food addtive glucono delta lactone
Traditional tofu is made by coagulating soy milk with gypsum and brine. Now, a better alternative to gypsum and brine called glucono delta-lactone (GDL), has been invented. Tofu coagulated with GDL is more tender, has a higher flavor and nutritional value, and is absolutely harmless to the body. The boxed tofu available in supermarkets is made using GDL coagulation. Overview Glucono delta-lactone, abbreviated as GDL, with the molecular formula C6H10O6.It is a white crystalline or powdery substance, almost odorless, with a sweet and sour taste. It is easily soluble in water. Glucono delta-lactone is used as a coagulant, mainly in the production of tofu、cheese, and can also be used as a protein coagulant in dairy products. Principle The principle of using glucono delta-lactone to coagulate tofu is that when GDL dissolves in water, it converts into gluconic acid, which has an acid-coagulating effect on the protein in soy milk. Due to the slow decomposition of GDL, the coagulation reaction...
