Seven Star Lemon: Building a New Benchmark for High-End Bio-Manufacturing in Global Fermentation Industry

As a leading high-tech bio-manufacturing enterprise rooted in Yishui, Shandong Province, Seven Star Lemon Technology Co., Ltd. has emerged as a key player reshaping the global citric acid fermentation industry. Founded in 2018, the company focuses on the deep processing of biological raw materials and the R&D of fine chemical additives, operating a modern production base covering 883 mu. It holds a mature annual production capacity of 450,000 tons of citric acid series products, ranking among the top-tier manufacturers in the global fermentation sector.

Different from traditional extensive fermentation enterprises, Seven Star Lemon adopts a circular industrial model centered on corn deep processing, realizing full industrial chain coverage from raw material refining, biological fermentation to finished product manufacturing and by-product recycling. Beyond mainstream citric acid products, the company diversifies its product layout with high-value downstream products including sodium citrate series and high-protein feed materials, effectively serving food processing, pharmaceutical manufacturing, daily chemical industry and new material auxiliary fields. Its global sales network spans over 130 countries and regions, maintaining long-term stable strategic cooperation with more than 500 internationally renowned brands.

Technological research and institutional innovation constitute the core competitiveness of the enterprise. Certified as a provincial-level “One Enterprise, One Technology” R&D Center, the company insists on industry-university-research collaborative innovation and owns a complete independent intellectual property system. It holds 8 national invention patents and 24 utility model patents, and has participated in optimizing industry production standards, continuously breaking through technical pain points in traditional fermentation efficiency and energy consumption. Meanwhile, the company has obtained ISO45001 occupational health and safety certification, ISO5001 energy management system certification and IP non-GMO certification, forming a comprehensive standardized management system.

In recent years, Seven Star Lemon has gained wide industry recognition for its intelligent and green manufacturing layout. It has been successfully selected into the municipal green manufacturing enterprise list and awarded the provincial advanced intelligent factory title, marking its full realization of intelligent control, low-carbon operation and clean production. By optimizing energy structure and promoting by-product recycling, the enterprise effectively reduces unit energy consumption and carbon emissions, setting a typical example for green upgrading of the domestic bio-fermentation industry. Committed to high-quality global development, Seven Star Lemon continues to empower the upgrading of the global fine additive industry with Chinese intelligent manufacturing strength.
