Shandong Jiejing Group Corporation

What Shandong Jiejing Group Corporation does

Shandong Jiejing Group Corporation is a Chinese seaweed-processing industrial group founded in 1968 in Rizhao, Shandong, that operates as the world's largest manufacturer of alginate and Asia's largest producer of seaweed-derived active substances. The company extracts and processes brown seaweed (primarily Laminaria japonica) into a portfolio spanning sodium alginate and its derivatives (propylene glycol alginate, potassium alginate, calcium alginate), marine bioactive compounds (fucoidan, fucoxanthin, alginate oligosaccharides, brown algae polyphenols), mannitol, and complementary hydrocolloids (xanthan gum, carrageenan, agar agar, guar gum, konjac gum, pectin). Its core technical differentiation rests on a proprietary low-temperature physical wall-breaking and countercurrent extraction process that preserves biological activity without chemical additives, combined with 1000-mesh ultrafiltration and 20+ process stages yielding high-purity outputs. The company is the only Chinese firm industrially extracting fucoidan, fucoxanthin, and brown algae polyphenols at scale.

The company sells primarily B2B into five end-markets: food (food-grade alginate as thickener/stabilizer, PGA as beer foam stabilizer), pharmaceutical and nutraceutical (GMP-certified mannitol, fucoidan), agriculture (seaweed-extract biofertilizers, biostimulants, alginate oligosaccharides as plant elicitors), textile (printing-grade sodium alginate), and dental/cosmetic (alginate impression material, peel-off face-mask alginate). Distribution is conducted via direct international B2B sales (FOB, CIF, CNF terms; L/C, T/T payment), supplemented by attendance at major industry exhibitions including Food Ingredients China, FIE Europe, and Global Ingredients Show Russia. Pricing is quote-based on volume and specification rather than publicly disclosed. A wholly-owned subsidiary, Shandong Hengtai Marine Biotechnology Co., Ltd. (established 2017), markets seaweed bio-organic fertilizers and biostimulants under the Yusen sub-brand.

Commercial leadership rests with President Lin Chengbin (Lin Hefeng), a graduate of Ocean University of China. The company holds a 2014 National Torch Program listing for fiber-grade sodium alginate industrialization and is a vice-chairman unit of the China Biostimulant Development Alliance since 2016. In 2024 the company launched FucoSecret, its first consumer-facing fucoidan dietary supplement, signaling a downstream move beyond pure ingredient supply. The firm is privately held with no disclosed institutional investors, parent company, or external funding rounds.
