Fuxing Glucono-Delta-Lactone (GDL) is a food-grade cyclic ester of gluconic acid produced by Shandong Fuxing Biotech, a leading Chinese GDL manufacturer.We supply bulk Fuxing Gluocono-Delta-Lactone sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Fuxing Gluocono-Delta-Lactone is widely used in bean-curd coagulation, baking powder leavening acid, meat curing: ham, cheese acidification and seafood preservation.
Fuxing Glucono-Delta-Lactone is a white crystalline powder that hydrolyses gradually in water to form gluconic acid.
This gives controlled pH reduction. It is the premier tofu coagulant for silken tofu production due to its gentle, uniform gelling action, and is also used as a leavening acid in baking powder, curing accelerator in meat, and acidulant in dairy desserts.
