At the 2020 National Science and technology award conference just held, Qilu University of Technology (Shandong Academy of Sciences) (hereinafter referred to as "Qilu University of technology") won two second prizes of national science and technology progress. This is the first time that the university has won two national science and technology progress awards in a year, and its number of awards ranks in the forefront of colleges and Universities Affiliated to Shandong Province. It is also another major breakthrough in the deep integration of science and education, industry and education since the integration of Qilu University of technology and Shandong Academy of Sciences. It is understood that Professor Ji Xingxiang of the State Key Laboratory of bio based materials and green papermaking, as the first person to complete the project of "key technologies and industrialization of green preparation and high-value utilization of high-performance wood chemical pulp", won the second prize of national scientific and technological progress award in 2020; In addition, the project of "key technology and application of sea cucumber functional component analysis and intensive processing" participated by researcher Liu Changheng of Institute of biology won the second prize of national science and Technology Progress Award in 2020. Ozone "bleaching" and "eating through" sea cucumber are the winning keywords of the two national science and technology awards of Qilu University of technology. Ozone intervention, so that pulp bleaching bid farewell to "chlorine toxicity" In Shandong Chenming paper industry, there is a wood pulp production line with an annual output of 1 million tons. Its special feature is that there is almost no pollution in the whole process, and the high-quality pulp produced is also used for high-end paper. If we trace the technical source of this production line, we will come to the State Key Laboratory of bio based materials and green papermaking of Qilu University of technology. "Although the name of the project is long, in the final analysis, the core is only 'green'." Ji Xingxiang, director of the Light Industry Department of Qilu University of technology and executive deputy director of the State Key Laboratory of bio based materials and green paper, has pointed out the core competitiveness of the project for many years. In the traditional pulp production process, pulp bleaching usually reacts with acid through sodium hypochlorite, and the bleaching process takes one and a half to two hours, which is usually called "chlorine bleaching". After years of tackling key problems, Ji Xingxiang's team finally solved this problem: "chlorine bleaching contains certain toxicity, so the production process has potential harm to the surrounding environment, and the bleaching time is long, which will also have an adverse impact on the quality of pulp." Ji Xingxiang said: "in our technology, bleaching with ozone through oxidation is not only non-toxic, but also instant bleaching, basically realizing 'zero pollution'." In the production of pulp, the fiber in wood is the final component of pulp, and the separated lignin is the main material to blacken the wastewater. In Ji Xingxiang's opinion, "we have separated the lignin in the black liquor, so that the waste liquid generated in pulp production becomes clear. The separated lignin can be used as adhesive for wood processing, pigment dispersant and water reducer for cement, which not only solves the problem of wastewater treatment, widens the industrial chain of pulp and paper, but also produces new economic benefits." Since 2015, the scientific research achievements of Ji Xingxiang's team began to go out of the laboratory and fell to the ground in Chenming paper industry. "In fact, there are still many problems to be solved when entering the production line from the laboratory. The whole technical system will not be gradually improved until 2017." Ji Xingxiang said that now this production line has become the production line with the highest technical content of the enterprise. Sea cucumber is delicious. How is it delicious? How to eat well? Literally, the project of "analysis of sea cucumber functional components and key technologies and applications of intensive processing" seems to be more "people's livelihood", but its R & D process is not simple. It brings together the results of cross field research of 7 units and 10 researchers. In the words of Liu Changheng, chief engineer of the Institute of biology of Qilu University of technology, this project "solves the problem of how to eat sea cucumber well and understand it". In the eyes of ordinary people, sea cucumber with "q-bomb" represents high protein and low fat, because collagen is its main component. But in the view of Professor Xue Changhu of Ocean University of China, this is not the case. "Through research, we found that the fat content in some sea cucumbers is not low, more than 20%, but different from other animal lipids, sea cucumbers have the highest nutritional efficacy," he said From the molecular structure of "dissecting" sea cucumber, they found that: sea cucumber sulfate polysaccharide is one of its main functional components. Some sea cucumber sulfate polysaccharides protect the stomach, some are anticoagulant, and some sea cucumber eat "hot throat", which is actually caused by sea cucumber saponins, which has certain anti-tumor and hemolytic effects. "Through the deep combination of industry, University and research, the basic research of the whole team has actually played a great role in promoting the development of sea cucumber industry." Liu Changheng told reporters, "now instant sea cucumber is very popular, but the technology of instant sea cucumber basically comes from our team, because as early as 2003, we developed the first instant sea cucumber in China." How to eat sea cucumber? There is a scientific stress in it. Liu Changheng said: "the more you know about sea cucumber, the better you can eat it. The research found that some people are difficult to absorb the large protein molecules of sea cucumber. We developed biological enzymatic hydrolysis technology to convert the large molecules into small molecules for easy absorption." Sea cucumber oral liquid, sea cucumber capsule, sea cucumber buccal tablet and sea cucumber granule... Based on the analysis of sea cucumber components and intensive processing technology of this scientific research team, the industry university research cooperative enterprise has developed and issued a series of sea cucumber deep-processing products, which are favored by the majority of consumers. With 20 years of efforts, this cross unit scientific research team has focused on the sustainable development of the whole industrial chain of sea cucumber. The reporter learned that many of their technical achievements have been extended to many domestic sea cucumber processing enterprises. It is worth noting that the existing domestic sea cucumber processing standards are also formulated and revised by this team. "Over the past 20 years, the sea cucumber industry has increased more than 10 times. I hope our research can make people eat sea cucumber more clearly and make the development of sea cucumber industry more transparent and standardized," Liu Changheng said (Xinhua News Agency)
