Natural Products Company has another post-doctoral entrance examination

News 9# May 27 On the morning of the 7th, the entrance examination opening report of Dr. Li Dongnan of Shenyang Agricultural University was held in Tianjin Jianfeng Natural Products Company. This is the fifth doctor who has entered the station for postdoctoral research since the company's national postdoctoral workstation was established.

This post-doctoral research is part of the joint scientific research work carried out by the post-doctoral workstation of the natural product company and the post-doctoral mobile station of the School of Food Science and Engineering of Tianjin University of Science and Technology. Liu Dan, general manager of the natural product company, and Professor Zhang Zesheng of Tianjin University of Science and Technology Co-served as postdoctoral tutors.

The research topic of Dr. Li Dongnan is the mechanism of pectin improving the stability of anthocyanin in fruit juice. In the opening report, he elaborated the basic content, expected goal, current situation at home and abroad, scientific significance, academic value, application prospect, technical route, innovation points and proposed key issues of the research, he also accepted questions from an expert group composed of Professor Du Xinjun, Dean of the School of Food Science and Engineering of Tianjin University of Science and Technology, and Zhang Chunli, a senior engineer of a natural product company. After a comprehensive discussion between the instructor and the expert group, Dr. Li Dongnan innovatively introduced high hydrostatic pressure technology into the research of this subject, and used the extreme pressure conditions generated by high hydrostatic pressure to change the hydrogen bond, ionic bond and hydrophobic interaction between anthocyanin-

pectin in fruit juice, the effect of different non-covalent binding forms on the stability of anthocyanins was explored by studying the relationship between the interaction differences of anthocyanins - and the stability of anthocyanins in the same system, and the mechanism of pectin improving the stability of anthocyanins in fruit juice was further clarified, which made it possible to quantitatively adjust the stability of anthocyanins in water-based environment by using endogenous substances in fruits and vegetables, and provided new ideas for improving the stability of active substances in water-based environment; the experimental design of this topic is scientific and reasonable, and the goal is feasible. The existing experimental equipment and facilities of the workstation can meet the experimental needs. Dr. Li Dongnan has the ability to undertake the research of this topic and agrees to enter the station to start the topic.

Tianjin Jianfeng Natural Products Company's national post-doctoral workstation was established in 2005

. Up to now, 4 doctors have completed the research and successfully left the station. Some research results have been applied in product research and development and production. (Mu Ruixin)

Peak natural products among the top 20 scientific and technological innovation in TEDA

A few days ago, Tianjin Jianfeng Natural products Research and Development Co., Ltd. stood out among nearly 35000 enterprises in Tianjin Development Zone and won the honor of "Top 20 Scientific and technological Innovation Enterprises of 2015. The selection criteria for the top 20 scientific and technological innovation enterprises in Tianjin Economic and Technological Development Zone mainly include: they have won science and technology awards or patent awards in 2015, as well as other awards above the provincial level; they have obtained the qualification certification or approval of research and development institutions above the provincial level; in 2015, the number of invention and utility model patent applications and authorizations was large, totaling more than 15; in 2015, they were supported by national or Tianjin key science and technology plans; scientific research achievements have made significant progress and technology. According to the above standards, Jianfeng Natural Products Company has not only won the second prize of Tianjin Science and Technology Innovation Project Award for the achievements of "Tianjin Plant Waste Reutilization Technology Engineering Center Construction", but also completed the process research of grape seed extract and ginsenoside to pesticide residues, and formulated the international business standard of grape seed extract (grape seed oligomeric proanthocyanidins). In order to better carry out the pilot experiment, large-scale technical transformation was carried out on the second workshop, and the process optimization of extracting anthocyanins from blueberries has been carried out. At the same time, the main business income, operating profit, tax revenue and other economic indicators of peak natural products company in 2015 have increased significantly year-on-year. Relying on the advantages of excellent quality, good efficiency, great contribution, safety and environmental protection, and good social responsibility, Jianfeng Natural Products Company successfully passed the review and became one of the "Top 20 Scientific and Technological Innovation Enterprises in 2015" in Tianjin Development Zone.

Peak pharmaceutical "enterprise information construction project" through the acceptance

The "Enterprise Informatization Construction Project" of Jianfeng Pharmaceutical Company was included in the list of key projects of "Integration of Industrialization and Industrialization" (high-level and in-depth combination of informatization and industrialization) in Jinhua City in 2015, and successfully passed the on-site acceptance of the expert group on the morning of May 18. The main contents of the "enterprise information construction project" of the pharmaceutical company include: the tank farm control system, which solves the problem of closed metering and transportation of organic solvents between the tank farm and the production area, can automatically realize the terminal metering setting, and effectively ensure the safety and environmental protection requirements of the tank farm operation; The air conditioning automatic control system realizes the control of the temperature, humidity and room pressure difference in the air conditioning area through the PLC digital-to-analog conversion of the upper computer and lower computer and the terminal actuator regulator, ensure the cleanliness requirements of the production area environment; The online particle monitoring software system automatically adjusts to the standard flow through the upper computer, vacuum system, laser sensor and isodynamic sampling probe, etc. through the flow detector device and key orifice plate inside each sensor, monitors the temperature, humidity, particles, planktonian bacteria, room pressure difference, etc., implements dynamic management, and realizes visual monitoring of the production process environment. MRP production management system, it makes it easier for the warehouse, workshop, and management personnel to obtain information about the flow of materials in the production process, the implementation of production plans, and product inventory. During the on-site acceptance on the 18th, the acceptance team composed of the Information Department of the Municipal Economic and Information Commission, the Economic and Development Bureau of the Development Zone, the Municipal Information Promotion Association and professors of Zhejiang Normal University checked the contracts of each system software, purchase and transfer records, training records, and problem records in project implementation,
