    Enterprise Profile

    Founded in 2000, Hangzhou Baojing Biological Co., Ltd. is located in Tangqi Ancient Town, Hangzhou, with a registered capital of 75 million yuan. It is a high-tech enterprise specializing in the production of tartaric acid. Baojing Biology has been awarded the titles of "National Torch High-tech Enterprise", "Provincial R&D Center", "Hangzhou Innovative Pilot Enterprise", "Yuhang District Industry Leading Benchmarking Enterprise". It was listed as "Hangzhou Listing Guidance Enterprise" in 2013, as "Zhejiang Manufacturing Brand Fostering Enterprise", "Hangzhou Strategic Emerging Industries Fostering Enterprise" in 2016, and Hangzhou. Municipal "Machine Replacement" demonstration application enterprises, many times won the "Yuhang Top Ten Foreign Trade Export Enterprises". He has been commended by the municipal and district governments for many times.

    Baojing Biology is the inventor of L (+) - tartaric acid biosynthesis technology. It has many invention patents. The commercial application of this technology has broken the competitive pattern of the world tartaric acid Market and left a strong mark for China. Mr. Zhang Jianguo, the founder of Baojing Company, is called "Mr. Tartaric Acid of China" by the industry.

    In 2016, Baojing Biology invested a huge amount of money to build 25,000 tons of food-grade tartaric acid plant in accordance with GMP standard. The production process adopts highly automated closed pipeline, with ultra-low emission. It is the most advanced production line of tartaric acid in the world. Advanced production technology and equipment, so that the company's production capacity and quality have been greatly improved, and further enhance the company's core competitiveness.

    The rapid development of Baojing Biology is inseparable from scientific research and innovation. The company pays attention to the introduction and training of scientific and technological input and professional talents, and strengthens the combination of production, learning and research. Jointly established with Zhejiang University and recognized by the state as a provincial R&D center, the center gathers a group of outstanding scientific and technological personnel, such as professors, postdoctoral and postgraduate students, who are the backbone of the company's technological innovation and industrial upgrading. The scientific research team focuses on microbial synthesis, enzyme engineering, process optimization, chemical synthesis and separation, energy saving and emission reduction, process enlargement and other fields to carry out research and development work, which has brought significant economic and social benefits for the company.

    The application of tartaric acid covers building materials, food and pharmaceutical industries, and most of L(+) - tartaric acid produced by Baojing Biology is exported to Europe, America, Australia, Southeast Asia, the Middle East and other regions, and is favored and praised by many well-known foreign companies. Baojing BIOKING has become a well-known professional manufacturer of tartaric acid in the world, and "Baojing BIOKING" is also the preferred brand for customers.

    In 2004, Baojing Biology actively responded to the EU's anti-dumping of tartaric acid against China. After unremitting efforts, Baojing Biology eventually won the "zero tax rate" and became the only tartaric acid export enterprise in China to the EU with the "zero tax rate". In 2012 and 2016, Baojing Biology won the anti-dumping case again. It is an example for Chinese manufacturing enterprises to win a fair position in world trade, and has been commended by provincial, municipal and district commercial departments.
