methods, combined with the company's actual situation, the existing process methods continue to improve and optimize, breakthroughs from practice, not only to achieve technological innovation, but also to produce tangible benefits. Over the years, Liu Wenlai with high enthusiasm for work into technological innovation, engaged in natural plant pigment research and development and technical work for 26 years, with his love of work, the study of professionalism, always with a conscientious attitude, on the real pragmatic, diligent and enterprising, the courage to dedicate the work style to perform job responsibilities, focusing on lutein extraction purification, isomerization, microencapsulation and other fields of research and industrialization work, pay attention to business learning, in the actual work of hard work to study business technology expertise, and actively promote new technologies and new processes He led the team to carry out technical research, do a good job in comprehensive management of technological innovation, etc., accumulated profound professional knowledge and rich technical practice experience in the development and production process of new lutein products, repeatedly overcome the core technical problems that have plagued the industry for many years, and promoted the high-quality development of lutein in China.
Solve the lutein microencapsulation "card neck" technology, develop 16 new products, and break the monopoly of foreign countries
Lutein, commonly known as "eye gold", has the functions of protecting vision, relieving eye fatigue, preventing age-related macular degeneration, etc., and is a new type of green functional food. Lutein is sensitive to light, oxygen and heat, so it leads to easy degradation of active substances, low bioavailability, and cannot prevent eye diseases well. At present, China's lutein production accounts for more than 80% of the world, mainly export-oriented, stable and bioavailable lutein microcapsule products are monopolized by the Netherlands DSM, Basf of Germany and other companies, China imports from abroad at high prices, huge profits are ingested by foreign countries, microencapsulated lutein products there is a "card neck" problem. At present, domestic scientific research institutions use hot melt melting, spray drying and other processes to prepare lutein microcapsule products, and their main active substances are about 80%, the retention rate of 3 months is about 80%, and the biological utilization rate is insufficient. In view of the problem, after a large number of experimental exploration, analysis and animal experiments, he constantly summed up the experience from failure, developed the wet nano low temperature grinding, ultra-high pressure homogenization and starch flow instantaneous molding double embedding and other key technologies to prepare nano-scale lutein microcapsule process, the main active substance of the product exceeded 90%, the retention rate reached 99%, the bioavailability rate increased by 25% compared with foreign products, the product price was only 50% of foreign, meeting the domestic demand for high-end lutein, reducing the incidence of eye diseases. It has broken the monopoly position of internationally renowned enterprises such as Kemin in the United States, DSM in the Netherlands, and BASF in Germany, filled the domestic gap, and led to the technological innovation of the entire industry.
Overcome foreign technical barriers, products sell well in foreign markets
In 2004, the outbreak of dioxin poisoning in Europe, the European Union further raised the standard of use of food additives, which cast a shadow on the export trade of many enterprises. "Toxic substances such as dioxins and benzopyrene in natural extracts are difficult to avoid, and how to remove them is a core technical problem in the industry for many years." For Liu Wenlai at that time, all the equations of answer had to be written from blank spaces. Different from previous experiments, in order to meet the import standards of the European Union, the analysis of dioxins and benzopyrene in plant extracts must be carried out in Germany, which greatly increases the time cost. "It's as if I became a trapeze artist, flying over with confidence, but flying back disappointed, again and again, day and night to experiment." The news of success came back two years later. Recalling the situation at that time, Liu Wenlai still has difficulty calming his mood: "This is an important turning point in the development of Tianyin Biotechnology Co., Ltd., breaking the technical barriers of the EU to export products to China. ”
Constantly innovate new technologies and new applications to help convert new and old kinetic energy
In recent years, green environmental protection has always been the main theme of national development, in response to energy conservation and emission reduction is imperative, all enterprises have carried out equipment upgrading, automated closed workshop dust-free bass, boilers have also been replaced by the latest natural gas technology. He has innovated and optimized the traditional n-hexane extraction lutein process, pioneered the butane subcritical lutein extraction process, the yield increased by more than 6%, the solvent loss was reduced from 30 kg / ton to 2 kg / ton, which can save more than 5 million yuan per year, while the core technology of dioxin and benzopyrene removal is applied in the subcritical extraction, and the quality indicators of marigold extract are better than the EU standard, with a cumulative output value of 3 billion yuan and a profit and tax of 500 million yuan. In terms of the production of marigolds in the whole industry chain, he led the team to create a new skill of "turning stones into gold and turning waste into treasure", and the remaining mother liquor and slag after plant extraction will be treated as waste in the industry's conventional treatment methods. Through technical public relations, the comprehensive recycling from the previous waste to the production of feed-grade powder products has been realized, and this technology, as a new patent of the company, not only reduces emissions to create millions of profits every year, but also contributes to the conversion of new and old kinetic energy and energy saving and emission reduction in the industry and Zibo. At present, he has developed a series of new products using peppers and marigolds as raw materials to account for more than 80% of the company's sales, creating great economic benefits.
"Frozen three feet, not a day of cold", in Liu Wenlai, we see the epitome of high-skilled talents in the new era, he practices extraordinary duties in the most ordinary posts with his perseverance spirit, he uses his own pursuit and dedication to make life bloom brilliantly in the natural pigment industry, which has played a positive role in the national technological progress and upgrading, and has made outstanding contributions to the mainland natural pigment extraction and deep processing industry, especially the production technology and industrialization of high-content and stabilizer lutein.
