China Canada school enterprise cooperation: using membrane separation technology to remove heavy metals and pesticide residues in natural plant extracts

Great Wall network Qinhuangdao news (reporter zudi correspondent Wang Jijun) on July 31, Qinhuangdao Changsheng nutrition and Health Technology Co., Ltd signed a cooperation agreement with Professor boguslaw kruczek of Ottawa University, Canada The two sides will cooperate on the project of removing heavy metals and pesticide residues in natural plant extracts by membrane separation technology, which is the first time in China According to reports, in recent years, China's natural plant extract industry has been full of vitality Natural plant extracts can be used as raw materials, widely used in food, medicine, health products, cosmetics and other industries However, in the process of removing heavy metals and agricultural residues with natural plant extracts, due to the problems of equipment not easy to clean, high production cost, poor removal effect and low efficiency, high energy consumption, the industrial promotion is affected Qinhuangdao Changsheng nutrition and Health Technology Co., Ltd is mainly engaged in the research of asparagus deep processing technology and the high-tech industrial development of asparagus effective ingredients At present, it is in the leading position in the field of asparagus deep processing at home and abroad The company focuses on the development and research of natural plant extracts, and actively carries out strong cooperation mode to break through technical problems Since 2008, Changsheng technology has stepped up the pace of transformation and upgrading, committed to the path of industry university research cooperation, and established a national asparagus industry alliance with sun Baoguo, academician of the Chinese Academy of engineering, as the technical consultant, and nine units as members, including the Institute of process engineering of the Chinese Academy of Sciences, China Agricultural University, Jiangnan University, Beijing University of chemical technology, Nanchang University, Hebei Normal University of science and technology; It has jointly established the first "asparagus biological refining laboratory" in China with the Institute of process of Chinese Academy of Sciences, and "asparagus functional food research and development center" with China Agricultural University In recent years, the company has undertaken 17 national, provincial and municipal scientific research projects, completed 9 scientific research achievements, applied for 15 related invention patents, and authorized 5 Since this year, Changsheng Technology Co., Ltd has taken the lead in the industry to propose the idea of effectively removing pesticide residues and heavy metal residues by membrane filtration, and selected professor boguslaw kruczek, a famous membrane separation technology expert from Ottawa University, Canada, to jointly develop and utilize internationally advanced membrane separation technology to effectively remove heavy metals and agricultural residues in natural plant extracts Professor boguslaw kruczek has been devoted to the research of membrane separation technology for many years He is especially good at the development and characterization of membrane materials, familiar with the principle and characteristics of membrane separation process, and successfully transformed his research results The project, with an investment of 2 million yuan, is planned to be completed by the end of this year, with the help of boguslaw According to Professor kruczek's technical experience, it is proposed to adopt the innovative method of membrane separation technology combined with activated carbon adsorption technology, and determine the production parameters of each equipment in combination with the actual production needs On the basis of ensuring the taste and nutrition of asparagus extract, control the removal rate of heavy metals and agricultural residues to be more than 95%, reduce the loss of effective ingredients by more than 40%, and reduce the production cost by more than 20% After the technology is applied to the natural plant extract industry, the scale can reach more than 10 billion yuan This will greatly improve the overall removal level of heavy metals and pesticide residues in the industry, make China's natural plant extract industry reach the international level, and improve China's international competitiveness and market share of the industry "We believe that through today's cooperation, we can develop new technologies that can effectively remove heavy metals and pesticide residues in natural extracts, which are convenient in technology application, easy to operate and promote equipment, can significantly reduce production costs and energy consumption, and make significant contributions to the development of natural plant extracts industry and large health industry."
