Zhejiang Tianyi Food Additives

Zhejiang Tianyi Food Additives is a China-based manufacturer of food additives and related fine chemical products, best known for its gluconate product line. Its core commercial products include sodium gluconate, glucono-delta-lactone, calcium gluconate, potassium gluconate, zinc gluconate, magnesium gluconate, ferrous gluconate, copper gluconate, manganese gluconate, and gluconic acid solutions. The company describes itself primarily as a food-additives producer, while also marketing pharmaceutical-grade gluconates that meet pharmacopeial standards and, in some listings, cyclosporine A API. It operates manufacturing and R&D capabilities in Zhejiang, China and sells internationally across multiple regions. Despite some overlap with nutraceutical and pharmaceutical ingredient supply, the business appears to be primarily an industrial food-ingredients and chemical manufacturer rather than a therapeutics-focused biotech or pharma company.
