Our History
Foundation & Initial Development
Seven Star Lemon Technology Co., Ltd. was officially established in Yishui County, Shandong Province, launching the layout of R&D, production and sales for citric acid series products.
Project Construction & Municipal-level Recognition
The project was listed as a key municipal project of Linyi and awarded "Top Ten Excellent Municipal Projects" at the city’s observation review conference. The first phase with an annual capacity of 100,000 tons was put into production, and products were exported to overseas markets for the first time.
Capacity Expansion & Provincial Key Project
Continuous capacity expansion made the project a major provincial project of Shandong. Multiple international certifications including ISO, FSSC22000, HALAL and KOSHER were obtained, steadily elevating industrial standing.
Strategic Cooperation & Resource Expansion
A framework cooperation agreement was signed with Shuifa Agriculture Group to integrate resource strengths, advance large-scale and standardized development of citric acid industry, with products exported to over 40 countries and regions.
Technological Breakthrough & Global Layout
Self-developed high-concentration fermentation technology fills the domestic gap in high-acidity citric acid production. The annual output reaches 450,000 tons, products are sold to more than 130 countries, and partnerships are built with over 500 renowned enterprises including Coca-Cola and Nestlé.
Innovation-driven Industrial Benchmark
Municipal Technology Innovation Center was approved with 8 invention patents and 24 utility model patents. Adopting Industry 4.0 and circular economy models, we forge ahead toward the vision of becoming the world’s most competitive citric acid manufacturer.
